San Francisco residents were awakened Monday to the smell of smoke coming from fires in Napa and Sonoma counties.
Tens of thousands of acres have burned in multiple wildfires in Napa County, Cal Fire officials said.
The Tubbs Fire, reported in the area of state Highway 128 and Bennett Lane in the Calistoga area, has burned about 35,000 acres, officials said at a 9 a.m. news conference.
The Atlas Fire, initially reported at 9:20 p.m. Sunday, had burned between 8,000 to 12,000 acres south of Lake Berryessa and off of Atlas Peak Road, according to Cal Fire. The blaze was 0 percent contained as of 9 a.m.
A Red Flag Warning was in effect for strong and dry north winds, weather officials said.
