Despite light vegetation to fuel it when it started, a brush fire in the Castaic area Saturday grew from an initial three acres to more than 3,000 acres in four hours, authorities said.
The fire — dubbed the Charlie Fire due to Charlie Canyon Road, where the blaze first was sighted — was reported at 2:40 p.m., according to Los Angeles County Fire Department Inspector Joey Marron.
The fire covered a few acres at the top of a ridge when firefighters arrived and sized it up at 2:44 p.m., Marron said.
They quickly called for a third-alarm response of 120 firefighters, aided by three helicopters and two super scooper fixed-wing aircraft, he said.
A strike team made entirely of 22 Los Angeles city firefighters was on scene along with a helicopter, spokesman Brian Humphrey said. A second strike team was being assembled with LAFD and allied agencies represented.
By 6 p.m. the Santa Clarita Valley sheriff’s station reported Lake Hughes Road was closed from Ridge Route to Dry Gulch and that Francisquito Canyon Road was closed and evacuated from Lowridge Place North to Camp 14. No homes were affected or being evacuated, the sheriff’s department said.
About 100 structures were threatened as the fire spread and 20 to 30 homes were evacuated, fire officials said. A shift in the wind was pushing the fire in a southernly direction.
The rough terrain was cited as a reason for the spread.
