Millions of People in California Told To Stay Out of the Sun for 2 Days
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 California residents are being warned to avoid sun exposure as an extreme heat wave is expected for much of the state, with temperatures forecast to surpass 100 degrees in multiple regions. The heat is expected to start on Friday and last until Sunday morning. The National Weather Service (NWS) issued extreme heat watches and advisories for the Central Valley, Sacramento Valley, Sierra foothills and other inland areas. It is urging people to stay indoors, remain hydrated and check on vulnerable people. On the other side of the state line, similar alerts affect Nevada's southern valleys, including Las Vegas and Death Valley, where risks remain high through the weekend. Newsweek reached out to the NWS offices in Hanford and Sacramento by phone for comment. Why It Matters The heat event impacts millions across agricultural, urban and foothill communities. High temperatures and limited overnight relief increase the risk of heat-related illnesses—especially for those without air conditioning, as well as children, the elderly and outdoor workers. Authorities have called the situation "dangerous," with health, fire and infrastructure threats expected as the state faces the likelihood of record-breaking temperatures and heightened wildfire danger. An NWS HeatRisk map shows where the worst heat is expected in California and Nevada beginning May 30, 2025. An NWS HeatRisk map shows where the worst heat is expected in California and Nevada beginning May 30, 2025. National Weather Service What To Know The NWS office in Hanford issued an Extreme Heat Watch for the San Joaquin Valley, Kern River Valley, and lower Sierra Nevada foothills, effective from Friday morning through Sunday morning. High temperatures in those areas could reach 105 degrees Fahrenheit, with the greatest risks in Merced, Fresno, Bakersfield and surrounding communities. "Heat related illnesses increase significantly during extreme heat and high humidity events," the NWS said in the alert. Residents are strongly advised to "drink plenty of fluids, stay in an air-conditioned room, stay out of the sun, and check up on relatives and neighbors." Further north, an Extreme Heat Watch was issued for Sacramento and Northern San Joaquin Valleys, parts of the Sierra foothills and the Carquinez Strait and Delta. Expected highs range from 99 to 109 degrees, with overnight lows in the mid-60s to mid-70s. The notice cautioned that "heat related illnesses increase significantly during extreme heat events, particularly for those working or participating in outdoor activities." On the coast, cooler conditions will persist with highs in the 60s and 70s. However, inland cities including Fresno, Bakersfield, Sacramento and Redding are at the greatest risk of extreme heat and related health threats. NWS officials underscored the threat to young children and pets, advising people not to leave them in unattended vehicles because temperatures could become lethal within minutes. The heat event is not confined to California. NWS Las Vegas issued its own Extreme Heat Watch affecting southern Nevada and eastern California, forecasting highs of 104 to 109 degrees in places like Las Vegas, Pahrump and Lake Mead, with above 115 degrees likely in Death Valley. Despite the surge in temperatures, a spokesperson with UC Davis Health Public Affairs told Newsweek: "Temperatures regularly exceed 100 degrees in the summertime, and we are not expecting anything unusual related to this usual heat." What People Are Saying NWS Sacramento, on X, formerly Twitter: "With well above normal temperatures expected this week, Moderate HeatRisk and areas of Major HeatRisk are in the forecast. Widespread triple digits are possible on Friday, with near record to record highs. Practice heat safety!" NWS Hanford, on X: "An Extreme Heat Watch has been issued for much of Central CA valid from 11 AM Fri-7 AM Sun. Max temps will rise well above normal, with highs up to 105° and lead to Major Heat Risk. This level of heat can cause heat-related illnesses for much of the population." What Happens Next The NWS will continue to monitor the evolving heat event and update warnings as necessary. Residents are advised to remain vigilant for health and fire risks during the peak heat advisory period and to follow all safety recommendations from public health and weather agencies.

Lawmakers form Heat Caucus: ‘We've had too many deaths'
An Arizona Democrat and a New York Republican are teaming up to form the Congressional Extreme Heat Caucus in an attempt to find bipartisan solutions for deadly temperatures. 'We hope this caucus can make sure the United States is better prepared for the inevitable increase in temperatures, not just in Arizona and the Southwest but all across the country,' Arizona Rep. Greg Stanton (D) said in an interview. He's creating the caucus with New York Rep. Mike Lawler, a moderate Republican who bucked his party last year by expressing support for the nation's first proposed regulation to protect workers from heat by the Occupational Safety and Health Administration. Advertisement 'Extreme heat kills more Americans each year than any other weather event — over 1,300 lives lost, including 570 in New York alone — and it's a growing threat to the Hudson Valley,' Lawler said in a statement. 'That's why I'm co-chairing the Heat Caucus to drive real solutions, raise awareness, and protect our communities from this deadly risk.'

‘Extreme Heat Watch' underway in Northern California, 104-degree weather forecast
( — An 'Extreme Heat Watch' alert has been issued by the National Weather Service amid triple-digit temperatures forecast in Northern California. After several days of what many people called picture-perfect weather, summer-like heat is expected to touch down in the Sacramento Valley soon. Instead of clear skies mixed with breezy weather, the area may experience temperatures that hit 100 degrees and above. Northern California braces for possible hottest temperature of the year Between Tuesday and Thursday, the weather is forecast to warm up. On Tuesday and Wednesday, temperatures jump to 90 degrees from Monday's 81-degree weather. On Thursday, the heat increases to 95 degrees. However, there will be some relief during those three days. 'We still have a Delta breeze and that will help cool us off, but in a few days, this essentially gets shut off,' said FOX40 meteorologist Dennis Shanahan. Sacramento Weather, Radar & MapsLive Traffic Map By Friday, the region is forecast to have its hottest day of the year so far, 104 degrees. 'This is a little early to be experiencing these kinds of temperatures,' Shanahan said. It's expected to be so hot that NWS issued an Extreme Heat Watch that will go into effect on Friday morning and last through Saturday evening. 'Dangerously hot conditions with temperatures 99 to 109 possible and widespread major heat risk,' NWS said about the upcoming forecast. '(There will be) Limited overnight relief with low temperatures in the mid 60s to mid 70s.' Additionally, NWS said, 'heat-related illnesses increase significantly during extreme events, particularly for those working or participating in outdoor activities.' To prevent illness or heat-related emergencies, NWS recommends to drink plenty of fluids, stay in an air-conditioned room, stay out of the sun, and avoid leaving young children and pets in unattended vehicles. Although the weather is forecast to be extremely hot, officials said local rivers and lakes are still cold, fast, and dangerous for those seeking relief from the heat.

Why ‘excessive heat warnings' won't be part of the forecast
(NEXSTAR) — It may be hard to think about sweltering temperatures in early March, but the National Weather Service (NWS) is already rolling out changes to the weather alerts used to inform the public of the dangers of impending heat. Americans may be familiar with 'Excessive Heat Watches' and 'Excessive Heat Warnings,' issued when potentially dangerous heat conditions are in the forecast. Starting this month, those alerts will be no more — sort of. Like it did with wind chill alerts in fall, the NWS is adjusting the names of its heat watch and warning alert. Instead, dangerous heat conditions will trigger an 'Extreme Heat Watch' or an 'Extreme Heat Warning.' Why you'll no longer see 'Wind Chill Warnings' this winter The guidelines are the same as when they were considered 'Excessive' alerts. An Extreme Heat Watch can be issued when 'conditions are favorable for an extreme heat event but its occurrence and timing is still uncertain.' Guidance from the NWS encourages rescheduling outdoor events and ensuring the most vulnerable — children, the elderly, and pets — have a place to stay cool when watches like this are issued. When 'extremely dangerous heat conditions are expected or occurring,' an Extreme Heat Warning is issued. You may be encouraged to avoid outdoor activities, remain hydrated, and stay in air-conditioned spaces as much as possible. Renaming the heat watch and warning is part of NWS's Hazard Simplification Project, which is intended to 'better convey that heat is dangerous.' A total lunar eclipse and blood moon will be visible in March: How and when to watch Another heat-related alert, the Heat Advisory, will not be renamed. These are issued when dangerous heat conditions are likely but not severe enough to trigger a watch or warning. The specific conditions that prompt any heat alert vary by area. The NWS points to Florida, where residents are better prepared for 90-degree heat than in, say, Alaska. In Wisconsin, for example, daytime heat index values between 100 and 104, or heat indices between 95 and 99 for four consecutive days, can activate a heat advisory from the local NWS office. An extreme heat warning can be activated if the daytime heat index will be 105 or higher or 75 or higher at night for at least 48 hours. The NWS also provides a HeatRisk tool, a five-point scale that ranks the risk of heat-related impacts nationwide. It takes into account how unusual the high temperatures are for the time of year, how long the heat will last through the day and night, and if the temperatures 'pose an elevated risk of heat-related impacts' according to data from the Centers for Disease Control and Prevention.
