In Phoenix, 664 Deaths Attributed To Extreme Heat This Year; 102 Days Over 100F For Las Vegas So Far
Brutal heat continues to plague the south-west US, with excessive heat alerts lingering long into September as parts of the region set grim new records for deaths connected to the sweltering temperatures. Autumn has offered little reprieve for cities that have already spent months mired in triple-digit temperatures. This week, Las Vegas, Nevada; Phoenix, Arizona; and Palm Springs, California, are all grappling with severe weather, with highs that have pushed over 100F (38C). More than 16 million people in the US were under heat alerts on Friday, according to the National Weather Service, mostly clustered in the southern tips of Nevada, Arizona and California.
“Late-season heat is dangerous because people are fatigued from fighting heat all summer,” the NWS forecast office in Las Vegas cautioned in an alert, which warned of extreme weather expected to last through the weekend and into next week. “This is especially true this year,” it added, “as 2024 continues to break all-time heat records.” Fueled by the climate crisis, and often exacerbated by concrete cityscapes that cook when temperatures rise, heatwaves are getting longer, larger and more intense.
Las Vegas had its 102nd day of temperatures above 100F on Friday, a new record for the most days in a single year. Several states, including Arizona and California, have experienced their warmest summers on record this year, according to the National Oceanic and Atmospheric Administration, and forecasters are predicting that 2024 may rank as the hottest year – a record just set in 2023. “But it’s not over,” NWS Las Vegas said on Twitter, noting the heat warnings lingering in the forecast through the weekend.
The scorching and sustained heat has taken a devastating toll; heat already ranks as the most lethal weather-related disaster in the US, and deaths are increasing. Heat-associated fatalities are growing across the south-west, where shadeless streets can grow hot enough to cause second-degree burns in seconds. As dangerously hot weather stretches past summer and into spring and fall, the risks for those who don’t have access to cooling have continued to rise.
