Windsor Fire Chief Jack Piccinini said that almost every one of Sonoma County's fire resources is being used, but it is not enough.
"These fires have destroyed structures and continue to threaten thousands of homes, necessitating the evacuation of thousands of residents", the proclamation said.
Belia Ramos, chairwoman of the Napa County Board of Supervisors, said officials did not yet have a count on how many properties were affected, either by the fire directly or by evacuations.
Mandatory evacuation were for homes on Atlas Peak Road, including Silverado Country Club; Knights Valley to Tubbs Lane in Calistoga; Partrick Road; Monticello Road to Circle Oaks Subdivision; the Montecito area of Napa and Soda Canyon Road.
The only positive news is that fire officials have said that the high winds of last night have died down for the time being, but they are expected to kick up again around sundown, meaning that fast containment is vital.

Patients at Kaiser Hospital in Santa Rosa were being removed early Monday morning, according to NBC Bay Area reporter Laura Garcia.
