SAN BERNARDINO (CBS/AP) — A fire official says more than 82,000 people have been told to evacuate from mountain communities threatened by a powerful wildfire in Southern California.

San Bernardino County fire spokesman Eric Sherwin says the evacuation orders were given to about 34,500 homes.

Sherwin says some structures have already burned, but it hasn’t yet been determined whether any of them were homes.

As of Tuesday night, the fire, dubbed the Blue Cut Fire near Cajon (kuh-HOHN’) Pass has spread to 15,000 acres, according to Cal Fire.

The 14-square-mile Blue Cut Fire has seen massive growth in the eight hours since it broke out on Tuesday morning.
