Approximately 180,000 people have been ordered to leave their homes across much of northern Sonoma County as authorities worry that the Kincade Fire could grow quickly from powerful winds.
The area west of Fulton Road, south to Marin County, must also be emptied, authorities have said.
Authorities have also said Sebastopol, Bloomfield, and Valley Ford must be cleared.
The Kincade Fire, which started near Geyserville, has burned 30,000 acres, according to Cal Fire. The fire is 10% contained.
Flames have destroyed 79 buildings, but authorities consider 31,000 structures to be threatened by the Kincade Fire.
The Sonoma County Fairgrounds is now the only evacuation center still accepting people who've been ordered to leave their homes.
People who found shelter at the Finley Community Center in Santa Rosa have since been ordered to evacuate.
Earlier evacuation orders had been issued for Geyserville, Knights Valley, Healdsburg, Windsor, Dry Creek Valley, Mark West, Larkfield, Wikiup, Forestville, Guerneville, Duncans Mills, Jenner, Bodega Bay, and Occidental.
PG&E has cut power to nearly 1 million customers in an attempt to reduce the chance of additional fires. Damaged power equipment during wind storms and hot, dry weather has ben blamed for starting previous wildfires.
