A fast-moving wildfire exploded to roughly 10,200 acres near the Los Angeles County community of Castaic Wednesday morning, prompting mandatory evacuation orders and road closures, authorities said.

Firefighters continue to make progress in containing the massive Hughes Fire that broke out Wednesday near Castaic Lake, growing to more than 10,000 acres and forcing mass evacuations. Around 38,000 people remain under evacuation warnings even as containment has reached 36%.

A fire north of a jail complex in Castaic has triggered evacuations in L.A. County, even as Southern California hopes for some rain to help with firefighting efforts.
