LOS ANGELES (AP) — A brush fire in a mountainous area north of Los Angeles ignited and spread quickly Thursday, forcing thousands of evacuations.

In LA County, around 4,200 residents and 1,400 structures are under an evacuation order, and another 12,500 residents are under an evacuation warning, said spokesperson Andrew Dowd for the Venture County Fire Department.
The evacuation zones in nearby Ventura County are relatively unpopulated, Dowd said. Fifty-six people were evacuated from the Lake Piru recreation area.
Dowd said the fire was a “very dynamic situation†caused by hot, dry weather, steep and rugged terrain and dry fuel. There were 250 firefighters on the ground coordinating with helicopters and other air support, he said.
LA County Supervisor Kathryn Barger, who represents the district, urged residents to evacuate.
“Extreme heat and low humidity in our north county have created dangerous conditions where flames can spread with alarming speed,” Barger said in a statement. “If first responders tell you to leave, go—without hesitation.â€
