Calculation of Probable Maximum Wave 



The time required for a length e^ual to the 

 radius of maximum winds to pass a point if 

 hurricane is moving \Nith a forward speed 

 equal to Yp.

Note: The above wove conditions ore for deepwoter 

 conditions, because of energy diisipatiqn 

 the wave heights will be lower at the island 

 site. The hurricane will be routed across, the 

 continental shelf usinq the bottom profile 

 given on next page^from Reference 5)
