A small brush fire started near Mt. Baldy on Friday but no homes are in its immediate path.
The blaze, which started near Mountain Avenue and Shinn Road, was reported about 7:30 p.m. in a forested area and has grown to 20 acres, according to Ed Pickett, a supervising fire dispatcher with the Los Angeles County Fire.
No homes are immediately threatened, he said.
“Heavy fuel with rapid rate of spread,” San Bernardino County Fire Department posted on its Twitter account. “Threat to National Forest.”
