Firefighters were closely watching the wind Wednesday night as they battled a fast-moving, wind-driven wildfire that burned more than 3,000 acres in less than three hours, forcing evacuations and road closures in Los Padres National Forest near Frazier Park.
The blaze in mountainous terrain was being driven by winds that gusted up to 20 mph amid very dry fuel conditions. By late Wednesday, the fire was 10 percent contained and had grown to consume acreage in Santa Barbara, Ventura and Los Angeles counties.
The Hungry Valley State Vehicular Recreation Area and Piru Creek Campground were under a mandatory evacuation order, according to the Kern County Fire Department.
