A brush fire in Topanga Saturday burned an estimated four to five acres and was 80% contained as of 6:30 p.m., according to authorities.
The fire ignited near 1200 N. Topanga Canyon Blvd. just before 4 p.m., said Los Angeles County Fire Department Dispatch Supervisor Cheryl Sims. Forward progress of the blaze was stopped around 4:25 p.m., she added.
The blaze broke out in heavy, inaccessible brush, according to fire authorities.
Initially, Topanga Canyon Boulevard between Mulholland Drive and Pacific Coast Highway was closed to all traffic except emergency vehicles because of the brushfire, the sheriff’s department reported.
The California Highway Patrol issued a SigAlert at 4:13 p.m., and canceled it at 9:38 p.m., when they reopened Topanga Canyon Boulevard in both directions between Mulholland Drive and Pacific Coast Highway.
County fire supplied a full brush response, including water dropping helicopters, a strike team, engines and a water tender, according to the department. L.A. City Fire Department supplied eight engines and three water-dropping helicopters, fire department spokesman Brian Humphrey said.
Some firefighters were airlifted to the top of the ridge to fight the fire.
So far, no structures have been threatened and no injuries have been reported. No evacuation orders were issued by fire authorities.
A Red Flag warning will be in effect in the Santa Monica Mountains beginning 1 a.m. Sunday.
The cause of the fire remained under investigation.
