The sheep fire went from 35 acres Sunday morning to 775 in the afternoon, according to InciWeb. The fire is only 5% contained.
“Law enforcement went door-to-door with a mandatory evacuation of Desert Front Road and Wild Horse Canyon,” the latest fire update said.
“Wrightwood is under an evacuation warning. There is a road closure from Highway 138 to Lone Pine (Highway 2),” according to the incident’s overview.
CNN has contacted authorities for details on how many residents are under evacuation orders.
The fire started Saturday evening. The case is still under investigation.
Located about 23 miles outside the Los Angeles area, the forest is located “within one of the driest, most fire-prone areas in the United States,” according to the Los Angeles National Forest site.
Southern California firefighters have already warned of a difficult fire season. Robert Garcia, chief of the U.S. Forest Service for the Los Angeles National Forest, told CNN last week that the summer months have a “worrying start.” Firefighting resources have been mobilized since March in Arizona and New Mexico, where the black fire has just become the second largest fire in the state’s history.
“Southern California usually has a fire season in late June and then in the fall,” Chief Garcia said. “But we’re seeing activity all year now.”
The Los Angeles National Forest is already under fire restrictions that are expected to expand around the forest in the coming months, he said.
