Tens of thousands of people in southern California have been advised to remain indoors as "emergency" air quality conditions impact parts of the Coachella Valley on Friday.
The Environmental Protection Agency's (EPA) AirNow map, which provides a real-time snapshot of air quality, shows that air pollution levels around Cathedral City and Thousands Palms are "very unhealthy" to "hazardous" on Friday morning.
The warnings mean that the risk of negative health effects from air pollution is increased for everyone, not just vulnerable populations.

Why It Matters
Air pollution and extreme heat pose significant health risks to the general public, in particular for the young, seniors and vulnerable populations such as those with underlying respiratory or cardiovascular conditions.
The EPA warns that the current air pollution levels can lead to serious health issues, including reduced lung function, severe respiratory symptoms including chest pain and aggravated coughs, and increased hospital admissions.
What To Know
The AirNow Map shows that a maroon warning - the highest category - is in force for Cathedral city, which has a population of more than 50,000 people.
A "hazardous" maroon warning means that pollution levels are of "emergency conditions," and that "everyone is more likely to be affected," the AirNow website says.
A "very unhealthy" purple warning - the second highest category - covers Desert Edge, Sky Valley, Thousand Palms and Sunair. AirNow says that the risk of health effects are "increased for everyone" in these areas.
Meanwhile, red warnings are also in force in the Coachella Valley in Rancho Mirage and parts of Palm Desert, along with a large area along the California-Arizona border including Yuma.
Red warnings mean that "some members of the general public may experience health effects; members of sensitive groups may experience more serious health effects."
What People Are Saying
The EPA said that residents should stay inside wherever possible while the air quality is so poor. "Everyone: Avoid all physical activity outdoors. Sensitive groups: remain indoors and keep activity levels low. Follow tips for keep particle levels low indoors."
It added: "The biggest health threat from smoke is from fine particles... [which] aggravate chronic heart and lung diseases - and even are linked to premature deaths in people with these conditions."
Jonathan Grigg, professor of pediatric respiratory and environmental medicine at Queen Mary University of London, told Newsweek previously: "There are very clear links between inhaling particles and earlier death from both respiratory and cardiovascular diseases."
What Happens Next
Air quality warnings are updated regularly by the EPA and National Weather Service.
Residents in affected areas can access daily forecasts and health guidance via airnow.gov and local agencies, with officials providing current information as environmental conditions develop.

Map Shows Countries Where US Has Issued Fresh Travel Warnings
Based on facts, either observed and verified firsthand by the reporter, or reported and verified from knowledgeable sources. Newsweek AI is in beta. Translations may contain inaccuracies—please refer to the original content. The U.S. has issued new travel warnings in response to disease outbreaks in several countries, warning Americans to "practice enhanced precautions" when visiting the affected regions. On August 4, Centers for Disease Control and Prevention (CDC) issued a level 2 travel alert, part of its four-tier system, over global polio in several countries. Travelers are advised to make sure they are up to date with their polio vaccines. Anyone visiting the affected countries who previously completed the full, routine polio vaccine series may also receive a single, lifetime booster dose of polio vaccine. The list of affected countries includes Afghanistan, Algeria, Angola, Benin, Burkina Faso, Cameroon, Central African Republic, Chad, Côte d'Ivoire (Ivory Coast), Democratic Republic of the Congo, Djibouti, Egypt, Ethiopia, Finland, French Guiana (France), Germany, Ghana, Guinea, Indonesia, Israel, the West Bank and Gaza, Kenya, Liberia, Niger, Nigeria, Pakistan, Papua New Guinea, Poland, Republic of South Sudan, Senegal, Sierra Leone, Somalia, Spain, Sudan, Tanzania, including Zanzibar, Uganda, United Kingdom, including England, Scotland, Wales, and Northern Ireland, Yemen and Zimbabwe. In the past month, the CDC also raised Level 2 travel alerts over outbreaks of chikungunya in China, confirmed and suspected cases of diphtheria in Guinea, and outbreaks of mpox in Liberia and Sierra Leone. The CDC ranks travel alerts from Level 1 ("Practice Usual Precautions") to Level 4 ("Avoid All Travel"). Level 2 urges travelers to take stronger precautions due to an elevated risk of infection. Why It Matters These advisories underscore the importance of Americans staying informed about health and safety risks when traveling overseas. Conditions such as mpox and diphtheria can worsen quickly if not managed properly. What To Know Chikungunya in China On August 1, the CDC issued a Level 2 travel alert for Guangdong Province, China, citing an outbreak of chikungunya, a mosquito-borne virus. Most cases have been reported in Foshan city. The disease is spread through mosquito bites and can cause fever, joint pain, headache, muscle pain, joint swelling or a rash. The CDC recommends two approved vaccines for those traveling to affected areas and encourages mosquito bite prevention measures, such as using insect repellent; wearing long-sleeved shirts and pants; and staying in places with air conditioning or that have screens on the windows and doors. Pregnant travelers are advised to reconsider travel to affected areas. Diphtheria in Guinea On July 22, the CDC announced a Level 2 travel alert for the Kankan region in Guinea due to confirmed and suspected cases of diphtheria. The CDC said vaccination against diphtheria was essential to protect against disease, urging travelers to ensure they are up to date on immunizations. Diphtheria symptoms include fever, sore throat, difficulty swallowing, change in voice, shortness of breath, weakness, or fatigue. The CDC advises travelers to avoid contact with people displaying symptoms. Clade II Mpox in Liberia and Sierra Leone The CDC issued another Level 2 alert on July 22 for Liberia and Sierra Leone due to outbreaks of clade II mpox. "Unlike the ongoing global clade II mpox outbreak that began in 2022, which has primarily affected gay, bisexual, and other men who have sex with men (MSM), these outbreaks have affected males and females approximately equally," said the alert. Transmission is occurring through close contact, including through sexual or other intimate contact. The CDC recommends travelers who anticipate intimate or sexual contact in affected areas are vaccinated. The CDC advises travelers to avoid contact with people who are sick with signs and symptoms of mpox, including those with skin or genital lesions. Those who develop new, unexplained skin rashes (lesions on any part of the body), with or without fever and chills, should seek immediate medical care. What Happens Next The CDC will continue tracking global outbreaks and will update its travel health notices as new information becomes available throughout the year.

Map Shows States Where People Told To Monitor for Coughs, Chest Tightness
Based on facts, either observed and verified firsthand by the reporter, or reported and verified from knowledgeable sources. Newsweek AI is in beta. Translations may contain inaccuracies—please refer to the original content. Millions of residents across three states were asked to monitor themselves for health symptoms such as coughing and chest tightness on Monday as poor air quality persisted. Why It Matters Large areas of Maine, Michigan and Vermont faced elevated air pollution levels on Monday, prompting state agencies to issue air quality alerts and health advisories. The warnings, spurred by smoke from ongoing Canadian wildfires, emphasized risks for sensitive groups such as children, the elderly, and those with pre-existing health conditions. The alerts highlighted broader concerns about the impact of wildfire smoke on public health across the U.S. Northeast and Midwest, as similar conditions have become a frequent occurrence this summer due to wildfire patterns. What To Know The Maine Department of Environmental Protection's Bureau of Air Quality issued an alert for particle pollution across the state until 11 p.m. EDT on Monday. The alert covered areas including Oxford, Franklin, Somerset, York, Cumberland, Androscoggin, Kennebec, Waldo and several coastal counties. Officials warned that particle pollution levels were expected to be in the "Unhealthy for Sensitive Groups" range, and recommended people limit strenuous outdoor activity to reduce the risk of adverse health effects. The very young, elderly, people with respiratory conditions such as asthma and heart disease, and those who work hard outdoors, were mentioned as especially vulnerable. Residents experiencing symptoms such as shortness of breath, coughing, throat irritation or chest discomfort were advised to decrease the intensity and duration of outdoor activities.

Motortion/Getty Similarly, the Michigan Department of Environment, Great Lakes and Energy declared an Air Quality Advisory for Monday across the state, spanning Midland, Bay, Huron, Saginaw, Tuscola, Genesee, Oakland, Washtenaw, Wayne and more. Fine particulate matter (PM2.5) levels were projected to reach "Unhealthy for Sensitive Groups" range, with some locations forecasted to hit the "Unhealthy" range. The advisory urged everyone—particularly those with heart or respiratory illnesses—to avoid strenuous outdoor activities and monitor for symptoms like coughing, chest tightness or wheezing. Additional guidance included keeping windows closed, using filtered air systems and limiting activities contributing to outdoor air pollution such as burning wood. In Vermont, the Vermont Agency of Natural Resources issued an Air Quality Health Advisory warning of fine particulates to hit the Unhealthy for Sensitive Groups range on Monday for Eastern Addison, Eastern Rutland, Eastern Windsor, Orange, Western Addison, Western Rutland and Western Windsor counties in effect through midnight. "Sensitive groups should reduce prolonged or heavy exertion," the alert said. "It's okay to be active outside, but take more breaks and do less intense activities. Watch for symptoms such as coughing or shortness of breath." Several other states across the Upper Midwest and Northeast also had air quality alerts in place, although the alerts didn't specify that people should monitor themselves for symptoms such as coughing or chest tightness. What People Are Saying National Weather Service meteorologist John Boris at the Gaylord, Michigan, office told Newsweek: "Right now, our biggest issue is the fact that there really isn't a whole lot of we get a little bit more flow, there's probably a couple more days of us dealing with this, at least in Michigan." An air quality alert issued in Michigan: "It is recommended that, when possible, you avoid strenuous outdoor activities, especially those with heart disease and respiratory diseases like asthma. Monitor for symptoms such as wheezing, coughing, chest tightness, dizziness, or burning in nose, throat, and eyes." What Happens Next The advisories in Maine, Michigan and Vermont were expected to remain in effect through Monday night, with potential for extension depending on smoke migration and weather conditions. Officials continue to urge residents to track air quality forecasts through official resources, heed recommendations for health precautions, and reduce activities—such as open burning—that exacerbate air pollution.
