In just 12 hours, 14 different fires have spread across Northern California killing at least 15 people and injuring at least 100 others.
Over 2,000 homes and businesses have already been destroyed.
One Anaheim resident who lost home told the Associated Press, "I was trying to spray the backyard as much as I could, but within minutes, I saw the fire coming up over the hill there, and I was like, I have to get out of here."
Two hospitals and a senior living center have also been forced to evacuate.
More than 91,000 people are currently without power.
In Bakersfield at least two dozen horses have been killed in the fires.
According to CNN, it could take days before the fires are contained.
According to authorities, the firestorm ripping through Northern California’s wine country is among worst in state's history. The fire started Sunday night and so far at least ten people have died.
Over 20,000 people have been forced to evacuate and more than 1,500 homes and commercial structures have been destroyed. During a press conference on Monday, California Fire Director Ken Pimlott said the biggest fires are burning in Napa Valley.
Gov. Jerry Brown has declared a state of emergency in Napa, Sonoma and Yuba counties.
Fire officials said Monday that the fires show no sign of ending amid high winds and dry weather.
Complicating firefighting efforts are low humidity and a lack of resources, Napa County Fire Chief Barry Biermann said.
"As of right now, with these conditions, we can't get in front of this fire and do anything about the forward progress," he said, adding that resources from across California were to begin arriving in the area later Monday.
The cause of the fires is still under investigation.
