INSTRUCTIONS

A Coastal Flood Advisory indicates that onshore winds and tides will combine to generate flooding of low areas along the shore.

Feet Above Ground is locally defined as feet above the Highest Astronomical Tide or HAT.

Large breaking waves along the coast will lead to increased wave run-up on beaches with waves topping and washing over large rocks and jetties. 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. Please contact the U.S. Coast Guard for information regarding harbor and bar closures.
