The advisory covers the coastal regions of Ventura, Los Angeles and San Diego counties, Catalina and Santa Barbara islands. The advisory is slated to expire at 10 p.m. Tuesday.
According to the National Weather Service, 8-12 foot surf was expected across west facing beaches, peaking Monday afternoon through Tuesday morning. Local sets to 15 feet will be possible near Ventura Harbor.
The conditions mean stronger rip currents, which raises the risk for drowning.
