Event:
High Surf Warning
Urgency:
Expected
Effective:
December 22, 2024 - 6:15pm
Expires:
December 23, 2024 - 5:00am
Description:
* WHAT...For the Coastal Flood Warning, significant coastal
flooding expected. For the High Surf Warning, dangerously large
breaking waves of 30 to 35 feet, including breakers up to 40
feet at favored spots such as Mavericks.
* 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 noon PST Tuesday.
* IMPACTS...Life-threatening swimming and surfing conditions and
significant shoreline erosion can be expected. Numerous roads
may be closed, and some critical infrastructure will be
inundated. 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.
