California firefighters aided by aircraft battled a wind-driven wildfire that began Saturday and continued burning early Sunday morning in an area straddling the San Francisco Bay Area and central California, authorities said.
The Corral Fire began Saturday afternoon near the city of Tracy, 60 miles (96km ) 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.
Dark plumes of smoke traveled high into the sky over the fire area comprised mostly of grassy hills, where strong winds were expected to continue overnight.
On Sunday morning, Cal Fire announced that the fire had spanned 12,500 acres and was 15% contained. “Strong winds and dry grass have made it difficult to contain,” it added.
