 Atlantic City. Note that the time period plotted corresponds to the time 

 between the prestorra and poststorm surveys, and the x-axis tick marks 

 correspond to noon on the date given.

21. A major benefit of the complete coverage offered by the hindcast 

 data is that it permits examination of all the wave conditions which occurred 

 between the selected surveys. Therefore, it was possible to determine if 

 more than one storm had occurred. Similarly, it should be possible to 

 examine the sequence of prior storms for any period or year. Though not yet 

 considered, the relative intensity and prior storm history may be important 

 in understanding and predicting a storm's impact. 



22. In addition to presenting the maximum hindcasted wave height for 

 each storm and locality, an estimate was made both of the return period of 

 the maximum wave height and of the storm wave duration. The return period
