More than 31,000 people have been ordered to evacuate from the Hughes Fire, and another 23,000 are under evacuation warnings, LA County Sheriff Robert Luna said. There were no reports of homes or other structures burned. Parts of Interstate 5 near the Hughes Fire that had been closed reopened Wednesday evening.

More than 50,000 people were under evacuation orders or warnings Wednesday as a huge and fast-moving wildfire swept through rugged mountains north of Los Angeles, but fire officials said a rapid ground and air assault was giving them the upper hand.

The Hughes Fire broke out late Wednesday morning and in less than a day had charred nearly 16 square miles of trees and brush near Lake Castaic.
