This map shows the areas most vulnerable to sea-level rise. As you can see, much of coastal Carolina is highly vulnerable.


As explained on the “What is a King Tide?” page, king tides are natural phenomenon that occur because of the changing gravitational pull of the moon and sun on the Earth.

King tides are not caused by climate change or sea-level rise. However, they can serve as a tool to help us to better understand what normal tides could look like under sea-level conditions in the future.

It is quite possible that in the future, “normal” high tides will reach the magnitude of today’s king tides. In other words, the flooding we see during king tide events could become a regular occurrence in the future. This phenomenon has serious implications for coastal residents who experience nuisance flooding and worse, as well as for disaster preparedness and management.
