At least 23 people have died and at least 1,500 homes have been destroyed as disastrous fire sweeps throughout Northern California on Monday, authorities said.
The state's fire chief called the damage estimates for the fire in the wine country conservative and said the fires were burning throughout an eight-county swath of Northern California, including Napa, Sonoma and Yuba counties.
Numerous people had been hurt and some were missing, although no estimates were immediately available, said California Department of Forestry and Fire Protection Director Ken Pimlott. Later he said there were likely fatalities.
Mandatory evacuations were ordered after the blazes broke out late Sunday. Long lines formed at gas stations when many families heeded a middle-of-the-night call to get out. A spokesperson for Pacific Gas & Electric said 114,000 customers were without power.
"It was an inferno like you've never seen before," said Marian Williams, who caravanned with neighbours before dawn as one of the wildfires reached the vineyards and ridges at her small Sonoma County town of Kenwood.
Williams could feel the heat of her fire through the car as she fled. "Trees were on fire like torches," she said. With downed trees or flames blocking routes, Sonoma County residents struggled to figure out what roads to take.
Fires also burned just to the east in the Napa County as well as in Yuba, Butte and Nevada counties all north of the state capital. Many of the fires spread suddenly overnight, whipped by furious winds.
Santa Rosa, the largest city in the fire area with a population of about 175,000, was hit hard. The city lost a Kmart and unknown numbers of other businesses and homes, as the blaze shut down its schools and forced patients at two city hospitals to evacuate. A Hilton Hotel was smoldering and in ruins.
"Imagine a wind-whipped fire burning at explosive rates. This is 50 miles per hour. Literally it's burning into the city of Santa Rosa ... burning box stores," Pimlott said. "This is traditionally California's worst time for fires, California's most damaging times for fires have occurred in October."
More than 200 people were hurriedly evacuated from Sutter Santa Rosa Regional Hospital and Santa Rosa Medical Center, where the blaze could be seen raging nearby.
Napa County Fire Chief Barry Biermann said the fires had burned more than 68 square miles (176 sq. kilometers). Crews had not yet been able to contain a fire heading toward downtown Napa.
