Hurricane Lee Assessment of Potential Coastal-Change Impacts: NHC Advisory 40, 0500 AM EDT FRI SEP 15 2023

This dataset defines storm-induced coastal erosion hazards for the New York, Rhode Island, Massachusetts, New Hampshire and Maine coastline. The analysis was based on a storm-impact scaling model that used observations of beach morphology combined with sophisticated hydrodynamic models to predict how the coast would respond to the direct landfall of Hurricane Lee in September 2023. Storm-induced water levels, due to both surge and waves, were compared to beach and dune elevations to determine the probabilities of three types of coastal change: collision (dune erosion), overwash, and inundation.
