More than 1,000 firefighters are working to contain the Valley Fire that ignited on Saturday afternoon near Cobb, California, located north of San Francisco.
The blaze, which has already scorched 50,000 acres, is zero percent contained as of Sunday night, according to Cal Fire. The towns of Cobb, Middletown and Hidden Valley Lake are some of the towns that have been hit by this fire.
Governor Edmund Brown declared a state of emergency for Lake and Napa counties with mandatory evacuations also issued for portions of these counties.

"In some cases, residents only had minutes to evacuate," Cal Fire said during a fire situation report on Sunday afternoon.
During the report, they added that the Valley Fire has destroyed countless homes and other buildings and they haven't been able to get an accurate count due to how fast the fire has spread.
People in the area should prepare to leave their homes, even if they are not currently under mandatory evacuation orders.
A shift in the winds can change the direction that the flames are advancing, putting new areas in danger of being burned.
Cal Fire added that four firefighters suffered from burn injuries on Saturday during the initial attack of containing the fire.

Fortunately, these injuries were not life threatening and the firefighters are expected to make a full recovery.
There is a report of a fatality due to the fire, according to Cal Fire's Chief of Public Information Daniel Berlant. This is being confirmed with the sheriff's office.
The weather has played a major role in how quickly the Valley Fire has spread.
Last week, the region experienced intense heat, topping out in the triple digits on some days. This heat allowed the brush and trees to become tinder dry, making it easier for them to catch fire.

This heat has subsided with temperatures falling back to levels more typical for the middle of September.
"Monday looks to be cooler, however, this is not necessarily a good thing," AccuWeather Meteorologist Evan Duffey said. "Cold fronts can bring chaotic and increased winds and early next week incident mangers may have a difficult time placing resources."
Duffey added that the increased winds can also help spread the fires and can lead to spot fires, when the winds carries burning material away from the main fire and into a new area.
Wind speeds will decrease by late week while temperatures are expected to rise.
The cause of the wildfire remains under investigation.
