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.

Evacuation orders and warnings were issued to more than 31,000 people in the vicinity of two new wildfires north of Los Angeles on Wednesday.

Continued strong winds and dry conditions on Wednesday morning rapidly spread a fire near Castaic Lake in northern Los Angeles County and has burned through 8,096 acres.

Firefighters made progress on the more than 10,000-acre Hughes Fire Thursday, which sent thousands fleeing after sparking near the Los Angeles County community of Castaic a day earlier.
