Yet another heatwave scorched the Western United States Saturday, bringing extreme heat warnings to Southern California and record temperatures in the Southwest and Montana.<\/p>\n
Portions of the Pacific Northwest, already grappling with an onslaught of large wildfires, were under an exceptionally rare \u201cParticularly Dangerous Situation\u201d warning, indicating fires could exhibit rapid growth due to extremely dry conditions and strong winds.<\/p>\n
Preliminary temperature readings from the National Weather Service indicated Phoenix reached 117 degrees Saturday afternoon, breaking the record for hottest temperature for today\u2019s date of 116 degrees, set in 1972. It was five degrees short of the area\u2019s all-time record.<\/p>\n
Las Vegas and El Centro, Calif., were within striking distance of their daily records, and both Great Falls and Helena, Mont., surpassed their daily records in preliminary measurements.<\/p>\n
Officials in Southern California cautioned residents to look out for signs of heat-related illness<\/a>, such as dizziness, confusion, headaches and nausea.<\/p>\n Extreme heat is one of the deadliest climate risks facing California<\/a>. On the hottest days, heat-related illness can account for nearly 1 in every 100 emergency department visits in L.A. County. In 2025, the county recorded 10 heat-related deaths, according to a new dashboard<\/a>.<\/p>\n Multiple days of high heat \u2014 with little relief overnight as temperatures remain high \u2014 can increase the risk.<\/p>\n \u201cWe\u2019ve had these elevated temperatures for the last several days here, and that compounding effect can be significant,\u201d said Rose Schoenfeld, a meteorologist with the National Weather Service. \u201cWe have some elevated humidity across the area that increases those overnight low temperatures a bit as well.\u201d<\/p>\n The National Weather Service recommends limiting outdoor activity to the early hours of the day and staying in air-conditioned spaces during the afternoon and evening. It further advised residents never to leave pets or children unattended in vehicles, and to check in on loved ones.<\/p>\n The region\u2019s heat warnings were set to expire Sunday night, with Schoenfeld noting the heat wave was expected to weaken Sunday into early next week.<\/p>\n The high temperatures are the result of a high-pressure system lingering over the area. As the air\u2019s pressure increases, it heats up. The high pressure also stifles the sea breeze that can bring cooler ocean air onto land. Meanwhile, the region\u2019s sticky humidity is thanks to an airflow pattern bringing moist, tropical air to Southern California.<\/p>\n","protected":false},"excerpt":{"rendered":"Yet another heatwave scorched the Western United States Saturday, bringing extreme heat warnings to Southern California and record…\n","protected":false},"author":3,"featured_media":974620,"comment_status":"","ping_status":"","sticky":false,"template":"","format":"standard","meta":{"footnotes":"","_share_on_mastodon":"0"},"categories":[5123],"tags":[7910,1582,276,176753,42693,94436,367102,2961,224,5337,6231,29975,1589,34961,391103,6280,11449,16776,2549,152301],"class_list":["post-974619","post","type-post","status-publish","format-standard","has-post-thumbnail","category-los-angeles","tag-area","tag-ca","tag-california","tag-daily-record","tag-extreme-heat-warning","tag-heat-related-illness","tag-hot-day","tag-la","tag-los-angeles","tag-losangeles","tag-national-weather-service","tag-pacific-northwest","tag-phoenix","tag-record","tag-record-temp","tag-region","tag-resident","tag-risk","tag-southern-california","tag-sunday-night"],"share_on_mastodon":{"url":"https:\/\/pubeurope.com\/@us\/117023201654014704","error":""},"_links":{"self":[{"href":"https:\/\/www.europesays.com\/us\/wp-json\/wp\/v2\/posts\/974619","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.europesays.com\/us\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.europesays.com\/us\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.europesays.com\/us\/wp-json\/wp\/v2\/users\/3"}],"replies":[{"embeddable":true,"href":"https:\/\/www.europesays.com\/us\/wp-json\/wp\/v2\/comments?post=974619"}],"version-history":[{"count":0,"href":"https:\/\/www.europesays.com\/us\/wp-json\/wp\/v2\/posts\/974619\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.europesays.com\/us\/wp-json\/wp\/v2\/media\/974620"}],"wp:attachment":[{"href":"https:\/\/www.europesays.com\/us\/wp-json\/wp\/v2\/media?parent=974619"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.europesays.com\/us\/wp-json\/wp\/v2\/categories?post=974619"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.europesays.com\/us\/wp-json\/wp\/v2\/tags?post=974619"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
