DAVENPORT, Calif. -- California residents in fire danger zones are being urged to follow orders to leave their homes.
Crews are struggling to control nearly a dozen wildfires burning in areas with inaccessible terrain.
A fire in Santa Cruz County has blackened more than 10 square miles of remote wilderness since Wednesday.
The fire is about 40 percent contained.
Meanwhile, a separate fire in Yuba County north of Sacramento has tripled in size to more than 6 square miles.
It's reported about 15 percent contained.
Farther north, the Santa Barbara County Sheriff's Department says that a week-old wildfire in the Los Padres National Forest was started by a campfire set by marijuana growers, part of a drug operation run by Mexican nationals.
The fire has burned 131 square miles of timber and brush in the forest about 140 miles northwest of Los Angeles.
It's about 25 percent contained.
