Adapting FIMP Ensembles and Results to the Present Study 
194. The present study area is located southwest of the FIMP area. 
Considering the relatively small spatial scale of hurricanes, it was necessary 
to alter the FIMP hurricane storm ensemble for use in the present study. All 
918 original synthetic storms were retained and one additional landfall point 
accompanied by a track angle was added. This additional storm track was pat- 
terned after the 1903 hurricane which made landfall near Barnegat Inlet on the 
south New Jersey coast. After these new LP- and TA-values were combined with 
the six DP, three FS, and three RM values from FIMP, an additional 54 synthe- 
tic hurricanes resulted. The additional 54 hurricanes were simulated on the 
FIMP global grid. The hurricane storm ensemble for the present project is 
shown in Table 11. Surge time-histories from a numerical gage located at 
Sandy Hook were used to create the hurricane surge plus tide ensemble for 
these 972 simulations.

#* The landfall point was defined as the distance in nautical miles from the 
origin of the numerical grid of this study (40°18' N, 74°06' W) to where the 
storm landed. 
195. Considering the relatively large spatial extent of northeasters, 
the 27 historical northeasters from FIMP were assumed to be adequate for the 
present study. The Sandy Hook tidal gage operated by NOS is located at the 
boundary of the present study area. Gage data were available for all 
27 storms in the northeaster ensemble. After subtracting the predicted tide,
