The U.S. Forest Service and L.A. County Fire Department are tackling the fire, which started above Azusa and Glendora and has burned at least 250 acres.
Fire crews battled a blaze in rugged terrain in the Angeles National Forest on Tuesday as officials were predicting extreme fire conditions for the next several days in mountain areas of Southern California, reports Los Angeles Times.
Meanwhile, crews are working to contain a wildfire in a rural area of Northern California. The fast-moving wildfire started yesterday about 20 miles southwest of King City in Monterey County.
Officials say it burned a mobile home and more than 3 square miles of grassy, rolling hills. Residents of 20 homes near the tiny community of Lockwood evacuated voluntarily. The fire was 30 percent contained early today, The Associated Press reports.
The fire is visible from U.S. 89 and is expected to grow as temperatures increase and humidity decreases this weekend.
Roads and trails haven't been closed in the area, but officials are urging hunters and visitors in the Manti-La Sal National Forest to use caution with campfires as vegetation is drying, Deseret News informs.
