Triple-digit temperatures continued to bake Southern California on Sunday as authorities battled a wildfire that has scorched more than 1,400 acres.
The Cabin fire, which began Friday north of Glendora and has destroyed three cabins and an outhouse, was 60% contained as of Sunday evening, up from 20% that morning, the U.S. Forest Service said.
The fire was initially believed to have burned 2,500 acres, but officials said improved mapping of the blaze led them to reduce their estimate of the scorched acreage.
More than 600 firefighters, assisted by seven water-dropping helicopters, are battling the fire. Ten people have been injured so far -- chiefly due to dehydration, heat exhaustion or other maladies tied to the high temperature, Forest Service spokesman Joel Gonzalez said.
Five campgrounds remain under evacuation orders, and a stretch of Highway 39 between Sierra Madre Avenue in Glendora and Highway 2 is closed, officials said.
FOR THE RECORD
Aug. 18, 1:10 p.m.: An earlier version of this article said Highway 39 was closed between Sierra Madre and Highway 2. Highway 39 was closed from Sierra Madre Avenue in Glendora to Highway 2, not from the city of Sierra Madre.
The Rustic fire near Simi Valley, which began the same day, was contained Saturday morning, but the Ventura County Fire Department told residents via Twitter and Facebook that it plans to continue monitoring the area amid the searing temperatures.
Temperatures on Sunday were expected to range from 102 to 108 degrees across the San Fernando Valley, said National Weather Service meteorologist Scott Sukup.
Temperatures are expected to drop off significantly on Monday, falling by 5 to 10 degrees in most areas.
