From NWS:
…INCREASED RISK OF SNEAKER WAVES LATE TONIGHT THROUGH LATE
FRIDAY NIGHT…
A long period west-northwest swell will impact the coastline from Sonoma southward through Big Sur beginning late tonight.
Forerunner waves will arrive late this evening but the greatest risk of sneaker waves impacting the coast will exist from late
tonight through late Friday night. These sneaker waves will be infrequent waves powerful enough to knock unsuspecting people into
the ocean during otherwise deceptively light seas.
The National Weather Service in San Francisco has issued a Beach Hazards Statement for increased sneaker wave risk, which is in
effect from late tonight through late Friday night.
* HAZARDS…Increased sneaker wave risk.
* TIMING…From 4 AM Friday to 4 AM Saturday.
* LOCATION…Entire Pacific coastline from Sonoma south to Big
Sur.
* POTENTIAL IMPACTS…Larger surf at offshore breaks and an enhanced risk of sneaker waves on northwest California beaches.
Steep beaches will have a higher risk of sneaker wave activity with greater wave run-up onto beaches. Large waves will also
wash over jetties and rock outcroppings that may normally stay dry.
A Beach Hazard Statement for sneaker waves means that conditions are present to support a heightened risk of unsuspecting beach
goers being swept into the sea by a wave. People walking along the beach should never turn their back to the sea. Fisherman should
avoid fishing from rocks or jetties.
