THE FOLLOWING ARE UNOFFICIAL OBSERVATIONS TAKEN DURING THE RECENT (Click panel for larger image Predictions represent the astronomical tide level Verified represent total storm tide) Battery The storm surge was calculated by subtracting the astronomical tide level from the maximum water level. The astronomical tide level was the predicted tide level for the time that the maximum water level was measured. For the purposes of the tables above, the maximum water level was the highest water level recorded at the designated gauge.The maximum water level, or storm tide, is the sum of the astronomical tide level and storm surge. ![]() Storm surge is defined as the abnormal rise of water generated by a storm, over and above the predicted astronomical tide.National Ocean Service (NOS) Gauges Location NGVD = National Geodetic Vertical Datum of 1929 Here is an EXAMPLE Inundation Map over portions of New York Cityįor more detailed information on inundation and storm surge, please see the full NHC Sandy Reportįor detailed surge data, please see the United States Geological Survey (USGS) Storm Surge Mapper The values are a reasonable worse cast scenario using storm surge values that have a 1 in 10 chance of being exceeded at each location. The data takes into account forecast uncertainty in the track, intensity, and wind field of the tropical cyclone. The maps show geographic areas where inundation from storm surge could occur, and the heights, above ground, that water could reach in those area. These maps were developed over the course of several years in consultation with social scientists, emergency managers, broadcast meteorologists, and others. A Potential Storm Surge Flooding Map is a new operational product that depicts the risk assoicated with coastal flooding from storm surge associated with tropical cyclones. Inundation Mapping and Interpretation: All storm surge forecasts are now given in water levels (in feet) above ground level in an effort to improve understanding and interpretation. ![]()
