Hundreds of thousands of people are expected to flee the state as California prepares to enter its third wildfire season in two decades.
Authorities said Tuesday that the latest wildfire was on the edge of the Sierra Nevada, which is the third-largest state in the country.
The California Department of Forestry and Fire Protection (CalFire) said more than 2,500 firefighters are battling the blaze in the San Joaquin Valley, which stretches from Sacramento in the east to Bakersfield in the west.
More: The state of emergency is in effect for five counties in the state, including the Sacramento-San Joaquin Delta.
CalFire said more restrictions are in place in the western Sacramento area, including restrictions on camping, fishing and the use of motorized vehicles.
The California Department for Natural Resources (CNR) said the number of evacuations was expected to increase from about 50,000 at the start of the fire season to more than 600,000 by Tuesday morning.
Cal Fire said about 6,600 structures are under evacuation orders.
The fire has forced thousands of evacuees to camp on public lands, some of them in remote areas, where they are living in tents or other temporary structures.
The state’s National Guard has been on standby for a possible response to the fires, but has not been deployed, said the California Department on Fire Service (CDFS).
It was the second time in two years that the state has been under a state of threat from a wildfire.
In February, the fire was reported in the Napa and Sonoma counties.
The first was in the Sacramento region.
California Governor Jerry Brown declared a state emergency on June 26 and ordered the state’s fire departments to prepare for an influx of evacuators from the wildfires.
