The California Department of Forestry and Fire Protection said in a statement that on Friday evening, the vehicle released burning carbon from its exhaust system, which sparked the fire in Cherry Valley, an unincorporated town about 75 miles east of Los Angeles. Anyone with any information on the vehicle is asked to contact authorities.
The blaze has spread across hillsides and up the side of Mount San Gorgonio, destroying one home and two outbuildings. Nearly 8,000 people have been evacuated, and so far, no injuries have been reported. There are more than 2,300 firefighters on the scene.
"Much of the fire activity is being driven by the record-low moisture content of the vegetation in the area combined with high temperatures and low relative humidity," fire officials said on Monday afternoon. "These conditions are contributing to active fire behavior both day and night." Catherine Garcia
The Apple fire in Riverside County, California, is still burning out of control, with fire authorities saying on Sunday that it is zero percent contained.
So far, the blaze has scorched more than 20,000 acres. It was first reported on Friday evening in Cherry Valley, about 75 miles east of Los Angeles, and is sweeping through rugged terrain and steep hillsides.
The Apple fire has created a "very large pyrocumulus cloud" that looks like a mushroom, Lisa Cox, fire information officer for the San Bernardino National Forest, told the Los Angeles Times. "And what happens is when those really thick fuels start ripping and burning in those canyons, it creates this incredible power. The fire actually — it doesn't even matter what the wind's doing at that point — it just creates its own weather."
Nearly 8,000 people have been evacuated, and there are more than 1,300 firefighters on the scene. The Apple fire is California's first major wildfire this year. Catherine Garcia
