JUNIPER HILLS, Calif. -- Winds pushed a wildfire burning for nearly two weeks in mountains northeast of Los Angeles onto the desert floor and spread it rapidly in several directions, causing it to explode in size and destroy homes, officials said Saturday.
Meanwhile, officials were investigating the death of a firefighter on the lines of another Southern California wildfire that erupted this month from a smoke-generating pyrotechnic device used by a couple to reveal their baby's gender.
The death occurred Thursday in San Bernardino National Forest as crews battled the El Dorado Fire about 75 miles east of Los Angeles, the U.S. Forest Service said.
In northern Los Angeles County, erratic winds pushed the Bobcat Fire onto the Mojave Desert community of Juniper Hills on Friday after churning all the way across the San Gabriel Mountains. The winds and thick smoke over the area grounded water-dropping aircraft most of the day. Meanwhile, crews on the ground shifted from attacking the blaze to protecting homes because they were outflanked by the flames, fire spokeswoman Kerry Gillibrand said.
The fire grew by nearly 20,000 acres to 142 square miles.
Some residents of Juniper Hills fled as blowing embers sparked spot fires, hitting some homes but sparing others. Bridget Lensing feared her family's house was lost Friday after seeing on Twitter that a neighbor's house three doors down went up in flames.Gallery: Wildfire in Juniper Hills, Calif.
The house stood when she made her way back Saturday afternoon.
"Everything around us is gone," she said.
It wasn't immediately clear how many homes were burned in the area about 50 miles northeast of downtown Los Angeles. A crew will assess the damage once the area is cleared of danger, said fire spokesman Sky Cornell. No injuries were reported.
He said crews were taking advantage of slightly cooler temperatures to make headway Saturday. However, winds were expected to remain strong with possible gusts of up to 25 mph.
Throughout the Northwest, firefighters welcomed cooler weather and rain, as well as much-improved air quality and visibility that would allow some to survey fire activity with drones.
On the south side of the Bobcat Fire, firefighters continued to protect Mount Wilson, which overlooks greater Los Angeles and has a historic observatory founded more than a century ago and numerous broadcast antennas serving Southern California.
The fire that started Sept. 6 had already doubled in size over the past week. It is 15% contained.
Officials said the fire has been challenging because it is burning in areas that have not burned in decades, and because the firestorms across California have limited resources. There were about 1,660 firefighters on the lines.
A statement from the California Department of Forestry and Fire Protection, or Cal Fire, said it was the 26th death involving the wildfires besieging the state.
A new blaze sparked by a vehicle that caught fire was growing in wilderness outside Palm Springs.
To the north, a fire burning for nearly a month in Sequoia National Forest roared to life again Friday and prompted evacuation orders for the central California mountain communities of Silver City and Mineral King.
More than 7,900 wildfires have burned more than 5,468 square miles in California this year, including many since a mid-August barrage of dry lightning ignited parched vegetation.
The El Dorado Fire has burned more than 34 square miles and was 59% contained, with 10 buildings destroyed and six damaged.
