Enduring heat wave continues to choke the Southwest as high temperatures will move east

More than 85 million people remained under heat alerts Saturday as the weekslong heat wave continues and intensifies in the Southwest.

Dangerously high temperatures will continue to plague the Western United States throughout the weekend, with temperatures growing hotter in the South early next week.

"Daytime highs will routinely range between 10-20F above normal, equating to daytime temperatures approaching the century mark in the interior Northwest, between 100-110F in central and southern California, and 115-120F+ in the high desert of southern California, southern Nevada, and Arizona," according to the Weather Prediction Center.

More than 100 temperature records are possible through Monday across the West and South.

Death Valley, California, could top 130 degrees on Sunday. That's happened just five times in more than 110 years of record

Phoenix temperatures have reached 110 degrees on consecutive days, and the streak should continue through at least Wednesday.

In Southern California, the Riverside County Fire Department is battling three wildfires that started Friday, including the Rabbit Fire. It grew from 20 acres to 4,500 acres and was 5% contained Saturday, Cal Fire said.
