The 5-acre blaze broke out at around 3:40 a.m. off Santiago Canyon Road, just south of the 241 Freeway interchange. According to California Highway Patrol’s incident information page, it appears to have started after a car slammed into a telephone pole and caught fire. It’s unclear if anyone was hurt in the wreck.

Santiago Canyon Road was shut down between the 241 Freeway south to Loma Ridge Road. No structures were threatened and there was no word of any evacuations.
