About 150 firefighters worked early today to dig containment lines around a brush fire that destroyed six structures and blackened an estimated 500 acres in the Angeles National Forest northeast of Castaic, authorities said.
No injuries were immediately reported as a result of the so-called Warm Fire, which broke out about 3:30 p.m. Sunday in the area of Lake Hughes and Warms Springs roads, said Joel Gonzalez of the U.S. Forest Service.
It was completely un-contained and was burning "aggressively'' in a southerly direction, the U.S. Forest Service reported about 11:30 p.m. Sunday.
The Forest Service said three structures had burned, but Cheryl Sims, a supervising dispatcher with the Los Angeles County Fire Department, said six had been destroyed.
The three confirmed buildings destroyed were boarded up cabins, Gonzalez said. At least some of the destroyed buildings appeared to be at the shuttered Warm Springs Rehabilitation Center in the 38200 block of Lake Hughes Road, according to Los Angeles County sheriff's Sgt. Brian Allen.
Firefighters were fighting the blaze from the ground and air. About 150 were assigned to the battle, Gonzalez said. Some personnel and aircraft were diverted from another fire in the region. Air drops were not feasible at night due to power lines in the area.
No evacuations were immediately ordered, said Sims.
Area temperatures topped 105 degrees Fahrenheit on Sunday, according to the National Weather Service.
Lake Hughes Road was closed between Castaic and Elizabeth Lake, according to the USFS.
