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.

Thousands of Southern California residents were under evacuation orders Wednesday as fire crews battled the out-of-control Hughes Fire near the town of Castaic, a suburb in the foothills and mountains of northern Los Angeles County.

The Hughes Fire has spread over 8,096 acres after starting just before lunchtime in Los Angeles County's Castaic Lake area on Wednesday.

Forecasters warn that dangerous winds will buffet Southern California for at least two more days as new wildfires broke out and a pair of major Los Angeles-area blazes burned for a third week.

A new fast-moving wildfire has erupted in Los Angeles County, triggering evacuations in a region already reeling from the most destructive fires in its history. The Hughes fire ignited north of the city on Wednesday afternoon, near Castaic Lake in a mountainous area that borders several residential areas and schools.
