Surf warnings issued in S. California MANHATTAN BEACH, Calif., Jan. 6 (UPI) -- Southern California surfers were urged to exercise caution Friday as a high surf advisory was put into effect, the National Weather Service said. The advisory for west-facing beaches from San Diego north through Ventura County will continue through Saturday as a large swell originating in the central Pacific Ocean creates high surf and dangerous rip currents. Minor coastal flooding was expected Saturday morning during high tide. Surf heights of 6 to 10 feet were expected, with some sets as high as 12 feet in San Diego and Orange counties, meteorologists said. Ventura and Los Angeles County beaches will see surf heights of 6 to 12 feet, with some 14 foot sets possible. "Inexperienced surfers and swimmers should stay out of the water," the National Weather Service said. Those who wish to enter the water should only do so when lifeguards are present.
