SAN DIEGO - Elevated surf expected along the San Diego County coast later Saturday could lead to hazardous rip currents and minor beach erosion, forecasters said.

Lifeguards told 10News surf of mostly between 4 and 6 feet was expected on exposed west-facing beaches with local set of up to 8 feet south of Del Mar. 

"A long period swell generated by a storm off the coast of Japan will arrive in the Southern California coastal waters around sunset today and continue through Monday," a National Weather Service advisory said. "This will result in elevated surf heights and stronger and more persistent rip currents."

The rip currents could endanger swimmers, forecasters said. Minor beach erosion could also be possible.

The highest surf was forecast for Sunday and should gradually lower Monday through Wednesday, the NWS advisory said.
