California ? Thousands of firefighters battled wildfires across California on Thursday, including a growing blaze that forced about 2,400 people to evacuate their homes in the Santa Cruz Mountains.

The Lockheed Fire, which started around 7 p.m. Wednesday, had scorched about 2,800 acres, or 4.4 square miles, in Santa Cruz County, according to the California Department of Forestry and Fire Protection.

The blaze, about 10 miles north of the coastal city of Santa Cruz, threatened more than 1,000 homes and other buildings and was not contained by late Thursday.

Authorities issued a mandatory evacuation order Thursday for the entire community of Bonny Doon, which has about 2,000 residents and several wineries, but CalFire spokesman Mike Mohler said there have been no reports of any homes destroyed or other structures burned.

Everyone also has been ordered to leave the nearby community of Swanton, where about 400 people live.
