* WHAT…For the HIGH SURF ADVISORY: Large breaking waves of 15 to
22 ft at a period of 14 to 18 seconds.
* WHERE…San Francisco, Coastal North Bay Including Point Reyes
National Seashore, San Francisco Peninsula Coast, Northern
Monterey Bay and Southern Monterey Bay and Big Sur Coast
Counties.
* WHEN…Until 6 PM PST Wednesday.
* IMPACTS…Hazardous swimming and surfing conditions and
significant shoreline erosion can be expected. Large waves can
sweep across the beach without warning, pulling people into the
sea from rocks, jetties and beaches. Sudden immersion in cold
water can result in cold water shock even for the most
experienced swimmers. Cold water shock can result in dramatic
changes in breathing, heart rate and blood pressure, greatly
increasing the risk of drowning in rough open waters.
