The flames from the “Mountain Fire,” which started in a rural area of the small unincorporated community of Somis in Ventura County, grew to about 1.5 square miles by noon Wednesday, the California Department of Forestry and Fire Protection (Cal Fire) said.
By about 11 a.m., the fire had crossed Highway 118 and was reaching homes in the Camarillo Heights area, according to Ventura County Fire Department.
Witnesses and media reported firefighters scrambling to save lives as flames threatened homes.
About 140 firefighters were on scene with 58 fire trucks, according to the department.
The cause of the fire, which reportedly started at the corner of Balcom Canyon and Bradley roads, was under investigation.
Evacuation orders were in effect for residents and businesses on Walnut Avenue to Balcom Canyon Road, north of Highway 118 to the ridgeline, and west to Saticoy Country Club, according to fire officials.
An evacuation shelter was opened at Padre Serra Paris, at 5205 Upland Road in Camarillo.
Camarillo is a city with nearly 70,000 residents, according to the U.S. Census Bureau. The community is located between Los Angeles and Santa Barbara. Camarillo Heights is a neighborhood with homes ranging in value from $300,000 to $3 million, according to online realty site Realtor.com.
Numerous homes were threatened by the growing flames, the department reported.
Because of extreme wind conditions, firefighters were not able to use fixed-wing firefighting aircraft to help extinguish or slow the fire’s growth.
“Ground crews, helicopters and mutual aid resources are actively working to protect lives and property,” the department reported.
The National Weather Service had placed Ventura County, along with several other California counties, under a red-flag warning starting earlier Wednesday. Dry conditions and gusty winds prompted the warning, which alerted residents to the high probability of fire danger in the area.
Red-flag warnings were issued to much of California on Wednesday as strong winds were expected from Napa and Sonoma counties down to San Diego County.
Weather forecasters were expecting low humidity, dry vegetation, and gusting winds for the next two days. When those factors are combined, California allows utilities to temporarily turn off power in some areas to reduce the risk of starting wildfires by overloading utility lines.
In Southern California, the winds were expected to sweep through the region until Thursday.
