West Coast Braces for Potentially Record-Breaking Heat as California Wildfire Continues
Excessive Heat Warnings stretch from Arizona to Washington.
— -- As a wildfire burns through a California camping area, West Coasters from Arizona to Washington are bracing for dangerous, potentially record-breaking heat.
Above normal temperatures are expected to soar to 105 to 120 degrees in the Southwest and 90 to 100 degrees in the Pacific Northwest.
Record high temperatures are possible today in Phoenix -- where the record for the day is 114 degrees -- as well as Las Vegas, where the record for the day is 107 degrees.
Tomorrow temperatures could potentially hit 117 in Phoenix; 114 in Palm Springs; 110 in Las Vegas; 100 in Portland and 97 in Yakima, Washington.
As the expected heat wave looms, a wildfire that ignited Wednesday afternoon in the Chimney Peak campground area in central California, about 80 miles east of Bakersfield, has now burned through more than 1,800 acres.
More than 500 personnel are involved in fighting the fire, which today is 33 percent contained, Michelle Carbonaro, Public Information Officer for the South Central Sierra Interagency Incident Management Team, told ABC News.
The cause was determined to be "human," but no further details were released, Carbonaro said today.
One injury was reported and no structures were lost, Carbonaro said.
