An unusually intense heat dome is bringing dangerous temperatures to parts of the West on Saturday, where about 55 million people are under heat alerts. Most of those people are in portions of California, Nevada and Arizona, although heat alerts stretch north to the Canadian border.
Here’s the latest:
Records at risk: Dozens of record highs are likely to be set this weekend from California to Montana, and it is possible that a few monthly records could be tied or broken as well.
Searing highs: Triple-digit heat stretches from Las Vegas to Montana, with cooler pockets in between. Forecast high temperatures this weekend could reach 118 degrees in Phoenix, 115 in Las Vegas, and in the mid-90s in downtown Los Angeles.
