The Powerhouse Fire exploded to at least 19,500 acres overnight Sunday, destroying at least six homes and forcing more evacuations north of Los Angeles.
As of Saturday afternoon, the fire had burned just 3,600 acres, according to the Los Angeles Times.
Erratic winds fanned the flames amid hot, dry conditions.

Nearly 1,000 homes in two foothills communities had to be evacuated, and a local fire station was surrounded by flames at one point.
"Driving away, you could see the town burning up," area resident Patty Robitaille, 61, told the Times. "I don’t think there’s going to be much left."
Three injuries were reported due to the fire, which was just 20 percent contained on Sunday.
