Millions Across 11 States Told To Stay out of Sun, Limit Activity
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 Americans across almost a dozen states were instructed to stay out of the sun and limit outdoor activities, as the National Weather Service (NWS) issued a sweeping series of extreme heat warnings and advisories amid dangerous temperatures. Dozens of cities in 11 states throughout the South, Midwest, and Southwest face dangerous heat, prompting health alerts and safety guidance for vulnerable communities. Why It Matters The Centers for Disease Control and Prevention (CDC) warned that extreme heat is the deadliest weather phenomenon in the United States, causing more than 700 deaths annually. Vulnerable populations, including children, seniors, and people with chronic health conditions, face elevated risks of heat-related illness such as heat stroke and exhaustion. Rising temperatures also amplify ground-level ozone pollution, compounding risks for those with asthma or heart complaints.

Getty Images What To Know According to the NWS Extreme Heat Warning map and recent reports, extreme heat warnings are in effect for 11 states—affecting hundreds of cities and millions of residents. The hardest-hit areas were parts of Iowa, southwest Minnesota, northeast Nebraska, and most of South Dakota. These regions are forecast to experience heat index values at or above 110 degrees Fahrenheit. In their statements on the heat warning, the NWS advised: "Drink plenty of fluids, stay in an air-conditioned room, stay out of the sun, and check up on relatives and neighbors." Officials reiterated not to leave children or pets unattended in vehicles, as car interiors can reach deadly temperatures within minutes. "For the Heat Advisory, warm and muggy conditions will continue early this morning. For the Extreme Heat Warning, dangerously hot conditions with heat index values 111 to 115 expected," the NWS said. Simultaneously, less severe heat advisories stretched across the South, Midwest, and Northeast—including Georgia and southeast South Carolina, where forecast heat index values routinely top 100 F. Cities across affected regions have opened cooling centers for residents without air conditioning, with officials encouraging people to stay indoors and avoid outdoor activities during peak heat hours. The exact temperature thresholds that trigger heat advisories vary geographically, but all current warnings indicate conditions that push the human body beyond normal heat tolerance limits. What People Are Saying The NWS in Phoenix, Arizona, said in a statement on Sunday: "Drink plenty of fluids, stay in an air-conditioned room, stay in the shade, and check up on relatives and neighbors. "Do not leave young children and pets in unattended vehicles. Car interiors will reach lethal temperatures in a matter of minutes. "Take extra precautions when outside. Wear lightweight and loose fitting clothing. Try to limit strenuous activities to early morning or evening. Take action when you see symptoms of heat exhaustion and heat stroke." What Happens Next At the time of publication, the latest extreme heat warnings remain in effect until at least 9 p.m. CDT Thursday, with the NWS advising residents to stay informed as conditions may shift.

Dangerous heat continues for over 80 million Americans
Dangerous heat continues across the U.S. as millions face feels-like temperature reaching into the 90s and 100s from the Southeast to the Midwest. St. Louis, Missouri, which has been under extreme heat all week, will continue to be under an extreme heat warning this weekend, with the feels-like temperature reaching up to 114 degrees. Places in South Carolina and North Carolina are also getting in on the extreme heat this weekend, with an extreme heat warning in effect for places like Myrtle Beach, Wilmington and Raleigh for feels-like temperatures reaching between 113 and 115 degrees over the weekend. Heat advisories for feels-like temperatures reaching well into the 90s and up to the 100s are in effect for multiple areas. From Florida to Virginia, including Tampa, Savannah and Richmond; from Texas to West Virginia, including Dallas, Oklahoma City, Memphis, Cincinnati and Charleston; and for parts of the Upper Midwest, including Pierre, Bismarck, and Duluth. The Northeast, while still warm, will be noticeably cooler and drier Saturday into Sunday because of a cold front that swept through, which had brought Friday's storms for parts of the region. Extreme, life-threatening heat wave The major heat and humidity will continue to build up across the Midwest and the Southeast this weekend, setting up a widespread, life-threatening heat wave to take place through much of next week. Extreme heat watches have been issued for Omaha, Sioux Falls, Des Moines, Minneapolis and Duluth -- as well as other parts of Nebraska, Iowa, South Dakota and Minnesota. Feel-like temperatures in these areas will likely reach well into the 90s and into the 100s for spots on Sunday. Meanwhile, consecutive days of feel-like temperatures well into the 100s and exceeding 110 degrees are forecast for millions of Americans from St. Louis to Tampa next week. An "Extreme Heat Risk," level 4 of 4, is in place from Sunday through Thursday for large portions of the Southeast. This highest level is described as "Rare and/or long-duration extreme heat with no overnight relief affecting anyone without cooling/hydration as well as health systems, industries and infrastructure." Fire concern in places dealing with wildfires Fire weather alerts are in place for portions of Utah, Colorado and Wyoming for gusty and dry conditions on Saturday. This dry and windy weather will aid any ongoing fires -- like the Deer Creek Fire that has burned more than 17,000 acres but is 77% contained as of Saturday morning -- as well as help quickly grow any new fires that occur.
