"If you are within a UV Alert region extra precautions should be taken to protect oneself from the sun's UV radiation," the alert advised.
Health officials advise minimizing UV exposure by staying out of the sun from 10 a.m. to 4 p.m., regularly reapplying sunscreen, wearing protective clothing and seeking shade.
Extreme heat warnings were in place from the NWS early this week for multiple states, including Arizona, California and Nevada.
Grand Canyon hikers were warned to limit physical activity because of forecasts of extreme heat, with "dangerously hot conditions" below 4,000 feet expected on Monday.
Daytime temperatures were set to range from 102 degrees Fahrenheit at Havasupai Gardens, to 114 degrees at Phantom Ranch.
"Between the hours of 10 a.m. and 4 p.m., hikers should be out of the canyon or at Havasupai Gardens or Bright Angel campgrounds," the NWS said at the time. "Physical activity is discouraged," it added.
Elsewhere, heat advisories were also in effect for New Mexico and West Texas.
What People Are Saying
AccuWeather meteorologist Alex DaSilva previously told Newsweek: "The best advice for people is to limit time outside in the sun during peak heating hours if possible and to use sunscreen. It is also recommended to wear a hat if spending a lot of time outside. People are also urged to stay hydrated in the heat."
Richard Weller, a professor of medical dermatology at the University of Edinburgh, previously told Newsweek: "Sunburn is a risk factor for melanoma skin cancer, which is the most serious of the skin cancers."
What Happens Next
AccuWeather meteorologist Alex DaSilva earlier told Newsweek that UV levels would likely keep rising as summer approached.

System could bring heavy rain to parts of Central America: See storm tracker
The National Hurricane Center said Friday morning, June 27, it is monitoring a system in the Atlantic basin that could produce heavy rains over portions of Central America. Hurricane center forecasters said an area of "disorganized showers and thunderstorms" currently over the northwestern Caribbean Sea and the adjacent land areas is forecast to move west-northwestward into the Bay of Campeche Saturday or Saturday night, where an area of low pressure could form. "Subsequent development is possible on Sunday or Monday if the system remains offshore of the coast of Mexico," the hurricane center Friday morning. However, regardless of development, locally heavy rains are possible over portions of Belize, Guatemala, and southeastern Mexico during the next few days. The hurricane center gives the system a 20% chance of development through the next seven days. System in Pacific expected to strengthen into tropical depression in coming days Meanwhile in the Pacific, the hurricane center said it is continuing to monitor a system, currently labeled as EP95, it expects to become a tropical depression soon. Hurricane center forecasters said Friday morning that showers and thunderstorms associated with a broad area of low pressure located a few hundred miles south of the Gulf of Tehuantepec "have changed little overnight and remain disorganized." The NHC said environmental conditions are forecast to become more conducive for development during the next couple of days, and a tropical depression is "expected to form by late this weekend or early next week" as the system moves west-northwestward off the coast of southern Mexico. The system has a 50% chance of formation through the next 48 hours and a 90% chance of formation through the next seven days.

Hurricanes are born in the tropics, above warm water. Clusters of thunderstorms can develop over the ocean when water temperatures exceed 80 degrees Fahrenheit. If conditions are right, the clusters swirl into a storm known as a tropical wave or tropical depression. A tropical depression becomes a named tropical storm once its sustained wind speeds reaches 39 miles per hour. When its winds reach 74 mph, the storm officially becomes a hurricane. Prepare now for hurricanes Delaying potentially life-saving preparations could mean waiting until it's too late. "Get your disaster supplies while the shelves are still stocked, and get that insurance checkup early, as flood insurance requires a 30-day waiting period," NOAA recommends.

A rare cold snap stuns Uruguay, hitting the homeless hard and causing 7 deaths
MONTEVIDEO, Uruguay -- An unusual gust of frigid air extending from Antarctica has blasted the small South American nation of Uruguay, leading to the deaths of at least seven homeless people this week and prompting authorities to declare a state of emergency as they scrambled to open shelters. The polar front first dumped the mass of freezing weather on Uruguay on Monday, shocking a coastal nation with flat terrain accustomed to mild winters in the Southern Hemisphere. Light snow dusted parts of the country for the first time in four years as temperatures hit minus 3 Celsius (26 Fahrenheit) and windchill readings dipped far below that. But the freeze was breaking on Thursday, with temperatures expected to rise across the country in the coming days. As health officials issued numerous warnings about the dangers of frostbite and hypothermia, homeless people faced potentially devastating circumstances. Outreach workers fanned out around the city, trying to convince people to come indoors. The seven homeless people who died from exposure to the cold were found in various parts of the country — one man who had been sleeping under a bridge, another in a bus station, another in a tent near the river. The homeless population in the economically stable nation of 3.4 million has steadily climbed in recent years, with the Ministry of Social Development in 2024 reporting over 2,700 homeless people — the vast majority in the capital of Montevideo. President Yamandú Orsi this week invoked rare executive emergency authorities that empowered police and other officials to forcibly remove homeless people from the streets, citing a level of risk for the rough sleepers that Uruguay has seldom seen. "The possibility of mandatory evacuation has been applied for the first time because the scale of the problem really requires other tools,' said Leandro Palomeque, director of Uruguay's National Emergency System. Authorities opened 32 new warming centers and three more sprawling evacuation spots — including by converting public gyms and a police academy — and prepared some 1,000 extra beds. Inside one shelter late Wednesday, social workers distributed blankets and hot meals to scores of people who warmed themselves around the steaming vats of meat stew, their faces flushed from the searing winds. Some said police forcibly removed them from the street. 'I was lying on a small table, and the police came and told me I couldn't be on the street,' said Mauricio Rodríguezs. ' I didn't want to come.' Others, reaching the limit of how much they could withstand, sought out a warm bed. 'The worst time of winter is dusk, when the cold starts to set in and your body can't take it anymore,' said Lucas Bilhere, 19, wrapping himself in a blanket in the Montevideo evacuation center. His puppy, Alaska, pranced around the orderly rows of vinyl mattresses strewn with donated sheets where hundreds of people slept bundled-up on the polished gymnasium floor. Rumpled shirts and damp socks hung from the nets of soccer goals. Unlike in normal shelters, the warming centers allowed homeless people to bring pets and personal belongings and remained open during the daytime. As much as Bilhere said he dreaded this wintry weather, he feared just as much what would happen when the cold snap passed and the emergency shelters closed. 'My dream is to have my own home ... and sleep warm,' he said. ' I wish that for everyone.'

Millions of Americans were urged to stay indoors Friday as hot and humid conditions were expected to blanket large portions of the U.S. The National Weather Service (NWS) issued heat advisories across some 13 states, while an extreme heat warning was in effect for southern Arizona. Why It Matters The Centers for Disease Control and Prevention says extreme heat can trigger heat-related illnesses, particularly among seniors, small children, and people with chronic health issues. Warning signs include muscle cramps, profuse sweating, lightheadedness, and nausea. The agency reports that over 700 people in the U.S. die from extreme heat each year. Hotter conditions can also increase ground-level ozone, compounding health concerns.

Heat index values reflect how hot it feels to the human body when both humidity and air temperature are taken into account. Peak index values up to near 105 were possible for southern Illinois, southwest Indiana, western Kentucky, and southeast Missouri, according to the NWS. Parts of Tennessee and Alabama faced conditions as high as 107 degrees, while central, eastern, north central, and southeast Arkansas could see heat index values up to 109, the agency said. "Drink plenty of fluids, stay in an air-conditioned room, stay out of the sun, and check up on relatives and neighbors," the NWS advised. Meanwhile, Arizona residents in counties including Pima and Pinal are being warned of "dangerously hot conditions" next week. The Tucson office of the NWS said the heat risk increases significantly during such events, urging people to plan activities during cooler parts of the day and remain hydrated. What People Are Saying NWS Phoenix, Arizona said on X, Thursday: "The warmup continues through the rest of the week and into the weekend as temps reach back towards near and above normal levels. A few spots will get close to 110°F as early as tomorrow, with 110°F-115°F forecasted for most of the lower deserts by next Monday." NWS Little Rock, Arkansas said on X, Friday: "Another hot day is expected. Scattered afternoon/early evening showers & storms could cool temps down. Best chances for rainfall today will be over northwest half of the state. Better rain chances for the remainder of the state will come over the weekend into next week." What Happens Next At the time of writing, the latest heat advisories were in effect until Friday evening. Meanwhile, the extreme heat warning for Arizona was in effect for Monday morning through Monday evening.
