A Coastal Flood Watch means that conditions favorable for flooding are expected to develop. Coastal residents should be alert for later statements or warnings, and take action to protect 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.
