What
Minor to moderate coastal flooding expected due to very high tides.
Impacts
Minor to moderate flooding of sea water is likely over vulnerable low-lying coastal areas, especially around the time of high tide, including over beach parking lots, bike paths, and harbor walkways. Moderate to significant beach erosion is likely. Isolated damage of structures due to sea water inundation is possible.
