Translations may contain inaccuracies—please refer to the original content. An extreme heat wave prompted the National Weather Service (NWS) to issue advisories affecting millions of people across at least five U.S. states—California, Nevada, Montana, Oregon, Arizona and Idaho—with officials warning residents to stay indoors and avoid sun exposure as temperatures soar above 100 degrees Fahrenheit. Why It Matters Heat advisories and extreme heat warnings issued by the NWS could impact public health and critical infrastructure in affected regions. High temperatures—combined with little overnight relief—raised the risk of heat exhaustion, heatstroke and wildfires. Vulnerable groups, including children, older adults and those working or living without air conditioning, face heightened danger. What To Know The NWS Heat Advisory and Extreme Heat Warning maps confirmed warnings for broad portions of California and parts of Nevada. Although these areas often see temperatures in the triple digits during the summer, this is one of the first heat waves of the season and some people might be unprepared. In California, dangerous heat was forecast for the Sacramento Valley, Central Valley and inland counties, with the NWS Sacramento office projecting temperatures up to 107. Central California cities—including Merced, Bakersfield and Tulare—faced highs of 106, while the southern valleys and mountainous zones were expected to see heat reaching the low 100s. The sun rises in California. The sun rises in California. johnemac72/Getty Southern Nevada—including Las Vegas, Pahrump and Death Valley—was placed under an Extreme Heat Watch, with highs between 104 and 115, according to the NWS Las Vegas office. Extreme heat warnings also stretched into northwest Arizona. The heat wave spread to Oregon, Idaho and Montana, sparking warnings in the northern states. Along with staying out of the sun, people were advised to wear lightweight clothing and stay hydrated. Authorities cautioned that the risk of heat-related illness—dizziness, nausea, heavy sweating—would be elevated, especially during afternoon and early evening hours. In addition, NWS officials warned about leaving pets and children unattended in vehicles and noted the increased risk of wildfires because of low humidity and winds. Hospitals and emergency services in California and Nevada anticipated a possible surge in heat-related medical cases. Michelle Shahbon, emergency room manager at Shasta Regional Medical Center, previously told Newsweek that their team expected an uptick in patients and advised residents to stay hydrated and limit outdoor exposure during peak sunlight hours. What People Are Saying NWS meteorologist Brian Conlan, who works at the Missoula, Montana, office, told Newsweek: "While this is probably abnormal for us, many locations are going to be 15, 20, and in some places 25 degrees above normal, it has happened before. Most of the areas that may see their records broken, those records were set in '86." An NWS forecast issued on Friday: " ... record high temperatures will be threatened across interior northern California today, expanding into the Great Basin, Idaho, and as far north as western Montana on Saturday. The anticipated heat in the Southwest for the next couple of days has led to the issuance of Extreme Heat Warnings for the dangerous heat for portions of southernmost Nevada, southeast California, and northwestern most Arizona." What Happens Next The heat wave is expected to last through the weekend and it's likely that updates will continue to be issued by the NWS. It's possible that the heat wave could break records in some areas and is coming earlier than expected in some states.

Why you'll no longer see ‘excessive heat warnings' in the forecast
(NEXSTAR) — It may be hard to think about sweltering temperatures in early March but the National Weather Service is already rolling out changes to the weather alerts used to alert us to the dangers of impending heat. You 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 National Weather Service 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 National Weather Service 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 National Weather Service 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 National Weather Service 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.
