Tens of millions swelter as heatwave blankets the central and eastern US
The National Weather Service (NWS) has issued several extreme heat warnings and advisories as a dangerous and prolonged wave of high temperatures and humidity blankets much of the central and eastern US, with the worst conditions expected to persist into the middle of this week. Several locations recorded their hottest temperatures of the year over the weekend: Salt Lake City, Utah, hit 104F (40C) on Thursday, its first triple-digit reading of 2025, and on Saturday the city of Mitchell in South Dakota also reached 104F, surpassing its previous daily record of 101F (38.3C). Daily high records were broken in parts of Minnesota, Wyoming and Michigan. Cities under active heat alerts include Chicago, Kansas City, St Louis, Detroit, Cincinnati, Pittsburgh, Philadelphia, Washington DC and New York City. The NWS classified some of its warnings as 'extreme heat' alerts, its highest level, due to the severity of the conditions. Some cities – including Boston, New York City, Philadelphia and Washington – could approach or surpass 100F (37.8C) during the peak of the heatwave. New York's Central Park hasn't reached that level since 18 July 2012, the NWS said, while Philadelphia last hit it in June 1994. Humidity is also a factor, with oppressive moisture levels driving 'heat index' values – which factor in humidity to give a sense of how hot it feels to a human – into the triple digits in part of the midwest, Great Lakes, mid-Atlantic and northeast. In some areas of the central US the heat index could reach as high as 115F (46C). Meanwhile, night-time lows around 70F-80F (21C-27C) in urban areas will offer little relief and increase the risk of heat-related illness, particularly among vulnerable populations. In New York City, officials are encouraging residents to take precautions. 'This is the deadliest weather threat we face in New York City – treat it that way,' the city's emergency management agency warned Saturday on social media. 'Don't wait until you feel sick. Heat builds. It compounds. It kills quietly.' Philadelphia's department of public health declared a heat health emergency starting Sunday at noon. Officials are urging the public to stay hydrated, limit time outdoors and check on elderly neighbors and others at risk as the heatwave persists.

US heat wave: Experts share advice on how to stay cool and safe amid weather alerts
The US is currently experiencing its first big heat wave of 2025 thanks to a powerful 'heat dome'. The powerful 'heat dome' is currently covering vast swathes of the country, bringing with it stifling temperatures and oppressive humidity. National Weather Service has issued warnings of severe temperature impacts, with more than 150 million Americans under the highest-level extreme heat alerts. Governor Kathy Hochul declared a state of emergency across 32 Empire State counties in response to the rising temperatures. Philadelphia health officials have also declared a heat health emergency, urging people to look out for each other. Climate change has been exacerbating heat waves, and the problem isn't going away any time soon. An increasingly hot planet — due largely to burning fossil fuels such as coal, oil and natural gas — means already hot regions are getting worse. Heat doesn't just mean canceled events. It also poses a health risk, especially for children, older people and those with certain health conditions. Here are some tips to stay safe in the heatwave. When does heat become dangerous? The answer depends on more than the temperature. The most detailed measurement is called the wet bulb globe temperature (WBGT), which includes temperature, humidity, cloud cover and wind. The heat index, which measures temperature and humidity, is less descriptive but easier to find on weather apps. Both explain why a shaded soccer field on a 90 degree F day (32 degree C) in arid Phoenix may be less risky than an exposed park on an 80 degree F (27 degree C) day in soupy Little Rock. Just based on heat index, NOAA has a chart that calculates how dangerous prolonged exposure can be. For example, a day where temperatures reach 96 degree F (36 degrees C) and 45% humidity would fall into the 'danger' category for prolonged exposure or strenuous activity. The WBGT threshold isn't exact, but recent research suggests that even some young, healthy people can't endure hours of exposure to high heat and humidity. How to cool down Overnight lows can be a particularly dangerous part of a heat wave, said Ashley Ward, director of the Heat Policy Innovation Hub at Duke University. 'Your body needs a reprieve,' she said. 'You don't get that overnight, we start the next day at a deficit.' Heat can worsen labor productivity and lead to more visits to the emergency room. 'When we have overnight temperatures that don't drop below 75 degrees" F (24 degrees C), she said, 'You start to see some pretty extraordinary outcomes with respect to heat illness and heat stroke, and even mortality.' Ward's answer: Find air conditioning. That might be at home, but she said census data overcounts how many people have access. If you can't afford to cool the whole house, Ward said, create a 'cool corner" and sleep there, so your body is prepared to tackle the next day. Evaporative or 'swamp' coolers can help in dry heat, but they increase humidity and can make it more difficult to cool down. In humid places, just use a fan. If you don't have air conditioning, find public places that do, including movie theaters, malls and libraries. Some communities set up cooling centers. Depending on where you live, the Low-Income Home Energy Assistance Program can help you buy a window air conditioning unit, according to the National Council on Aging. Some local nonprofits and civic organizations can also help you access one if cost is a burden. Know your rights if you work outside Knowing what workplace protections you have is important. But there are no federal heat rules to protect workers in the United States. Some states have them, including Washington, Oregon, California, Nevada, Colorado, Minnesota and Maryland, according to the National Resources Defense Council. Other states don't have any. If your state has work rules, try to learn them — though there are still challenges to ensuring regulations are actually enforced, said Bharat Venkat, director of the University of California, Los Angeles Heat Lab. He notes that sometimes shaded areas are too far for workers to take breaks without losing wages, or that management can make it impossible for workers to advocate for themselves. 'Most workers don't actually have control over their time or control over where they work," he said. Within those constraints, finding ways to stay hydrated and lower your body temperature are paramount. You can do this by drinking lots of fluids, wetting clothing or putting cold water or a cold rag on your hands, feet, armpits and neck. A portable handheld fan or a cooling vest can also help. If you're exercising, avoid the hottest times of day and bring more water than you think you need. Knowing heat illness symptoms Heat illness symptoms can vary by person, Venkat said. Medications or underlying conditions can also make it harder to regulate body temperature or notice you're getting too hot. Early trouble signs include heavy sweating, muscle cramps and headache. That's when you stop what you're doing and cool yourself off — for example, by splashing yourself with cold water or finding an air conditioned space. As heat exhaustion sets in, new symptoms arrive, including faster heart rate and dizziness. Next comes heat stroke, which can include confusion, slurred words and fainting. Ward said that's when to call 911. 'Don't be embarrassed to call 911 or go to urgent care when you think you might have overdone it in the heat,' he said.

States of emergency declared across multiple US cities as thousands face triple digit temperatures
Nearly 170 million Americans living across the central and eastern U.S. this week will be forced to endure dangerous heat as city officials declare emergencies and schools announce early closures. In upstate New York, heat index values were expected to reach more than 100 degrees on Monday and Tuesday. It is the last week of school for districts there, and many districts have switched to half-day schedules. 'These changes in schedule were made to ensure the health and safety of both students and staff and to minimize the potential for heat-related illnesses,' Central School District Superintendent Dr. Marie Wiles said in a statement. Governor Kathy Hochul declared a state of emergency across 32 Empire State counties in response to the rising temperatures. Down the East Coast, Philadelphia health officials declared a heat health emergency, urging people to look out for each other. The cause of the triple-digit temperatures is a massive heat dome. AccuWeather warned it could lead to levels of heat and humidity not seen in June in many years. "Bright sun and humid conditions will cause AccuWeather RealFeel Temperatures to peak above 100 degrees for millions,' warned AccuWeather meteorologist Jacob Hinson.
