California firefighters, helped by aircraft, battled a wind-driven wildfire that continued not only burning but spreading on Sunday, in an area straddling the San Francisco Bay Area and central California, authorities said.

The Corral Fire began on Saturday near the city of Tracy, 60 miles east of San Francisco, and the Lawrence Livermore National Laboratory in the city of Livermore, according to the California Department of Forestry and Fire Protection, or Cal Fire.
