Up to 1,500 buildings have been destroyed and hundreds of people evacuated from their homes in northern California, as well as hospitals and businesses, as a number of fires were raging the area, local media reported.
Three large fires were recorded in Napa County at dawn, said County spokeswoman Molly Rattigan. California state governor Jerry Brown has declared a state of emergency. Residents of the area were subjected to mandatory evacuations and sent to local shelters.
No deaths have been reported, there have been injuries, and people are unaccounted for, said Janet Upton, a spokeswoman for the California Department of Forestry and Fire Protection.
"This time of year is when historically the state’s largest, most damaging and most deadly fires have occurred," said Upton, referring to the strong autumn winds.
One of the most raging fires hit the town of Santa Rosa, Sonoma County, with a large swath of the city north of downtown under evacuation order and closed schools.
The National Weather Service issued a wind warning on Sunday and said it expected winds of 32 to 56 kilometers per hour.
