Large parts of the Western United States and Central Canada face a prolonged and extreme heat event that is expected to break scores of records over the next week.
🔥 As the heatwave builds, more than 50 million Americans are already under excessive heat watches and warnings and heat advisories from western Arizona to Washington state in the U.S. and from Manitoba to Alberta in Canada.
California’s Central Valley may be particularly hard hit by this heatwave, which the National Weather Service has warned could threaten monthly records over the holiday weekend.
Sacramento could be near 43°C on Labor Day.
San Francisco, Los Angeles, San Diego and Sacramento are all included in excessive heat watches and warnings over the Labor Day weekend, with temperatures forecast to spike to hazardous levels on one of the most popular days for outdoor recreation.
🏴☠️ The most extreme heat will affect the most heat-prone location in the world: Death Valley in California.
The National Weather Service is predicting a high of 51°C degrees on Saturday, 50°C on Sunday and 51°C on Labor Day.
The September record in Death Valley is 50.5°C degrees, so the area has multiple chances of tying or even breaking that. There’s an outside chance it climbs as high as 52°C, which would tie the world record for September.
