The resultant wind speed and direction values for Norfolk, Virginia, and Cape 

 Hatteras, North Carolina, obtained from the NOAA, NWS Local Climatological Data 

 Summaries, are included beside the FRP value, respectively, for comparison. As 

 expected, the values for these two locations are somewhat different than the 

 values at the FRF since they are based on data records that were taken hourly 

 7 days a week, rather than the one-time daily readings obtained at the FRF. 



5. Visual Observations . 



Monthly and annual summaries of visually obtained wave data, wind roses, 

 and annual longshore current graphs are presented based on the data for 1977-79 

 in Tables 14, 15, and 16; visual observations were obtained using LEO program 



Table 14. LEO data summary, 27 July to 30 December 1977.
