MALIBU, Calif. (KABC) -- Caltrans said Pacific Coast Highway would remain closed in both directions from Las Posas Road in Ventura County to Encinal Canyon Road in Malibu possibly through Tuesday.
Several vehicles were stuck in mud Sunday on PCH, where rain triggered debris flows the previous evening and forced the closure of a 13-mile stretch of the highway.
Maintenance crews at the scene continued to assist with towing and cleanup, but Monday morning's light showers caused concern over mud breaking loose.
Malibu residents, some of whom are survivors of the Woolsey Fire, described their reactions as boulders, rocks and tree limbs covered PCH in the mudslide.
"Last night I was full-on PTSD after what we experienced with the fire," said Jordan Jacob, who lost his home to the November wildfire. "It brought back a lot of feelings, like, oh no, we gotta go, we gotta be prepared.
"But we were pretty well-prepared," he added, "and we learned a lot from the fire that we are going to take on mudslide season."
