Pacific Coast Highway reopened Monday morning, but authorities warned drivers using the route to expect delays. As of 8 a.m., motorists could again use Highway 1 through the cities of Los Angeles, Santa Monica and Malibu, according to a news release from the California Department of Transportation.

The second in a pair of back-to-back storm systems moved across Southern California overnight, triggering small mudslides in the Palisades Fire burn area and keeping public works crews and first responders on alert.

The stretch of the highway along the Pacific Ocean between Santa Monica and Malibu reopened to regular traffic. Some local officials believe it is too soon.
