Several wildfires erupted across Southern California on Thursday, prompting authorities to evacuate hundreds of homes in one community and shutting down a stretch of a major interstate highway.

A 450-acre fire raced through the Reche Canyon area toward a mobile home park in San Bernardino County, east of Los Angeles, forcing the evacuation of 200 homes, said county fire spokeswoman Tracey Martinez. Evacuation orders were later lifted.

More than 250 firefighting personnel responded along with two helicopters and two air tankers, Martinez said. The cause was under investigation.

A 100-plus acre fire burned in a canyon west of Los Angeles, but no homes were immediately threatened, authorities said.

Among the other fires was one that swept through hills north of Los Angeles in the afternoon, closing southbound Interstate 5, threatening some homes and an elementary school, and charring close to 30 acres before being doused.
