The conditions present an increased risk of ocean drowning, and the large waves can cause injury, wash people off beaches and rocks, and capsize small boats near shore, the weather service said. The hazards were to be most pronounced on northwest-facing beaches.
At 4 a.m. Friday, a Pt. Piedras Blancas Buoy reported a swell of 16 feet at 14 to 16 second periods, the weather service said. Other buoys along the central California coast were reporting 11- to 13-foot swell.
