Description:
* WHAT...For the High Surf Warning, dangerously large breaking
waves of 30 to 40 feet, with largest wave sets up to 60 feet
at favored spots. For the Coastal Flood Warning, coastal
flooding in low lying areas.
* WHERE...San Francisco, Coastal North Bay Including Point Reyes
National Seashore, San Francisco Peninsula Coast, Northern

Counties.
* WHEN...For the High Surf Warning, until 6 PM PST Tuesday. For
the Coastal Flood Warning, until noon PST Tuesday.
* IMPACTS...Life-threatening swimming and surfing conditions and
significant shoreline erosion can be expected. Numerous roads
may be closed, and sand berms over-topped. 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.
Instruction:
Take the necessary actions to protect flood-prone property. If
travel is required, do not drive around barricades or through
water of unknown depth.
Everyone should remain out of the water due to life-threatening
surf conditions. Stay off of jetties, piers, and other waterside
infrastructure.
