Is it safe to go there? The U.S. travel advisory system, explained

If you’re planning an international trip, here’s how to use the State Department’s country-by-country guide to minimize your risk of encountering crime, violence, or civil unrest.

On October 19, the U.S. Department of State issued a rare advisory that Americans overseas “exercise increased caution” due to heightened tensions and chances of terrorism around the world, spurred by the Israel-Hamas war. It’s part of a system of travel warnings that’s been around in some form since 1978, designed to help citizens assess how safe a destination might be at a given time.

The current version of the system, which launched in 2018, gives fluid rankings from Level 1 (exercise normal precautions) to Level 4 (do not travel), indicating how risky countries (and in some cases, regions) are for Americans to visit. Rankings are based on factors such as crime rates, civil unrest, and the threat of terrorism. They are meant to give “clear, timely, and reliable information about every country in the world so they can make informed travel decisions,” says a State Department spokesperson.  

Not surprisingly, on October 14, the State Department moved Israel and the West Bank to Level 3 (reconsider travel) and Gaza to Level 4.  

Here’s how the advisories work and how to use them.

What is a travel advisory?

The U.S. State Department inaugurated the travel advisory system in 1978, initially aiming warnings at airlines and travel companies. The system was scrutinized after the 1988 bombing of a Pan Am flight from London to New York , which exploded over Lockerbie, Scotland , killing all 259 passengers and crew plus 11 people on the ground.  

Investigations found U.S. authorities had been aware of a credible threat to a Pan Am flight but hadn’t informed the public. In response, the media and consular offices began issuing travel warnings. In 2018 the U.S. introduced its current four-tier advisory system. There are near-identical versions in Canada , Australia , and New Zealand .

To determine rankings, the State Department considers a nation’s political volatility, crime trends, medical care standards, and the threat of kidnappings or terrorism. (Politics also ends up playing an unspoken role.) Some countries, such as Russia , receive a Level 4 ranking partly because the U.S. government may have limited ability to assist citizens there. Others rise to Level 4 due to a crisis, such as the military coup that recently rocked Niger .  

When the travel advisory system relaunched in 2018, it also included state-by-state evaluations for Mexico , which draws more than 11 million American travelers a year. “Some Mexican states are quite safe for U.S. tourists, while others are riskier due to narco-trafficking violence,” says Ryan Larsen , executive director of the Institute for Global Engagement at Western Washington University. Yucatán and Campeche states are currently at Level 1, while six other Mexican states are at Level 4, including Sinaloa.

Epidemics and natural disasters also can prompt a travel advisory number to rise. Americans may be prompted to reconsider visiting a country recovering from a tsunami or major wildfires, since their presence could hinder rehabilitation efforts. This occurred after the February 2023 earthquakes in Turkey . Such advisories can remain in place for weeks or months.

The strictest-ever advisories came in April 2021, amid the COVID-19 pandemic , says Larsen, who did a thesis   on U.S. travel warnings. At that time, about 80 percent of the world’s countries were at Level 4.

At press time, about 70 percent of the world’s countries were rated Level 1 or Level 2 by the State Department, indicating they’re relatively safe. There are currently 21 countries at Level 3 and 21 at Level 4.

How to use travel advisories

Before booking an international trip, consult the State Department website to see where your destination ranks. While Level 1 and 2 countries are considered relatively safe, you should still register with the U.S. Smart Traveler Enrollment Program (STEP) . This lets Americans overseas use their smartphone to receive travel advisory updates and alerts about emerging dangers in their destination (protests, extreme weather).

Level 3 countries are considered more dangerous for foreign visitors, who should “reconsider travel,” according to the State Department. If you are headed to a Level 3 country, which currently includes Pakistan and Colombia , do wider research on its safety and on the places you’ll visit there, advises Jun Wen , a professor of tourism at Australia’s Edith Cowan University. For instance, while some remote areas in the Colombian Amazon still suffer from drug-related violence, cities such as Cartagena and Medellín are relatively safe. Going on a fully guided group or individual tour can also help you navigate destinations where political unrest or crime might impact your safety.

Travelers should study not only the advisories provided by their own country, but also by the U.S., United Kingdom, and Australia to broaden their understanding of the risks in Level 3 countries, Wen says. As for Level 4 countries, that “Do Not Travel” advice couldn’t be any clearer.

Other countries also issue warnings to their citizens about visiting the U.S. Canada recently informed its LGBTQ travelers they may be affected by laws in certain U.S. states. Australia, meanwhile, cautions its citizens visiting the U.S. to be wary of higher crime rates and gun violence, and even to learn safety strategies for active shooter scenarios.

People who visit countries with Level 3 or Level 4 travel advisories don’t just risk their safety. They also may have travel insurance complications, says Linchi Kwok , tourism management professor at California State Polytechnic University Pomona.

( How travel insurance can—and can’t—help when your plans change .)

They must pay much higher premiums, and their insurance can be invalidated if the advisory for their destination is elevated. “Medical coverage can be minimal, too, particularly if the travel advisory is put up against a disease or an outbreak,” says Kwok. “I encourage Americans to think twice before they travel to Level 3 and especially Level 4 destinations.”

Warnings and their impact on tourism

Travel advisories can be biased, Larsen argues. His research found that, while the U.S. didn’t often overstate the risk of travel to countries with which it had poor relations, it did often understate the danger of visiting nations that were its close allies. Elevating a travel advisory can stoke diplomatic tensions between two countries. Once a country is raised to Level 3 or 4, many tourists will avoid visiting, and many American universities won’t let students join study abroad programs.

The economic ramifications of a level change impact individual businesses such as hotels, restaurants, and travel agencies. For instance, J 2   adventures , a Jewish-focused tour company, saw most of its fall group trips to Israel canceled after the start of the Israel-Hamas war (and the higher advisory level), says cofounder Guy Millo. “This is not just because of the violence on the ground, but because of practical considerations like accessibility of commercial airline flights,” he says. “Most tourists from North America and places around the globe simply couldn’t get here even if they wanted to.”

Everything you need to know about State Department travel advisories

Caroline Tanner

When traveling abroad, the top concern for many Americans is safety.

Whether it is due to ongoing conflict, special events such as the 2024 Paris Olympics , natural disasters like a volcano currently erupting in Iceland or an uptick in crime , conditions of countries can change rapidly, affecting both travelers and locals.

To help keep American travelers safe, the U.S. Department of State issues and maintains travel advisories for U.S. citizens based on current circumstances.

These advisories can be particularly helpful for first-time and younger travelers, though the agency encourages all people to review them for their desired destination ahead of travel.

What are travel advisories based on?

Although travel warnings originate from the State Department and live on its website , they are a joint effort between the State Department's Office of Overseas Citizens Services and U.S. consulates and embassies worldwide.

"We've got our diplomats and consular officers on the ground in all those places, who have more up-to-date information than anyone in Washington could have," said Angela Kerwin, deputy assistant secretary for Overseas Citizens Services, during a Zoom interview Thursday. "But we use a variety of information in order to look at the criteria that go into our travel advisories around the world."

In addition to crime reports, nongovernmental organization reports and those from international organizations such as the United Nations, the government considers nine risk factors in determining the level at which each country's advisory should be set:

  • C — Crime : Widespread violence or organized crime is present in areas of the country. Local law enforcement may have limited ability to respond to serious crimes.
  • T — Terrorism : Terrorist attacks have occurred and/or specific threats against civilians, groups or other targets may exist.
  • U — Civil Unrest : Political, economic, religious and/or ethnic instability exists and may cause violence, major disruptions and/or safety risks.
  • H — Health : Health risks, including current disease outbreaks or a crisis that disrupts a country's medical infrastructure. The issuance of a Centers for Disease Control and Prevention Travel Health Notice may also be a factor.
  • N — Natural Disaster : A natural disaster, or its aftermath, poses danger.
  • E — Time-limited Event : Short-term events, such as elections, sporting events or other incidents that may pose safety risks.
  • K — Kidnapping or Hostage Taking : Criminal or terrorist individuals or groups have threatened to and/or have seized or detained and threatened to kill, injure or continue to detain individuals in order to compel a third party (including a governmental organization) to do or abstain from doing something as a condition of release.
  • D — Wrongful Detention : The risk of wrongful detention of U.S. nationals exists.
  • O — Other : Potential risks are not covered by previous risk indicators. Read the country's travel advisory for details.

Although the most recently added category, Wrongful Detention, only applies to a handful of countries, it's an important criterion for travelers to note when a country has detained a U.S. citizen without cause.

Level 1 to 4 tiered warning system

travel threat levels

Based on that nine-rubric system, plus reports and input from U.S. consulates and embassies in these countries, the agency assigns each country a Level 1 to 4 tiered warning , with 1 being the lowest level, indicating relative safety, and 4 being the highest, meaning travelers should not visit.

Level 1: Exercise normal precautions

This is the lowest level a country can achieve, making it among the safest for Americans to visit. As with any travel, there is always some risk, so every country will always have at least a Level 1 advisory.

Level 2: Exercise increased caution

Under a Level 2 designation, a country has increased safety or security risks, but they likely won't preclude you from traveling there.

Level 3: Reconsider travel

A Level 3 advisory tells travelers to potentially defer trips to the country in question, as serious potential risks exist.

Level 4: Do not travel

The most serious advisories are Level 4 recommendations, which alert you to avoid travel to designated countries and areas due to a greater threat of potentially life-threatening risks and limited resources to help Americans.

What else to know about travel advisories

In addition to the State Department's general travel advisory, a country's information page will also provide any timely alerts from the corresponding U.S. embassy and/or consulate to consider.

There are also certain countries where the agency can provide "carve-outs" to communicate information related to specific areas or regions within a particular country.

"Perhaps the country itself is a Level 3 country, but there is one particular border area that has ongoing kinetic activity of some sort, and we'd say that would be a Level 4," Kerwin explained.

These carve-outs are most often found in Mexico , as the U.S. shares a border with the country and more Americans travel to Mexico for tourism than elsewhere.

"Mexico is a special case. We also have more U.S. consulates than we do in any other country in the world, and for that reason, we are able to provide state-by-state travel advisory levels in Mexico," Kerwin said. "[With] other countries around the world, [we] just simply don't have the ability to have that level of detail; the specificity is greater for Mexico."

travel threat levels

Because data is the main source of information for crafting these advisories, not all alerts can be created equally.

"It is impossible to say that we can apply all nine criteria exactly the same in country A as we do in country B. You're going to have more statistical data of a reliable type for ... Germany than you would Chad," Kerwin explained. "So to compare the exact same report for Germany with the exact same report for Chad is not something that makes sense because it's generally not going to be available."

In those cases, the government relies on its embassies and consulates, which are present in most of these countries, to help inform its alerts.

"We've got people on the ground who are often best positioned to help us evaluate the number of kidnappings, the level of civil unrest, how many terrorist attacks reported or not reported," she said.

Note that a lack of readily available or accurate data doesn't make the country inherently riskier or more dangerous for travelers.

"It just means that we don't have the exact type of data that we would have in another country," Kerwin said. "We would have to rely more heavily on embassy reporting and our folks there, but it does not necessarily mean it is a more dangerous country."

Does a Level 4 alert mean I should avoid traveling there?

In short, the answer is yes.

At the time of publication, there were 19 countries with Level 4 alerts, per the State Department.

"These are the places we deem as the most dangerous for U.S. citizens to travel to, and we would really like U.S. citizens to look at other destinations," Kerwin said. In part, that's because of the limited consular or embassy services available in these places should an American need help.

"Every U.S. citizen gets to make up their own mind on where they want to travel. That's all we can do as a government," she continued. "If a U.S. citizen finds themselves in a situation where they need to travel to one of these countries for whatever reason, we would ask that they look at our travel advisories in advance, read our country information sheet. We would certainly recommend if we have a functioning embassy, that they save that information on their phone so they can contact the embassy if necessary."

But overall, travelers should avoid traveling to Level 4 countries if possible.

"Each of these Level 4 countries will tell you what our concerns are with these countries and [that] our criteria has been met," Kerwin said. "We believe it is quite dangerous to go there."

How often are State Department travel advisories updated?

travel threat levels

When viewing a travel advisory, you'll note at the top the date it was last updated, as alerts are updated on a rolling basis.

Generally speaking, Level 4 and Level 3 alerts are updated at least once every six months, while Level 1 and Level 2 alerts are examined at least once per year, pending evolving circumstances.

"If something changes or some precipitating event, we would do it earlier as needed," Kerwin said.

For example, on Thursday, the U.S. Embassy in Reykjavik issued its own alert regarding a volcanic eruption in southwest Iceland that morning. When embassy alerts are issued for isolated events in a particular region of a country, it does not necessarily reflect the overall level of the country as a whole.

Despite the volcano warning, Iceland remained at Level 1 , as it has since July. If it had been a more widespread eruption affecting general European air travel, that would have prompted the agency to update the travel advisory as a whole.

"Right now, by sending out that security alert, we're saying stay away from the volcano, but if you wanna go have dinner in Reykjavik, follow our regular information we have on our travel advisory," Kerwin said.

That volcano alert also went out via the agency's Smart Traveler Enrollment Program , which sends relevant security updates from the nearest U.S. Consulate, and which Kerwin advised travelers to enroll in as another way to stay safe abroad.

"So anybody who is registered in STEP traveling to or who is living in Iceland would've gotten an email to say, 'Hey, be aware the volcano erupted again today, we're watching it closely; pay attention,'" she explained. "We have those various security alerts that we can send out at any time in a country based on late-breaking events."

Special events, such as the upcoming 2024 Paris Olympics, will also trigger additional and/or more frequent alerts.

"We will be paying special attention to that. We expect there will be a large number of U.S. citizens that are headed in that direction to cheer on our team, and we want to make sure that we are giving them the best information we can about their time when they're traveling," Kerwin said.

Other things to consider when traveling abroad

As with travel in general, the State Department advises Americans heading overseas to prepare in advance.

"We have a slogan we've been using, and I like it; it's called 'travel smart from the start,' and that starts even before you decide what destination," Kerwin said. That slogan applies to details like checking that you have enough validity on your passport (most countries require six months at the time of entry) and buying travel insurance.

Kerwin also advises procuring the contact information for the nearest U.S. government presence (i.e., the embassy or consulate) via the State Department's list of U.S. embassies and consulates .

"Jot down on paper, take a picture on your phone and save the U.S. Embassy/Consulate phone number or email address so you can get in contact with us if there's a problem," she said. "And always be aware of your surroundings ... a heightened level of awareness ... is important for travelers no matter where they're going."

Bottom line

travel threat levels

With travel comes an inherent risk, and the government aims to help travelers remain safe domestically and abroad.

While the decision to travel is ultimately up to the traveler, these travel advisories should be taken seriously.

"Our goal is to always provide the best advice and information we can for U.S. citizens so they can make their decisions as to where they wish they travel," Kerwin said.

Therefore, heed these travel warnings from the State Department via U.S. embassies, consulates and the department's STEP program.

"The final thing — and this is an important one — is to have fun," Kerwin added. "Travel is fantastic — you get to see new cultures, and you get to experience new languages and beautiful countries and beautiful cities. We want U.S. citizens to travel and have fun on their adventures around the world."

Travel Health Notices

Search By Country Name or Disease

CDC uses Travel Health Notices (THNs) to inform travelers about global health risks during outbreaks, special events or gatherings, and natural disasters, and to provide advice about protective actions travelers can take to prevent infection or adverse health effects.

A THN can be posted for: 1) a disease outbreak (higher number of expected cases) in a country or region, 2) sporadic cases of a disease in an unusual or new geographic location, 3) natural and human-made disasters with severe environmental health risks, or infrastructure damage that would limit healthcare services availability and 4) mass gathering events that can lead to disease outbreaks.

More NTAS Information

The National Terrorism Advisory System, or NTAS, replaced the color-coded Homeland Security Advisory System (HSAS). NTAS Alerts are only issued when verified information is available.  After reviewing the available information, the Secretary of Homeland Security decides, in coordination with other Federal entities, whether an NTAS Alert should be issued.

The NTAS Alerts are based on the nature of the threat. In some cases, alerts are sent directly to law enforcement or affected areas of the private sector; while in other cases, alerts are issued more widely to the American people through both official and media channels.

These alerts include a clear statement that there is an imminent and/or elevated threat to the public.

  • An imminent threat warns of a verified, specific, and impending terrorist threat against the United States.
  • An elevated threat warns of a verified terrorist threat against the United States.

NTAS Alerts contain a specific date for when the alert expires. The Alerts do not contain constant or wide-ranging warnings regarding overarching threats. If threat information changes for an alert, the Secretary of Homeland Security may announce an updated NTAS Alert.

Do Not Travel to These Countries

Crime, civil unrest and terrorism are common risk factors for countries that end up on the State Department's "Do Not Travel" advisory list.

In 2024, tourism across the globe is “well on track” to return to pre-pandemic levels, according to projections by UN Tourism.

Global conflicts and natural disasters , ranging from a series of coups across Africa to catastrophic earthquakes in the Middle East affected international travel patterns throughout 2023. Still, international tourist arrivals reached 87% of pre-pandemic levels in 2023, according to estimates by UN Tourism .

In January 2024 alone, about 4.6 million U.S. citizens left the country for international destinations, 17% higher than the same month in 2019, according to the International Trade Administration . But some destinations warrant more caution than others.

On Oct. 19, 2023, following the outbreak of war between Israel and Gaza and flaring tensions in the region, the U.S. State Department issued a worldwide caution advisory due to “increased tensions in various locations around the world, the potential for terrorist attacks, demonstrations or violent actions against U.S. citizens and interests.” Prior to this update, the most recent worldwide caution advisory was issued in 2022 after a U.S. strike killed Ayman al-Zawahiri, Osama bin Laden’s successor as leader of Al Qaeda, causing “a higher potential for anti-American violence.” The worldwide caution advisory remains in effect.

The U.S. State Department also issues individual travel advisory levels for more than 200 countries globally, continually updating them based on a variety of risk indicators such as health, terrorism and civil unrest. Travel advisory levels range from Level 1, which means exercise normal precautions, to Level 4, which means do not travel there.

About 10% of countries – 19 total – have a Level 4: “Do Not Travel” advisory as of Mar. 4. In Level 4 countries, the U.S. government may have “very limited ability” to step in should travelers’ safety or security be at risk, according to the State Department. Crime, civil unrest, kidnapping and terrorism are common risk factors associated with Level 4 countries.

So far in 2024, the State Department made changes to the existing Level 4 advisories for Myanmar, Iran and Gaza, and moved Niger and Lebanon off of the Level 4 list.

Places With a Level 4 Travel Advisory

These are the primary areas the U.S. government says not to travel to right now, in alphabetical order:

Jump to Place: Afghanistan Belarus Burkina Faso Central African Republic Myanmar (formerly Burma) Gaza Haiti Iran Iraq Libya Mali Mexico North Korea (Democratic People's Republic of Korea) Russia Somalia South Sudan Sudan Syria Ukraine Venezuela Yemen

Afghanistan: The Central Asian country is wrestling with “terrorism, risk of wrongful detention, kidnapping and crime,” according to the State Department. U.S. citizens are specifically at risk for wrongful detention and kidnapping. In 2022, the government reinstituted public floggings and executions, and women’s rights are disappearing under Taliban control. The U.S. Embassy in Kabul halted operations in August 2021. Since the Taliban took control , many forms of international aid have been halted . Meanwhile, in 2023, some of the year’s deadliest earthquakes killed more than 2,400 in Afghanistan while the country continues to face a years-long extreme drought.

Belarus: Belarus, which shares a western border with Russia and a southern border with Ukraine, has been flagged for “Belarusian authorities’ continued facilitation of Russia’s war against Ukraine, the buildup of Russian military forces in Belarus, the arbitrary enforcement of local laws, the potential of civil unrest, the risk of detention, and the Embassy’s limited ability to assist U.S. citizens residing in or traveling to Belarus.” The U.S. Embassy in Minsk halted operations in February 2022.

Burkina Faso: Terrorism, crime and kidnapping are plaguing this West African nation. Terrorist attacks may target hotels, restaurants and schools with little to no warning, and the East and Sahel regions of the country are under a state of emergency. In late November 2023, hundreds died in clashes between state security forces and rebels near the country’s border with Mali. In June, more than 2 million people in Burkina Faso were displaced due to “violence linked to al-Qaida and the Islamic State group.”

Central African Republic: While there have not been specific incidents of U.S. citizens targeted with violence or crime, violent crime and sudden closure of roads and borders is common. The advisory states that “Embassy Bangui’s limited capacity to provide support to U.S. citizens, crime, civil unrest, and kidnapping” is a factor in its assessment. Recent data from UNICEF suggests the country has the worst drinking water accessibility of all countries in 2022.

Myanmar (Formerly Burma): Armed conflict and civil unrest are the primary reasons to not travel to this Southeast Asian country, which experienced a military coup in early 2021. Limited health care resources, wrongful detentions and “areas with land mines and unexploded ordnance” are also listed as risk factors. After Ukraine and Israel, Myanmar had the highest conflict-related death toll in 2023.

Gaza : Hamas, a foreign terrorist organization as designated by the State Department, controls much of the Gaza Strip, which shares borders with both Israel and Egypt. On Oct. 7, 2023, Hamas fighters broke across the border into Israel, killing hundreds of civilians and soldiers in a brazen attack that stunned Israelis. On Oct. 10, Israel hit the Gaza Strip with “the fiercest air strikes in its 75-year conflict” according to Reuters . The conflict has since escalated into war between Israel and Hamas, with regular Israeli airstrikes leading to extensive civilian casualties in Gaza. As of mid-December, nearly 85% of Gaza’s population were displaced from their homes, according to UN estimates . The region continues to face shortages of food , water, electricity and medical supplies , with conditions deemed “far beyond a humanitarian crisis.” The State Department warns of terrorism and armed conflict within Gaza’s borders.

Haiti: In July 2023, the Department of State ordered all non-emergency U.S. government personnel and family members to leave the U.S. Embassy in Port-au-Prince in response to the increased risk of kidnapping and violent crime in the country , as well as armed conflict between gangs and police. The travel advisory states that cases of kidnapping “often involve ransom negotiations and U.S. citizen victims have been physically harmed during kidnappings.” The travel advisory also states that “U.S. citizens in Haiti should depart Haiti as soon as possible” given “the current security situation and infrastructure challenges.” A series of gang attacks in late September 2023 caused thousands to flee their homes, and many aid groups have been forced to cut or suspend operations amid escalating violence in recent months.

Iran: Terrorism, kidnapping and civil unrest are risk factors for all travelers to Iran, while U.S. citizens are specifically at risk for “arbitrary arrest.” U.S.-Iranian nationals such as students, journalists and business travelers have been arrested on charges of espionage and threatening national security. Executions in Iran rose sharply between 2021 and 2022, bringing the country’s total to nearly 580 people over the year, according to a report by Amnesty International released in May 2023.

Iraq: The State Department cites “terrorism, kidnapping, armed conflict [and] civil unrest” as cause for the country’s Level 4 distinction. Iraq’s northern borders, and its border with Syria, are especially dangerous. Since the escalation of conflict in neighboring Israel in October, there has been an increase in attacks against Iraqi military bases, which host U.S. troops and other international forces. In October 2023, non-emergency U.S. government personnel and eligible family members were ordered to leave the U.S. embassy in Baghdad.

Libya: Following the end of its dictatorship over a decade ago, Libya has been wrought with internal conflict between armed groups in the East and West. Armed conflict, civil unrest, crime, kidnapping and terrorism are all risk factors. U.S. citizens have been targets of kidnapping for ransom, with terrorists targeting hotels and airports frequented by Westerners. The U.S. Embassy in Tripoli halted operations in 2014. In mid-September 2023, floods, which some say were intensified by climate change , killed thousands in eastern Libya. Clashes between armed factions escalated across the country in the latter half of 2023, including in the capital city of Tripoli and in Benghazi.

Mali: After experiencing military coups in 2020 and 2021, crime, terrorism and kidnapping are all prevalent threats in this West African landlocked nation. In July 2022, non-emergency U.S. government employees and their families were ordered to leave the country due to higher risk of terrorist activity. A U.N. report in August 2023 said that military groups in the country, including both Mali security forces and possibly Russian Wagner mercenaries, were spreading terror through the use of violence against women and human rights abuses. Democratic elections were supposed to occur in February 2024, but Mali’s military junta postponed the plans indefinitely. In December, the U.N. officially ended a decade-long peacekeeping presence in the country, which had been among the agency’s deadliest missions, with hundreds of the mission personnel killed since 2013.

Mexico: Each state in Mexico is assessed separately for travel advisory levels. Six of the 32 states in Mexico are designated as Level 4: Colima, Guerrero, Michoacan, Sinaloa, Tamaulipas and Zacatecas. Crime and kidnapping are listed as the primary risk factors throughout the country. Nearly 112,000 people were missing across the country as of October, a number the U.N. has called “alarming.”

North Korea (Democratic People’s Republic of Korea): U.S. passports are not valid for travel “to, in, or through” this country, home to one of the world's longest-running dynastic dictatorships. The travel advisory states that the Level 4 distinction is due to “the continuing serious risk of arrest and long-term detention of U.S. nationals.” In July 2023, a U.S. soldier fled across the border into North Korea, where he is believed to be in North Korean custody, the first American detained in the North in nearly five years. He was returned to U.S. custody in September 2023.

Russia: The travel advisory for Russia cites its invasion of Ukraine , harassment of U.S. citizens by Russian government officials and arbitrary law enforcement as a few of the reasons for the Level 4 designation. Chechnya and Mount Elbrus are specifically listed as Level 4 regions. Terrorism, civil unrest, health, kidnapping and wrongful detention are all noted as risks.

Russia Invades Ukraine: A Timeline

Somalia: A severe drought resulting from five failed rainy seasons in a row killed 43,000 people in 2022, and caused a famine amid conflict with Islamist insurgents . Violent crime is common throughout Somalia , pirates frequent its coast off the Horn of Africa, and medical facilities, where they exist, have limited capacity. Crime, terrorism, civil unrest, health and kidnapping are all risk factors. In January 2024, some passengers aboard a U.N.-contracted helicopter were taken hostage by al-Shabaab militants after the vehicle crashed in central Somalia.

South Sudan: Crime, kidnapping and armed conflict are the primary risk factors for South Sudan, which separated from Sudan in 2011, making it the world’s newest country . Weapons are readily available, and travelers have been victims of sexual assault and armed robbery.

Sudan: The U.S. evacuated its embassy in Khartoum in April 2023, and the country closed its airspace due to the ongoing conflict in the country, only permitting humanitarian aid and evacuation efforts. Fighting has escalated in the region between two warring generals seeking to gain control after a military coup in 2021 ousted the country’s prime minister. Civil unrest is the primary risk factor for Africa’s third largest country by area. Crime, terrorism, kidnapping and armed conflict are also noted. The International Criminal Court began investigating alleged war crimes and violence against African ethnic groups in the country in 2023. Millions have fled their homes due to conflict, and the U.N. has said its efforts to provide aid have been hindered by a lack of support, safety and resources. As recently as December 2023, the United Nations warned of catastrophic famine , with millions of children at-risk for malnutrition .

Syria: The advisory states that “No part of Syria is safe from violence,” with terrorism, civil unrest, kidnapping, armed conflict and risk of unjust detention all potential risk factors. U.S. citizens are often a target for kidnappings and detention. The U.S. Embassy in Damascus halted operations in 2012. Fighting in neighboring Israel has escalated since October, and the conflict has spilled over into Syria, where the U.S. has carried out air strikes following drone and rocket attacks against American troops in Syria and Iraq, triggered by the Israel-Hamas war.

Ukraine: Russian setbacks in their invasion of Ukraine buoyed hopes in Ukraine in 2023. However, Ukraine is a Level 4 country due to Russia’s invasion, with crime and civil unrest also noted as risk factors. The country’s forces shot down two Russian fighter jets on Christmas Eve 2023, in a move Ukrainian President Volodymyr Zelenskyy said “sets the right mood for the entire year ahead.”

Venezuela: Human rights abuses and lack of health care plague this South American nation, which has been in a political crisis since 2014. In 2019, diplomatic personnel were withdrawn from the U.S. Embassy in Caracas. Threats in the country include crime, civil unrest, kidnapping, wrongful detention and poor health infrastructure.

Yemen: Six of the nine risk factors defined by the State Department – terrorism, civil unrest, health risks, kidnapping, armed conflict and landmines – are all present in Yemen. Despite private companies offering tourist visits to the Yemeni island of Socotra, the U.S. government argues those arranging such visits “are putting tourists in danger.” Civil war and cholera are also both present throughout the country. The U.S. Embassy in Sanaa halted operations in 2015. The country has experienced a relative lull in the civil war fighting, but as peace negotiations have gotten traction, flare ups in the fighting have jeopardized progress. Most recently, the U.S. and U.K. have carried out a series of airstrikes in the country, targeting Iran-backed Houthi sites.

Other Countries to Watch

Since Jan. 1, the State Department has updated travel advisories for 17 different countries as well as for the West Bank and Gaza, adding information about specific regions or risk factors, or simply renewing an existing advisory. Travel advisory levels can change based on several factors in a nation, such as increased civil unrest, policies that affect human rights or higher risks of unlawful detention.

The State Department has given about 25 countries an assessment of Level 3, meaning it recommends people “reconsider travel” to those destinations.

On Oct. 14, one week after the deadly Hamas attack on Israel, Israel and the West Bank were both moved from Level 2 to Level 3, while Gaza remains at Level 4. The region’s travel advisory was updated in November to reflect travel restrictions for certain government employees who have not already left the area, and it was updated again on Jan. 3.

Following the outbreak of the Israel-Hamas war in early October, the U.S. State Department raised Lebanon ’s travel advisory level from a Level 3 to a Level 4 level due to “the unpredictable security situation related to rocket, missile, and artillery exchanges” between Israel and Hezbollah or other militant groups. In December, the U.S. Embassy in Beirut returned to normal staffing and presence, and on Jan. 29, the country was moved back to Level 3. Crime, terrorism, armed conflict, civil unrest, kidnapping and unexploded landmines are listed as the country’s primary risk factors. However, the country’s borders with Syria and with Israel, as well as refugee settlements within Lebanon, are specifically noted as Level 4 regions.

China became a Level 3 country in late 2020, with an update in December 2022 citing “the surge in COVID-19 cases, arbitrary enforcement of local laws, and COVID-19-related restrictions” as the reason for the advisory. In June 2023, the Hong Kong Special Administrative Region (SAR) was moved from the Level 3 to the Level 2 list, but travelers are still advised to be cautious in the area due to “arbitrary enforcement of local laws.” Meanwhile, Macau remains at Level 3.

Following an attempted coup in August 2023, Niger was elevated to Level 4 in August and the Department of State ordered all non-emergency U.S. government personnel and family members to leave the U.S. Embassy in Niamey. In early January 2024, the overall risk level for the country was lowered back to Level 3. Despite the new classification, the State Department still asks non-emergency government personnel and eligible family members to depart the country.

In mid-December 2023 there was an explosion at Guinea’s main fuel depot which has since affected access to health care and basic goods and services. The country was subsequently designated a Level 3 nation after having previously been Level 2. Concerns about civil unrest, health, crime and fuel shortages impacting local infrastructure were listed as the primary risk factors contributing to the change.

Several Level 3 countries are among the worst countries for human trafficking, as designated by the State Department’s annual Trafficking in Persons Report . Level 3 countries on this list include Papua New Guinea, Guinea Bissau, China and Chad. There are also nine Level 4 countries designated as among the worst for human trafficking: Afghanistan, Belarus, Iran, Myanmar, North Korea, Russia, Syria, South Sudan and Venezuela.

Over 70 countries are currently at Level 2, meaning the State Department recommends travelers “exercise increased caution” when traveling to those destinations.

Botswana became the newest Level 2 country on Feb. 26 after having previously been Level 1, with crime noted as the primary risk factor.

France, which saw nationwide protests throughout 2023, has civil unrest and terrorism noted as risk factors for its Level 2 status, and Sweden’s Level 2 status is associated with risks of terrorism.

The Level 2 travel advisory for the Bahamas was updated in January to reflect water safety concerns. The advisory warns that “activities involving commercial recreational watercraft, including water tours, are not consistently regulated” and notes that government personnel are “not permitted to use independently operated jet-ski rentals on New Providence and Paradise Islands.” It also warns visitors to be mindful of sharks, weather and water conditions. The advisory also says that crime is a primary risk factor with gang-on-gang violence contributing to high homicide rates in some areas. Visitors are asked to “be vigilant” and to not physically resist robbery attempts.

Bangladesh 's Level 2 travel advisory was updated in October 2023 to add a note about the country’s general election , which took place Jan. 7, 2024. The advisory states “demonstrations intended to be peaceful can turn confrontational and escalate into violence.” The U.S. has since claimed the country’s election was not free nor fair.

In November 2023, several Level 2 travel advisories were updated with new cautionary information. The advisory for Ghana was updated to reflect threats against LGBTQI+ travelers specifically, noting “anti-LGBTQI+ rhetoric and violence have increased in recent years.” Meanwhile, the advisory for South Africa was updated in February to note that routes recommended by GPS may be unsafe with higher risk for crime.

Turkmenistan was moved off of the Level 2 list to become the newest addition to the Level 1 list on Jan. 22, meaning normal precautions are recommended but there are no risk factors causing travelers to practice increased caution.

The State Department asks travelers to pay attention to travel advisory levels and alerts , review country information pages for their destinations and read related country security reports before going abroad.

U.S. Issues Travel Warning for Mexico Ahead of Spring Break

The warning is asking travelers to “travel smart” and “be informed."

The United States is warning travelers heading to Mexico to be aware of their surroundings ahead of the spring break holiday season.

The warning , which was issued this week by the U.S. Embassy and Consulates in Mexico, reminds travelers to “travel smart” and “be informed” as “thousands of U.S. citizens visit Mexico during spring break” each year. The embassy continued that “while the vast majority travel safely,” visitors should be aware of issues with crime, drugs, unregulated alcohol, drownings, and more. 

“Crime, including violent crime, can occur anywhere in Mexico, including in popular tourist destinations. Travelers should maintain a high level of situational awareness, avoid areas where illicit activities occur, and promptly depart from potentially dangerous situations,” the embassy warned. “U.S. citizens should exercise increased caution in the downtown areas of popular spring break locations including Cancun, Playa Del Carmen, and Tulum, especially after dark.”

The warning also reminded American travelers that drug possession and use is illegal in Mexico, including medical marijuana. It also advised that unregulated alcohol may be contaminated, that counterfeit medication is common, and that guns are illegal in Mexico.

When it comes to the country’s popular beaches, the embassy reminded travelers some beaches may have strong rip tides and “may lack lifeguards, warnings, or signs of unsafe conditions.”

The U.S. Embassy and Consulates in Mexico issued a similar spring break warning last year .

The U.S. Department of State classifies different states in Mexico under different warning levels. While travelers can “exercise normal precautions” when traveling to the Campeche and Yucatan states, the State Department warns them to “exercise increased caution” when heading to places like Baja California Sur (where Los Cabos is), Mexico City, and Quintana Roo (where Cancun is) due to crime.

The State Department also asks American travelers to “reconsider” going to the state of Jalisco, which is home to popular destination Puerto Vallarta , due to the danger of crime and kidnapping.

The State Department recommends Americans who do travel to Mexico keep people at home informed of their travel plans and enroll in the department’s Smart Traveler Enrollment Program (STEP) to both receive alerts and make it easier to locate them if an emergency occurs.

Travelers heading to international destinations can view all current travel advisories on the State Department's website at  travel.state.gov .

U.S. issues travel warning for major European country: ‘Terrorist groups keep planning attacks’

  • Updated: May. 04, 2024, 12:12 p.m. |
  • Published: May. 03, 2024, 12:50 p.m.

The U.S. State Department has issued a new advisory urging travelers to Europe to be extra vigilant when visiting Germany due to concerns about potential terrorist activity.

The advisory, a Level Two – which suggests heightened caution— was released on May 1 and highlights ongoing threats from terrorist groups in Germany, cautioning travelers to remain alert as attacks could occur with minimal warning, noting that “terrorist groups keep planning attacks in Germany.”

The advisory states: “They target tourist locations and transportation hubs. They also target markets/shopping malls and local government facilities. They target hotels, clubs, and restaurants. They also attack places of worship, parks, and major sporting and cultural events. They target schools, airports, and other public areas.”

For reference, Level Three (Reconsider Travel) and Level Four (Do Not Travel) advisories represent more critical levels. However, Germany’s Level Two advisory is noteworthy, given its significant size in central Europe, robust economy, and second-largest population after Russia.

Over the past year, the most severe travel advisories in Europe were primarily linked to the conflict in Ukraine. Do-not-travel advisories were issued for Ukraine (May 2023), Belarus (July 2023), and Russia (September 2023) due to the ongoing hostilities.

If you must travel to Germany, the State Department recommends:

  • Be aware of your surroundings when traveling to tourist locations and crowded public venues.
  • Follow the instructions of local authorities.
  • Monitor local media for breaking events and adjust your plans based on new information.
  • Enroll in the Smart Traveler Enrollment Program ( STEP ) to receive Alerts and make it easier to locate you in an emergency.
  • Follow the Department of State on  Facebook  and  Twitter .
  • Review the Country Security Report for Germany.

Strong geomagnetic storm reaches Earth, continues through weekend

NOAA space weather forecasters have observed at least seven coronal mass ejections (CMEs) from the sun, with impacts expected to arrive on Earth as early as midday Friday, May 10, and persist through Sunday, May 12, 2024. 

NOAA’s Space Weather Prediction Center (SWPC) has issued a Geomagnetic Storm Warning for Friday, May 10. Additional solar eruptions could cause geomagnetic storm conditions to persist through the weekend.

  • The First of Several CMEs reached Earth on Friday, May 10 at 12:37 pm EDT.  The CME was very strong and SWPC quickly issued a series of geomagnetic storm warnings. SWPC observed G4 conditions at 1:39 pm EDT (G3 at 1:08 pm EDT).
  • This storm is ongoing and SWPC will continue to monitor the situation and provide additional warnings as necessary.
This is an unusual and potentially historic event. Clinton Wallace , Director, NOAA’s Space Weather Prediction Center

CMEs are explosions of plasma and magnetic fields from the sun’s corona. They cause geomagnetic storms when they are directed at Earth. Geomagnetic storms can impact infrastructure in near-Earth orbit and on Earth’s surface , potentially disrupting communications, the electric power grid, navigation, radio and satellite operations. SWPC has notified the operators of these systems so they can take protective action.

Geomagnetic storms can also trigger spectacular displays of aurora on Earth . A severe geomagnetic storm includes the potential for aurora to be seen as far south as Alabama and Northern California.

South Korea increases threat level at five embassies due to global North Korean ‘terror’ plot

South Korea ’s foreign ministry has increased the threat level at five of its embassies and consulates overseas as it warned of a North Korean plot to carry out “terrorist” attacks targetting Seoul’ s officials and citizens living abroad.

Seoul’s spy agency, the National Intelligence Service [NIS], said it had recently “detected numerous signs that North Korea is preparing for terrorist attacks against our embassy staff or citizens in various countries, (such as) China, Southeast Asia, and the Middle East”.

The five locations include embassies in Cambodia, Laos and Vietnam, as well as consulates in Vladivostok, Russia, and Shenyang, China, Reuters reported.

The ministry said in a statement: “ North Korea has dispatched agents to these countries to expand surveillance of the South Korean embassies and is also engaging in specific activities such as searching for South Korean citizens as potential terrorist targets.”

The South Korean foreign ministry said the terrorism alert level at the five embassies and consulates had been raised from “Attention” to “Alert”, the second-highest level in the country’s four-tier system, which indicates that there is a heightened likelihood of an attack.

The statement from the foreign ministry said that South Korea’s National Counter Terrorism Center convened a meeting on Thursday to discuss strategies aimed at safeguarding the country’s diplomatic premises and personnel.

Historically, during the Cold War era, North Korea faced allegations of perpetrating multiple assaults on civilian establishments, such as orchestrating bombings at a Seoul airport and targeting a South Korean airliner in the 1980s.

In 2017, the US placed North Korea back on the list of state sponsors of terrorism. It was earlier removed from the list by George W Bush in 2008.

Both Seoul and Pyongyang maintain diplomatic missions, either embassies or consulates, in all five locations where threat levels were increased.

“The end of the pandemic has enabled North Korean agents, previously confined within their country, to travel abroad for missions, while South Koreans are also travelling abroad without any restrictions,” Lee Man-jong, president of the Korean Association for Terrorism Studies, was quoted as saying by AFP.

“Pyongyang appears to be targeting South Korean assets and nationals located in foreign countries with which they have established strong diplomatic ties,” he told the outlet.

Since the Korean War ended in a truce in 1953, North Korea has been accused of conducting a number of attacks against South Korea and its people. These include an attempt to infiltrate the South Korean Presidential Palace in 1968, where armed North Korean guerrillas disguised as South Korean soldiers attempted to assassinate then-president Pak Chong-hui , resulting in casualties on both sides.

Then in 1983, three North Korean armed guerrillas attempted to assassinate then-president Chun Doo-Hwan of South Korea during a state visit to Myanmar [then known as Burma], resulting in the deaths of South Korean officials and injuries to many others.

In September 1996, a North Korean submarine was stranded in the northeast of South Korea , leading to armed agents infiltrating South Korean territory. Some of these agents were discovered dead in a nearby mountain, while others were killed by the South Korean army.

In June 1998, another incident occurred when nine dead bodies and automatic rifles were found in a submarine that had drifted into South Korean waters.

Earlier this year, North Korean leader Kim Jong-un called for his country’s constitution to be changed to declare South Korea its “primary foe and invariable principal enemy”, as relations between the two countries plummeted to their worst level in years.

"Extreme" G5 geomagnetic storm reaches Earth, NOAA says, following "unusual" solar event

By Li Cohen

Updated on: May 11, 2024 / 8:32 PM EDT / CBS News

An "extreme" G5 geomagnetic storm reached Earth on Friday, NOAA's Space Weather Prediction Center said , after issuing a watch earlier in the day warning of the potential for a severe impact. 

The watch followed days of solar activity that sent several explosions of plasma and magnetic fields toward Earth. 

G5 is the strongest level of geomagnetic storm , on a scale from G1 to G5. 

"Widespread voltage control problems and protective system problems can occur," NOAA warns. "Some grid systems may experience complete collapse or blackouts. Transformers may experience damage." 

Radio transmissions and satellite navigation may also be disrupted.

The last G5 geomagnetic storm, in October 2003, caused power outages in Sweden and damaged transformers in South Africa.

A geomagnetic storm also means aurora borealis , otherwise known as the northern lights , could be seen as far south as Alabama and in Northern California.

Earlier, NOAA had issued its first watch for a potential G4-level geomagnetic storm in almost 20 years. "If geomagnetic storms were hurricanes, 'severe' would be category 4," SpaceWeather.com says. 

In a press release on Thursday, NOAA said the most recent series of solar events started on May 8, when a large cluster of sunspots produced "several moderate to strong solar flares." Solar flares are bursts of radiation known to be the solar system's largest explosive events, according to NASA. The area where the flares are occurring is 16 times the diameter of Earth, the NOAA said, and more solar activity is expected. 

That sunspot is so big you may be able to see it with your own eyes  — with your solar eclipse glasses. The spot is known as AR3664 , and it was responsible for most of the geomagnetic activity Friday, the NOAA reported. According to Space.com, it measures about 124,000 miles across and is one of the "largest and most active sunspots seen this solar cycle." 

The NOAA reported that a strong solar flare was observed peaking from AR3664 at 9:23 p.m. Eastern Time Friday. 

"Flares of this magnitude are not frequent," the prediction center said .

There has also been a series of coronal mass ejections (CMEs), which are explosions of plasma  and magnetic fields that come out of the sun's corona, the outermost part of the sun's atmosphere. At least five CMEs appear directed toward Earth and could arrive as early as midday on Friday and persist through Sunday, the agency said. 

"This is an unusual event," NOAA said.

In a call with reporters on Friday, Shawn Dahl, service coordinator at the Space Weather Prediction Center, said that some CMEs "are catching up with other ones." He said officials are expecting a "big shock arrival" when they hit Earth. Dahl said at the time that while officials weren't predicting a G5 storm — the strongest of geomagnetic storms — they couldn't discount a "low-end G5 event."

"We're really buckling down here," Brent Gordon, chief of the space weather services branch, also said on the call.

G4 conditions were detected by Friday afternoon, marking a "major disturbance in Earth's magnetic field," NOAA said, adding that "the public should stay properly informed of storm progression."  

In a forecast discussion at 12:30 p.m. on Friday, NOAA's Space Weather Prediction Center said that solar activity is expected to continue at "high to very high levels" through the weekend, with additional solar flares expected, including X-class flares , the most powerful class of solar flares.

As of Friday afternoon, NOAA said it had observed a moderate solar radiation storm that could expose people in high-flying aircraft to "elevated radiation risk" and cause infrequent issues with satellite operations. 

Radio blackouts have also been detected with an R3 designation, meaning that the blackouts were "strong" on a scale from R1 (minor) to R5 (extreme). At this level, wide blackouts of HF radio communication is expected, as well as loss of radio contact, for about an hour on the sunlit side of Earth, as low-frequency navigation signals decline for roughly an hour. 

"Geomagnetic storms can impact infrastructure in near-Earth orbit and on Earth's surface, potentially disrupting communications, the electric power grid, navigation, radio and satellite operations," NOAA said. "[The Space Weather Prediction Center] has notified the operators of these systems so they can take protective action."

Dahl agreed Friday that the event is "pretty extraordinary" and said that it could impact infrastructure, including high-voltage transmission lines of the power grid. Dahl said that infrastructure operators have been notified to adequately prepare. 

This is the first time a storm watch has been issued for a G4 since January 2005. There is an average of 100 severe geomagnetic storms every solar cycle, but so far, there have only been three observed in the most recent cycle that began in December 2019. The most recent occurred on March 23.

U.S. House Speaker Mike Johnson assailed the hush money case against Donald Trump Tuesday as an illegitimate “sham,” becoming the highest-ranking Republican to show up at court, embrace the former president's claims of political persecution and attack the U.S. system of justice.

It was a remarkable moment in modern American politics: The House speaker amplifying Trump's defense and turning the Republican Party against the federal and state legal systems that are foundational to the U.S. government and a cornerstone of democracy.

Recommended Videos

Johnson, who is second in line for the presidency , called the court system “corrupt.”

Outside the New York courthouse, he decried “this ridiculous prosecution that is not about justice.” He said, "It’s all about politics."

The speaker is leading a growing list of Republican lawmakers who are criticizing the American judicial system as they rally to Trump’s side, appearing at the courthouse to defend the party’s presumptive presidential nominee. Trump is accused of having arranged secret payments to a porn actress to hide negative stories during his successful 2016 campaign for president.

With Trump stuck in court and barred by a judge’s gag order from criticizing witnesses or certain elements of the case, Johnson and the lawmakers are taking it upon themselves to attack the proceedings, now in a fourth week of witness testimony. They're using the trial as a de facto campaign stop as they work to return the former president to the White House.

In portraying the case against Trump as politically motivated, the Republicans are also laying the groundwork to dismiss its significance should the jury convict, and for potential challenges to the fall election, a rematch with President Joe Biden, a Democrat.

Johnson was a chief architect of Trump’s efforts to challenge the 2020 presidential results ahead of the Jan. 6, 2021, mob assault on the U.S. Capitol, and last week he called the hush money trial and the other election-year cases against Trump a “borderline criminal conspiracy.”

“It is election interference,” Johnson said Tuesday, insisting he was appearing on his own to back Trump, whom he called a friend. “And the American people are not going to let this stand.”

Unlike other Republicans showing up to show their support, Johnson did not enter the courtroom where Trump is on trial, but dashed back to Washington to open the House chamber for the day.

Later at the Capitol, Johnson repeated the Republican Party's claims of the justice system being “weaponized” against Trump and said Americans are “losing faith” in it.

Also with Trump on Tuesday were U.S. Rep. Byron Donalds of Florida and North Dakota Gov. Doug Burgum — both considered possible vice presidential candidates — as well as former GOP candidate Vivek Ramaswamy, one of Trump’s current top surrogates.

U.S. Sens. JD Vance of Ohio and Tommy Tuberville of Alabama were among those who attended court on Monday .

Trump’s campaign has lined up allies in recent days to appear at the New York courthouse to attack witnesses and others whom Trump is barred by a judge’s gag order from criticizing himself.

Sen. Rick Scott of Florida said Monday that he appeared last week at the invitation of Trump senior advisor Susie Wiles. The campaign has said others volunteered to come to New York.

“The Democrats are using the court system to go after and prosecute, criminally, a political opponent — that's a crime,” Scott said over the weekend on Fox News. “They’re just thugs trying to stop Trump from being able to run for president.”

In the short term, the Republicans' presence at the courthouse and comments critical of the process have let Trump and his allies amplify their message without risking another explicit violation of the gag order. Trump's attorneys have challenged the gag order as unconstitutional, but an appeals court upheld it on Tuesday.

Johnson specifically attacked the credibility of Michael Cohen, Trump’s former lawyer and fixer who began his second day of testimony in the former president’s hush money trial. And others, too.

He criticized Cohen as “a man who is clearly on a mission for personal revenge," said lead prosecutor Matthew Colangelo “recently received over $10,000 in payments from the Democratic National Committee” and said the daughter of Judge Juan M. Merchan has made “millions of dollars" doing online fundraising for Democrats.

Colangelo, who joined the Manhattan District Attorney's Office in 2022 and previously worked in the U.S. Justice Department in the Biden administration, did paid “political consulting” work for the DNC in 2018, according to federal campaign finance records.

The Republican speaker, who is wholly dependent on support from Trump to keep the gavel, has aimed to strengthen their alliance, particularly as Johnson has come under fire from his own caucus in the House, including a failed effort at his removal by a fellow Trump backer, U.S. Rep. Marjorie Taylor Greene of Georgia.

Johnson made an appearance with the former president at his Mar-a-Lago club last month to announce new House legislation to require proof of citizenship for voting , echoing Trump's baseless claims that Democrats are abetting immigrants entering the U.S. illegally to swing elections — another potential route for Republican challenges to the 2024 election.

There isn’t any indication that noncitizens vote in significant numbers in federal elections or that they will in the future.

And Johnson joined Trump on stage for the Republican National Committee's gala at Mar-a-Lago earlier this month, praising the presumptive presidential nominee and saying House Republicans fully expect to ride Trump's coattails to their own re-elections to keep the majority hold on the chamber.

Johnson has been using the pulpit of the speaker’s office in Washington to attack the U.S. judicial system, criticizing the courts as biased against the former president, claiming the case is politically motivated by Democrats and insisting Trump has done nothing wrong.

The speaker has demurred when asked if the 2020 election was legitimate, and in a departure from the tradition of trust and adherence in U.S. election systems, Johnson and other Republicans have hedged when asked if they will accept the election results of 2024.

Solar storm is powerful enough to disrupt communications: Why NOAA says not to worry

Any solar storm of this magnitude has the potential to interfere with earth's infrastructure. while noaa alerted satellite and grid operators, most people are encouraged to catch some rare auroras..

travel threat levels

An uncommonly strong solar storm is hurtling toward Earth, bringing with it the power to disrupt some communications and even produce some dazzling northern lights .

The storm's impending arrival prompted the National Oceanic and Atmospheric Administration to issue a rare storm watch Thursday to warn about the possible toll it could take when the solar eruption reaches Earth as early as Friday evening.

But before you go preparing for some sort of emergency, most of those at risk of enduring the storm's wrath are power plant operators and those aboard spacecrafts. Instead, if you live anywhere in the northern part of the United States, tonight may be a good time to head outside and try to catch some auroras , NOAA officials said at a Friday news conference.

“It’s a very rare event to happen,” Shawn Dahl, a forecaster and coordinator at NOAA's Space Weather Prediction Center, said Friday. "We haven't seen this in a long time."

Here's what to know about the solar storm.

Solar flares unleash coronal mass ejections toward Earth

NOAA has been tracking the explosive bursts of radiation known as solar flares since Wednesday from a sunspot cluster that's a whopping 16 times wider than Earth.

The solar flares have unleashed at least five coronal mass ejections – clouds of plasma and charged particles – that are now making their way toward our planet at a breakneck pace, said Brent Gordon, chief of the space services branch of the Space Weather Prediction Center.

By releasing solar particles and electromagnetic radiation toward our planet, the coronal mass ejections are what drive the geometric storms toward Earth. Such electromagnetic activity will only increase as the sun continues to reach the height of its 11-year solar cycle,  which NASA said is expected to be in 2025 .

Forecasters use a five-level scale to measure geometric storms. At a G4, this one is just a single level away from being the most severe solar storm possible, according to NOAA. The Severe (G4) Geomagnetic Storm Watch  the agency posted on Thursday marked its first since 2005.

Last December , a powerful burst of energy created the largest solar flare that NASA had detected since 2017.

A destructive  solar storm in 1989  caused electrical blackouts across Quebec for 12 hours, according to NASA, plunging millions of Canadians into the dark and closing schools and businesses. The most intense solar storm on record, the Carrington Event , occurred in 1859 – sparking fires at telegraph stations and preventing messages from being sent.

The last G4 level solar storm  hit Earth in March , one of only three storms of that severity observed since 2019, according to NOAA's Space Weather Prediction Center . The last time Earth was hit by a G5 storm was October 2003, when power outages were reported in Sweden and transformers were damaged in South Africa, NOAA officials said Friday.

Solar storm has potential to disrupt satellites, power grid

Don't expect anything like that this time around.

“We are not anticipating that," Dahl said Friday.

However, any solar storm of this magnitude has the potential – however remote – to interfere with our infrastructure . Anything including communications, the electric power grid, radio and satellite operations are threatened by the looming storm, which could trigger blackouts and disrupt navigation systems.

NOAA officials have seen no evidence from the past that solar storms can disrupt cellular service, Dahl said.

Dahl said NOAA has alerted satellite, grid and pipeline operators so they can prepare.

In the meantime, a NASA spacecraft orbiting about 1 million miles from Earth will help forecasters measure the solar wind and understand the exact timing and threat it poses.

But no matter what happens, rest assured that you and other people are safely protected by Earth’s magnetic field.

How to see the northern lights this weekend

The solar storm is expected to  trigger the aurora borealis , the famous natural light display better known as the northern lights.

From Friday through Sunday, those in the northern half of the U.S. – potentially as far south as Alabama and northern California – have the chance of glimpsing some of the auroras amid the effects of the solar storm, according to NOAA.

If the weather is clear, the best aurora is usually visible within an hour or two of midnight, according to NOAA.

The upcoming solar storm will have particles flowing from the sun that get caught up in Earth's magnetic field,  causing colorful auroras to form  as they interact with molecules of atmospheric gases. Earth's magnetic field redirects the particles toward the poles through a process that produces a stunning display of rays, spirals and flickers that has fascinated humans for millennia.

NOAA also maintains an  aurora dashboard  that provides short-term forecasts of the northern lights.
