California's newest wildfire tore through retirement communities built on golf courses and killed elite thoroughbred horses in its first destructive day. The new blaze, in San Diego County, means a huge swath of Southern California is now in flames. December's shockingly dry, hot and windy conditions brought on unprecedented fire danger.

The San Diego-area fire quickly grew to more than 6 square miles and burned dozens of homes at Rancho Monserate Country Club. Flames engulfed a horse training center, prompting trainers to unlock stables and encourage hundreds of race horses to run for their lives. It's not clear how many died.

The destructive blaze broke out as firefighters tried to corral the largest fire in the state, which was burning around Ventura - 130 miles to the north. It destroyed at least 439 buildings as it grew to 180 square miles since Monday. Fire crews also fought large fires around Los Angeles. The Ventura and L.A.-area fires put tens of thousands of people under evacuation orders.
