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.

Don’t be fooled by an ocean that looks calm. There can be 30 minutes of small waves before a sneaker wave strikes. Avoid rocks and jetties. Avoid steep beaches. Stay much farther back from the water and never turn your back on the ocean.
