A fire in the Angeles National Forest north of Glendora has spread to 700 acres since it began about 2:15 p.m. along East Fork Road, according to a spokesman for the U.S. Forest Service.
The blaze was moving north toward the Sheep Mountain Wilderness Area, said John Wagner, an assistant public affairs officer with the forest service.
An evacuation was underway at a mobile home park in the vicinity of the fire, Wagner said. He did not know how many residents had been evacuated. There were no reports of casualties or property damage.
Wagner said seven air tankers from various agencies were battling the blaze. Fifteen engine companies from the Los Angeles County Fire Department were also fighting the fire, a spokesman said.
