Instructions:

A Coastal Flood Advisory means that tidal overflow flooding is expected. Coastal residents in the warned area should be alert for rising water, and take appropriate action to protect life and property. A High Surf Warning 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 lift or roll logs which can injure or kill someone caught in their path.
