Southern California warns residents as fires rage

Fanned by gusting winds, wildfires raged in densely populated Southern California for a fourth day on Thursday, with a new blaze north of San Diego exploding in size in just a few hours and dangerous conditions forecast until Sunday.

The blazes destroyed hundreds of houses and forced many Los Angeles-area schools to close. Flames hopscotched over highways and railroad tracks, and residents rushed to evacuate their homes with only minutes' warning, some leaving behind holiday gifts. People feared for the safety of animals from cats to llamas.

About 200,000 residents were evacuated from their homes at one point, though some were due to return on Thursday evening.

Authorities said the four biggest fires -- ranging from Los Angeles up the Pacific coast to Santa Barbara County -- were whipped up by the region's notorious westward Santa Ana winds that could reach hurricane strength.

The winds blow in hot and dry from the California desert, and the state CAL FIRE agency said gusty winds and extremely low humidity would continue through Sunday.

"Prepare now to ensure if evacuated you and your family are ready to GO!" CAL FIRE said on Twitter.
