Blaze just 5 percent contained

More than 40 square miles charred in gigantic Calif. wildfire

BANNING, Calif. — A wildfire in mountains east of Los Angeles that has forced thousands of people from their homes was sparked by a malfunctioning diesel vehicle, fire officials said Monday.

The vehicle spewed burning carbon from its exhaust system, igniting several fires Friday on Oak Glen Road in Cherry Valley, and authorities were asking anyone who may have seen such a vehicle at the time to contact investigators, according to a statement from the California Department of Forestry and Fire Protection.

The blaze in Riverside County, among several wildfires across California, had consumed more than 41 square miles of dry brush and timber since it broke out Friday evening, fire officials said.

As of Monday afternoon, it was just 5 percent contained and the fire along with coronavirus precautions made for added stress at an evacuation center, said John Medina, an American Red Cross spokesman.

The blaze began as two adjacent fires in a rural area near the city of Beaumont, about 85 miles east of downtown Los Angeles.

Flames raced along brushy ridge tops and came close to houses while firefighters attacked from the ground and air.

One home and two outbuildings were destroyed, California fire officials said. No injuries were reported.

In Northern California, evacuations were ordered after a wildfire that sparked Sunday afternoon spread quickly and burned near homes near the East Park Reservoir in Colusa County. Complicating firefighters’ efforts were temperatures in the area north of Sacramento climbed to 98 degrees by Monday afternoon. The fire was 40 percent contained.

On California’s central coast, a fire in San Luis Obispo County was 60 percent contained Monday after burning more than 2 square miles of brush east of the community of Santa Margarita. Two structures were destroyed but officials said it was unclear whether they were homes.

In Riverside County, officials allowed flames from the Apple Fire to run up the side of Mount San Gorgonio, an 11,000-foot peak, because it wasn’t safe to let crews work in such steep, rugged terrain, said Lisa Cox, a spokeswoman for the U.S. Forest Service.

Evacuation orders and advisories were issued for about 2,500 homes in mountain, canyon and foothill neighborhoods. Campgrounds and hiking trails were closed in the San Gorgonio Wilderness area of the San Bernardino National Forest.

A smoke plume was visible for miles around and contributed to poor air quality.
