A series of brush fires that ignited Wednesday in and around the eastern portions of Alameda and Contra Costa counties have burned down one home and torched roughly 500 acres, Cal Fire said Thursday.
The seven wind-whipped blazes known collectively as the Grant Fire ignited in the area near Mountain House and Grant Line roads, according to Cal Fire. The agency stated the blazes are 80 percent contained as of Thursday morning.
At one location, flames wiped out a home, an outbuilding, some cars, a trailer and a boat. Cal Fire has no reason to believe that anyone on the property was injured by the fire.
Fire crews on Thursday will continue to keep an eye on the gusty winds that initially fanned the flames. Barring any surprises, Cal Fire expects to have the fires fully contained by Thursday evening.
Cal Fire is still trying to figure out what exactly sparked the blazes. Officials will be looking into whether wind carried embers from the initial fire and sparked subsequent blazes.
