A brush fire raging out of control in Los Padres National Forest had grown to at least 3,000 acres and crossed into Los Angeles County on Wednesday evening, officials said.
The Grand fire, which started in Kern County near the Grapevine, forced the evacuations of a state park and a campground, fire officials said.
The blaze crossed into Los Angeles County on Wednesday evening, Lt. Dana Albro of the Kern County Sheriff's Department told The Times.
About 800 firefighters were battling the blaze, but no structures were being threatened, the Kern County Fire Department said.
Crews on the ground were being aided by seven air tankers and four helicopters that were making repeated water and fire-retardant drops as flames burned through brush and light grass, fire officials said.
