The Sharp Fire burns near Wrightwood in the San Gabriel Mountains, Thursday, Aug. 8, 2013.
As the Silver Fire burns 11,000 acres near Banning, a new wildfir has broken out near Wrightwood in San Bernardino County around noon on Thursday, spreading to 60 acres, U.S. Forest Service tweeted Thursday evening.
Several mountain communities are being evacuated ahead of flames, Forest Service officials told the AP. Homes along several winding mountain roads are being evacuated, sheriff's officials told the news outlet. It was unclear how many homes or residents are affected.
The fire is zero percent contained. There are 100 firefighters at the scene along with two helicopters, Ryan Carey, spokesperson for the Angeles National Forest, told KPCC's Wendy Lee.
Firefighters' ground access is limited because of rough terrain, according to the AP.
So far there are no structures lost, Carey said. There have been no road closures, he added.
"The cause is under investigation," Carey said.
Wrightwood is a mountain community popular with skiers located about 40 miles northeast of downtown Los Angeles.
