Extreme heat is smashing temperature records across the region including Canada. And we’re not done yet—heat warnings remain in place.

The Guardian: More than 146 million Americans under extreme heat alerts as dangerous weather fuels outbreak of new wildfires.

A fierce heatwave has shattered temperature records across the US west and has been tied to at least four deaths in Oregon, with more heat on the way as dangerous weather fueled the outbreak of new wildfires.

Oregon faced triple-digit temperatures and saw several records toppled over the weekend, including in Salem, where on Sunday it hit 103F (39.4C), topping the 99F (37.2C) mark set in 1960. Authorities in Multnomah county – home to Portland, where temperatures broke daily records over the weekend – said they were investigating four suspected deaths tied to the heatwave.

More than 146 million Americans were under extreme heat alerts on Monday, as both sides of the country cooked. Excessive heat warnings, the National Weather Service’s (NWS) highest alert, stretch across the west, covering parts of California, Nevada, Arizona, Oregon, Washington and Idaho. Areas on the east coast, including Florida, Georgia, Alabama and Mississippi, were also under heat advisories.

Dozens of locations in the west and Pacific north-west tied or broke previous heat records in recent days. On Sunday, Las Vegas set an all-time record high of 120F (48.8C), while across the desert in Death Valley national park, temperatures reached 128F (53.3 C), breaking a daily heat record and coming just shy of its all-time high. The dangerous temperatures caused the death of a motorcyclist in the park.

Meanwhile, firefighters are battling a flurry of new blazes that sparked in the brutal temperatures over the weekend, with the sweltering conditions posing challenges for fire crews. There were 73 large active fires burning across the country on Monday, according to the National Interagency Fire Center, collectively covering close to half a million acres, and fire conditions are expected to continue through the week.
