1,200 Evacuated as Wildfire Spreads North of Los Angeles

About 1,200 people were evacuated from a California state park after a wildfire erupted near a major highway about 60 miles northwest of Los Angeles.

The blaze was burning out of control and covered 11,000 acres as of Sunday morning, according to an update from the California Department of Forestry and Fire Protection, known as Cal Fire.

"Currently crews are working to construct perimeter fire lines around the flakes of the fire," Cal Fire said on its website. "Aircraft are working to stop forward progress but have limited visibility."

The flames broke out around 1:45 Saturday in Gorman, California, an area along Interstate 5, which stretches the length of the state and connects cities including San Diego, Los Angeles and the state capital of Sacramento.

Authorities haven't yet determined the cause.

The blaze, dubbed the Post Fire, prompted workers to clear out the nearby Hungry Valley park, which features 130 miles of trails for off-road vehicles.

The fire was moving southeast toward Pyramid Lake, where a recreation area was closed as a precaution, Cal Fire said.

The weather forecast called for slightly higher temperatures and lower humidity, and Cal Fire warned residents to "remain vigilant and be prepared to evacuate if fire activity changes."
