Some evacuation warnings were lifted and repopulation efforts were underway Friday as firefighters attained 55% containment of the 113,986-acre Bobcat Fire burning in the Angeles National Forest, according to fire officials.

“Crews will continue to prep and add additional depth to secure lines north of Mt. Wilson and in the Northeast between Highway 2 and Big Rock Creek,” according an InciWeb news statement. “These continued strategic firing operations are done to secure the fires perimeter from the fire making a run at the fire lines from unburned fuels within.”
“Crew, engines, equipment and aircraft work in coordination to build holding lines, plumb the lines with water, and while firing aviation assets slow the movement of the main fire,'' according to the statement. “West of (Mount) Waterman, firefighters will continue to focus on strengthening the lines, where the Mt. Wilson operation occurred. A focus of our efforts (Friday and Saturday) will be securing the west side of the fire before winds shift to the northeast Sunday.”

U.S. Forest Service officials are investigating an equipment issue experienced by Southern California Edison around the time the fire broke out to determine if it was a factor in sparking one of the largest wildfires in Los Angeles County history.
Firefighters earlier this week successfully set backfires, including from the air, to destroy vegetation fueling the blaze and protect the Mount Wilson Observatory and several broadcast and telecommunications towers.
The fire is burning in the Angeles National Forest and threatening communities in the Antelope Valley and San Gabriel Valley foothills.
