Authorities say a wildfire outside the scenic Big Sur region on California's Central Coast has destroyed 20 homes, up from six.
The California Department of Forestry and Fire Protection said Monday that the blaze has forced evacuations and is threatening 1,650 mountain homes in the region. No one has been injured.
More than 1,300 personnel are battling the 23-square-mile fire, which is burning mostly out of control in hard-to-reach terrain.
Fire officials advised residents of nearby communities to be prepared to leave immediately if a voluntary or mandatory evacuation order is issued. An evacuation center is open at a school in Carmel-By-The-Sea.
