A brush fire in the Antelope Valley near the Los Angeles and San Bernardino County line was at 2,690 acres with no further growth expected, firefighters said Tuesday.
The Summit Fire was 53% contained after it was initially reported at around 12:50 p.m. Friday near Jesus Canyon Road and East Avenue Z in the Llano area west of Piñon Hills, according to Cal Fire’s latest update Tuesday morning.
“Firefighters continue making progress building control lines and putting out hot spots,” Cal Fire reported Monday evening. “Interior pockets of the Summit Fire continue to burn while larger fuels smolder and produce visible smoke. Heavy annual rainfall has created a dense fuel bed, and recent winds, high temperatures and low relative humidities have rapidly dried out thinner, smaller fuels, creating a highly receptive fuel bed.”
Officials said crews are operating in steep, rocky terrain, and narrow roads present additional driving hazards.
An extreme heat warning takes effect Tuesday morning through Thursday evening, according to the National Weather Service.
Triple-digit temperatures increase the risk of heat-related illness for ground crews fighting the blaze, officials said.
“Operational priorities will focus on maintaining strict safety protocols amidst the intense heat while monitoring for potential thunderstorm development,” Cal Fire reported at 6:16 p.m. Monday. “Crews will remain vigilant for erratic outflow winds and dry lightning, which could cause unpredictable fire behavior, while continuing to navigate the hazards of steep terrain and rolling debris.
“Crews will continue strengthening control lines and mopping up hot spots,” the Cal Fire statement added. “They will also identify secondary control line locations.”
Forward progress was stopped at 2,690 acres Sunday as containment grew to 31% and the single evacuation order was lifted after being in effect for the area near East Avenue Z and Fort Tejon Road. Evacuation warnings were issued in other nearby locations as the fire spread into the Angeles National Forest toward San Bernardino County.
Evacuation warnings remained Tuesday for two areas between Angeles Crest Highway and state Route 138 on the eastern edge of LA County, west of Piñon Hills.
“This cautious approach ensures public and crew safety amid incoming winds, potential interior fire behavior, and a heavy presence of emergency vehicles,” according to Cal Fire.
“While all evacuation orders were downgraded Sunday and no further fire growth is expected, active winds mean residents may still see localized smoke and brief interior flare-ups well within the established burn area,” Cal Fire’s statement added.
Cal Fire inspection teams have completed about 90% of damage assessments, officials said.
The fire has destroyed two structures, damaged five and caused one firefighter injury, the agency reported.
As of Tuesday morning, 1,060 firefighters were battling the blaze, according to the Los Angeles County Fire Department. Cal Fire reported 74 engines, five dozers and 11 water tenders were involved in the firefight.
Officials are investigating the fire’s cause.
