“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.”

In Arizona’s Maricopa county, home to Phoenix, 664 fatalities are believed to have been linked to the heat this year , according to public health officials, who are still working to confirm more than half of them. Southern Nevada, where Las Vegas is located, has seen more deaths this year than in any year prior, with officials confirming this week that there have been 342 fatalities linked to the heat. This surpassed last year’s record, which marked an 80% increase over 2022.
