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.

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.

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.

As the sun began to set over Castaic Lake on Wednesday, the hills to the north and east were engulfed in flames, casting an eerie orange glow across the valley below.
