southeast, but higher speeds are associated with winds from the northeast. 

 Wind data from West Palm Beach are shown in Figure 9 (U.S. Congress, 

 1948b) . 



The area within a 50-mile radius of Fort Lauderdale experiences a 

 hurricane on the average of once in 6 years, with the probability of a 

 hurricane or tropical disturbance occurring once in a little over 3 years 

 (U.S. Army Engineer District, Jacksonville, 1971). The area within a 50- 

 mile radius of Jupiter experiences a hurricane on the average of once 

 every 9 years, and once every 2.6 years within a 150-mile (240 kilometers) 

 radius (U.S. Array Engineer District, Jacksonville, 1968). Ho, Schwerdt, 

 and Goodyear (1975) reported that from 1871 to 1973, an average of two 

 hurricane or tropical storm tracks crossed each 10 nautical miles (18.5 

 kilometers) of coastline in the region between Jupiter and Hollywood; 

 about 60 percent of these storms were hurricanes (Fig. 10) . In addition, 

 an average of 1.44 offshore storm tracks per year was reported passing 

 within 100 miles of the coastline in the vicinity of West Palm Beach 

 during the same time period. 



4. Oceanographic Data . 



Tides are semidiurnal, with mean and spring ranges of 2.5 and 3.3 

 feet (0.76 and 1.01 meters), respectively (National Oceanic and Atmos- 

 pheric Administration, 1973). The axis of the north- flowing Florida 

 Current passes quite close to the shoreline in the study area, with an
