depicitions than large or severe events analyzed in a routine manner. Based 

 upon pressure and wind data, the detailed analyses tend to show events as 

 more intense (at least over some fraction of the area involved) and of greater 

 duration. A procedure should be developed to minimize the bias toward 

 higher minimum pressures, shorter durations, and perhaps smaller size that can 

 result from unedited use of the operational analyses. The procedure should 

 consider the results of the studies summarized in this report section.
