State fire officials say they halted a wind-driven run of flames from spreading into the city of Sonoma.
Deputy state fire director Dave Teter said Saturday that a minimal number of structures were burned, but that no further damage was expected after firefighters stopped the advancing blaze.
On Friday, firefighters made progress against the wine country wildfires that have been burning since Sunday night. But they worry that gusty winds predicted for this weekend could fuel the flames and lead to more flare-ups.
The number of dead from the weeklong fires in Northern California remained at 35, and the number of destroyed homes stood at 5,700.
Authorities say about 100,000 people remain under evacuation orders as the wildfires burn for a sixth day. Flare-ups drove hundreds more to flee on Saturday.
Teter says plans are in the works to allow some evacuees to return to their homes, but they haven't been put in place yet.
With high winds and dry weather statewide, more fire crews and equipment such as helicopters are being staged in Southern California in preparation for any fires there.
Governor Jerry Brown and U.S. Senators Dianne Feinstein and Kamala Harris are set to visit the fire zones later Saturday.
They'll attend a community meeting Saturday afternoon in Santa Rosa, a city hit hard by the deadliest and most destructive series of wildfires in California history.
