These large waves can be erratic and unpredictable. Use extra caution near the surf zone as these large waves will be capable of sweeping people into the frigid and turbulent ocean water. Mariners traversing the bar are urged to exercise extreme caution or stay in port until the threat subsides. This surf will also likely contribute to localized coastal flooding. Please contact the U.S. Coast Guard for information regarding harbor and bar closures. PRECAUTIONARY/PREPAREDNESS ACTIONS... A High Surf Warning indicates that dangerous, battering waves will pound the shoreline resulting in beach erosion. Stay far back from the surf and do not enter areas flooded by the waves. && $$
