High temperatures and heavy fuel caused the fire to quickly spread from five acres to 1,000 acres within a span of about an hour. Firefighters are dealing with 10 mph winds, which triggered small spot fires around the blaze initially ignited.
Firefighters battling the blaze were reported to have suffered some minor injuries.
The flames were seen moving dangerously close to power lines. Southern California Gas Co. and Los Angeles Department of Water and Power crews were called to the scene.
