Following a record-setting, lethal heat wave that hit the Southwest U.S. on summer’s first day, more than a dozen wildfires have popped up all throughout the region as of late Monday.
Another wildfire popped up in the San Gabriel Canyon near Los Angeles Monday, quickly consuming about 1,500 acres.
Billowing smoke could be seen from nearby Dodger Stadium.
The two had not combined as of 8:30 p.m. PT, the county fire department said on Twitter.
About 700 firefighters are on the scene to battle the pair, KCBS reported.
Also in the Los Angeles area, the city of Burbank — which is home to Warner Brothers and Walt Disney studios — hit 111 degrees Fahrenheit, setting a new record, according to the National Weather Service.
The hottest temperature recorded in the United States on Monday also came in California, but further north. It was 126 degrees in Death Valley, the NWS said.
Elsewhere in California, evacuations were ordered in San Diego County as fires continue to rage near the U.S.-Mexico border. And a large wildfire in Santa Barbara County also forced mandatory evacuations.
The record-setting heat has been deadly in Arizona, where six people were killed over the weekend, authorities said.
Five hikers died — two in Phoenix and three near Tucson — according to authorities.
In Phoenix, a 28-year-old female hiker died Sunday and a 25-year-old male hiker died Saturday, according to Larry Subervi, a Phoenix Fire Department spokesman.
Pima County Sheriff Chris Nanos said at a news conference Monday said three hikers died Sunday near Tucson and another is missing.
“It’s just too dangerous for my team to be out here,” Nanos said.
It was so hot, a woman in her fifties died from heat exposure while going for a walk in the middle of the city, Nanos said.
Nanos urged people to stay indoors for their safety — and for the safety of others.
“If not for your own safety, [then stay inside] for the safety of my team and these volunteers who come out here and do this all the time,” he said. “This week, until these temps come down, get your exercise at home. Get your exercise indoors. Or just stay inside. It’s too hot.”
Much of the current heat wave can be attributed to a so-called heat dome — a pattern that can lead to record-setting temperatures and heat waves — according to CNN Meteorologist Rachel Aissen. A heat dome occurs when air is capped by the upper atmosphere in the same location: The air hits the cap and returns to the surface, continuing to heat it like a convection oven.
