PRECAUTIONARY/PREPAREDNESS ACTIONS…

A High Surf Advisory means that high surf will affect beaches,
producing rip currents, sneaker waves and beach erosion. Stay
well back from the water’s edge and be alert for exceptionally
high waves.

Keep away from large logs on the beach. Water running up on the
beach can easily lift or roll logs which can injure or kill
someone caught in their path.
