A Southern California wildfire grew to more than 4,000 acres Friday night, destroying at least six structures with 10 percent containment, the Los Angeles County Sheriff’s Department confirmed in an update.

More than 1,300 firefighters remained in Santa Clarita, north of Los Angeles, as low humidity, high winds and temperatures threaten to spread the fire more.

The wildfire started Thursday afternoon and by Friday evening some evacuated residents were able to return to their homes.
