Hurricane Inundation by Evacuation Zone (Map) | NYC Open Data

These inundation areas are based on the National Hurricane Center’s 2020 SLOSH (Sea Lake and Overland Surge from Hurricanes) Model for the NE1 basin post-processed to a 10 meter resolution. The data used assumes that the storm surge will occur at high tide. The Storm surge inundation data then used to develop New York City’s Hurricane Evacuation Zones.
