- Evacuation orders have been issued after a wind-fueled wildfire ignited Friday in a Southern California coastal community, burning through homes and 465 acres, fire authorities said. The fire started in vegetation in San Clemente, and strong winds quickly pushed it into neighboring San Juan Capistrano in Orange County. Fire authorities received a report at 11:33 a.m. Friday. The blaze grew to cover an area equal to about 350 football fields by 5 p.m., according to fire authorities. "We rapidly launched an assault of air and ground resources to head towards this fire," Orange County Fire Authority Division Fire Chief Mark Backoff said in an update on social media.

Homes were quickly engulfed as firefighters attacked the flames to stop them from jumping to the next house. One firefighter was overcome with heat exhaustion fighting the fire, Backoff said. The department had prepared for the wind event, placing equipment in the area before the fire started, Backoff said.

The Santa Ana Winds also fueled last year's deadly and destructive Palisades and Eaton fires in Los Angeles County. Orange County and San Diego County coastal areas were under a heat advisory Friday as temperatures were expected to reach the mid-90s in some cities. Meanwhile, on Wednesday and Thursday, Gov.
