Thousands of firefighters have been battling wildfires across 45 square miles of densely populated Los Angeles County. The two largest fires, the Palisades Fire in Pacific Palisades and the Eaton Fire near Pasadena, remain active. One of the latest, the Hughes Fire in the Castaic area, has prompted evacuation orders for tens of thousands of people.

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.
