The latest on wildfires barreling through drought-wracked California (All times local):
8:40 a.m.
California Gov. Jerry Brown has declared a state of emergency in Lake and Napa Counties after a wildfire charred more than 60 square miles within 12 hours, prompting thousands to flee their homes.
Brown said Sunday the declaration will expedite debris removal and waive fees to people who need to replace official documents lost in the fire.
The blaze, about 100 miles north of San Francisco, has destroyed an unconfirmed number of homes and other buildings and damaged highways and other infrastructure.
Brown had earlier declared a state of emergency for a separate 101-square-mile wildfire about 70 miles southeast of Sacramento that has destroyed 86 homes.

Firefighters have made gains in their efforts to corral a 101-square-mile wildfire about 70 miles southeast of Sacramento, California.
More than 4,000 firefighters are working to beat back the flames and crews increased containment to 20 percent by early Sunday. Mandatory evacuations remain in place.
The fire, which broke out on Wednesday, destroyed 86 homes, 51 outbuildings and was threatening about 6,400 more. Teams had arrived by Sunday to assess the damage.
Authorities say the dry conditions, steep terrain and limited access to the flames are making for a challenging firefight.
7 a.m.
The destructive wildfire roaring through Northern California's parched Lake County has surged ahead, churning through an extra 23 square miles overnight.
California Department of Forestry and Fire Protection spokesman Daniel Berlant tweeted Sunday morning that the fire has burned up 62 1/2 square miles.
Authorities say the fire erupted in Lake County, about 100 miles north of San Francisco, Saturday afternoon and rapidly chewed through brush and trees parched from several years of drought.
An unconfirmed number of structures were destroyed. Entire towns as well as residents along a 35-mile stretch of highway were evacuated.
Four firefighters suffered second-degree burns in fighting the blaze and are hospitalized in stable condition.
