Firefighters were wrestling with a brush fire Sunday that had consumed at least 1,800 acres with 0% containment near Cogswell Dam in the Angeles National Forest.
They were sent to the location near the dam and West Fork Day Use area at 12:22 p.m., according to a Los Angeles County Fire Department dispatcher.
The blaze was originally reported at about 10 acres, but the U.S. Forest Service updated the response to report that the fire — dubbed “Bobcat Fire” — had burned 1,800 acres “with a rapid rate of spread” and was a second-alarm blaze as of 6:30 p.m.
The fire agency urged motorists to stay away from Highway 39 so it could be used exclusively for emergency vehicles. The highway was later closed at Old San Gabriel Canyon Road.
Structures were being threatened, according to Angeles National Forest officials, who said five engines, three hand crews, four helicopters, five fixed-wing aircraft and two water tenders had been deployed.
A temporary flight restriction was in place over the fire area, and a large plume of smoke could be seen throughout many parts of L.A. County.
Temperatures in the forest were well above 100 degrees.
