Local media reports said mudslides and flooding shut down the Pacific Coast Highway in Malibu near the Los Angeles and Ventura County line on Saturday.
Rocks, branches and mud gushed over the major road and brought traffic to a halt, ABC7 said. No injuries have been reported.
Residents told the broadcaster the mud moved relentlessly and that they had to wade through several inches of the sludge to get to their homes.
The LA County Sherrif's Department issued a "mudslide alert" on Twitter on Sunday warning of road closures following heavy rain in the region.
