The fire threat remains critical in Southern California, where thousands of residents were under evacuation orders Wednesday as fire crews battled the out-of-control Hughes Fire near Castaic, a suburb in the foothills and mountains of northern Los Angeles County.

The Hughes Fire grew rapidly near Castaic Lake, about 45 miles northwest of the city of Los Angeles, after it broke out at around 10.53am PST on Wednesday. No homes or businesses have been damaged, but about 31,000 residents have been forced to flee, officials said, with thousands more under evacuation warnings.
