(CNN) -- A wildfire ripped through a mountain community in Southern California on Tuesday, burning more than 1,000 acres and forcing the evacuation of residents living near the flames, authorities said.
The fire in Lebec, about 75 miles north of Los Angeles, is actively burning.
Residents were being evacuated to a local high school, Anthony Romero, an official with the Kern County Fire Department, told CNN's "Rick's List."
"We don't have a contained percentage yet, but they're doing great," he said of the approximately 150 firefighters battling the flames with the help of helicopters and other aircraft.
The fire has burned some 1,100 acres so far, while some 20 structures have been threatened. No homes have been destroyed, according to Kern County Fire Department officials.
Aerial images of the fire showed thick clouds of smoke blowing down the sides of steep hills as aircraft fly overhead.
A separate brush fire near Mount Diablo State Park, which is east of Oakland, is about 5 percent contained, according to a CAL Fire official.
He said about 250 firefighters are battling the blaze, which has scorched roughly 200 acres so far. Some homes are near where the fire started, but evacuations have not been ordered, he added.
The causes of both fires are under investigation.
