A fire that broke out in Camp Pendleton has forced the evacuation of hospital and a military housing unit.

Base officials say the fire which broke out near Lake O'Neil Saturday afternoon prompted the evacuation of 230 residents at a nearby housing unit.

A power outage at Naval Hospital Camp Pendleton also prompted officials to transfer about 30 patients to other hospitals in the area.

The fire has burned about 250 acres, sending smoke that could be seen across northern San Diego County.

The cause of the fire and the power outage was under investigation.

Hot, dry and windy conditions fueled several small fires across Southern California, including one that caused a key freeway junction north of Los Angeles to shut down.
