Firefighters battled a pair of fast-moving fires on Tuesday that already consumed about 4,500 acres in the San Gabriel Mountains, prompting the evacuation of about 685 homes as triple-digit temperatures hit the region, reported The Associated Press
Authorities on scene said they were concerned winds would cause the two blazes to merge into one large fire.
The two blazes started midday within an hour of one another and just a few miles apart above the cities of Azusa and Duarte, where it was 109 degrees early Monday evening.
The first blaze erupted shortly after 11:15 a.m. along Highway 39 by the Morris Dam after a vehicle went over the side of the road and caught fire. Flames quickly spread up the canyon, U.S. Forest Service Fire Chief Robert Garcia said.
That fire, burning in the Angeles National Forest in steep terrain above Azusa, had charred 1,500 acres and was 0 percent contained at 9 p.m.
Dubbed the Reservoir Fire, the blaze prompted the evacuation of San Gabriel Canyon, a popular recreation destination. Azusa police issued mandatory evacuation orders for Mountain Cove and Rainbow Ranch. Voluntary evacuations were issued for Crystal Canyon and Mirador.
Soon after the Reservoir Fire broke out, another blaze – the Fish Fire – started less than 4 miles away. It began above homes in neighboring Duarte in the area of Brookridge Road and Opal Canyon roads.
As intense flames and thick black smoke spread, a person with a hose was apparently attempting to defend a home on the flaming hillside. Police vehicles soon showed up and aircraft dropped water and fire retardant in the area.
Horse stables at the Encanto Equestrian Center were in flames, which spread uphill, away from structures, video from Sky5 showed.
“It immediately started burning away from homes toward the forest. That was extremely fortunate for us because we did not have those houses in immediate peril,” Los Angeles County Fire Department Deputy Chief John Tripp said.
The Fish Fire fire grew to 3,000 acres – at 0 percent containment – by about 9 p.m., according to a tweet from the Fire Department.
A sheriff's deputy suffered minor injuries due to smoke inhalation at the Fish Fire, a county fire official said. Tripp later said the injury was for a bee sting.
About 685 homes were evacuated in both fires, according to the City of Duarte. Additional evacuations could be ordered overnight, Tripp said at an early evening news conference.
Structure protection efforts will be in effect through the evening, Tripp said. At least one water-dropping helicopter with night vision will work after dark, he said, and the air attack will continue overnight.
An evacuation center was set up at the Duarte Community Center on Huntington Drive. Small animals may be taken there.
Both electrical transmission and distribution lines were threatened, a spokesman for Southern California Edison said. About 105 customers were without power due the fire in Duarte, Edison spokesman Robert Villegas said.
The brush fires broke out in the fifth year of a statewide drought and on the hottest day of a heat wave in Southern California; the triple-digit temperatures coupled with lower humidity levels had prompted the National Weather Service earlier in the day to warn of extreme fire danger in the region through Tuesday.
It was 112 degrees in the the Morris Dam area just after noon, with humidity at 8 percent, according to the National Weather Service. A southwest wind of 5 to 10 mph, with gusts as high 15 mph in the evening, was forecast.
The two fires were burning in the same general area as last year's Cabin Fire, which erupted Aug. 14 roughly 3 miles north of Highway 39 and Rincon-Red Box Road, according to the wildfire's InciWeb page. The Cabin Fire scorched 1,723 acres.
