* WHAT…Large northwest swell will result in breaking waves of 20
to 25 feet along north and west facing beaches.
* WHERE…Coastal San Francisco, Coastal North Bay Including
Point Reyes National Seashore, San Francisco Peninsula Coast and
Southern Monterey Bay and Big Sur Coast.
* WHEN…Until 4 AM PST Wednesday.
* IMPACTS…Dangerous swimming and surfing conditions and
localized beach erosion. Sneaker waves can unexpectedly run
significantly farther up the beach than normal, including over
rocks and jetties. These waves can suddenly knock people off
their feet and quickly pull them into the cold ocean waters,
where currents will be stronger than normal. These waves can
also carry driftwood logs and other debris.
