This study is an evaluation of Sasebo Harbor as a typhoon haven. Characteristics of the harbor discussed include moorings, facilities available, wind and wave action, storm surge and the topographical effects on winds prior to and during the passage of tropical cyclones. Problems to be considered when remaining in port and possible evasion procedures are examined. The tracks of tropical cyclones from 1947-1973 for the western North Pacific were analyzed to determine the probability of threat to the harbor. Observations by the author and information obtained in conversations with harbor authorities are utilized in reaching conclusions. The conclusion reached by this study is in full agreement with the previous study by Fleet Weather Facility, Yokosuka 1967, which considered Sasebo Harbor to be a safe typhoon haven for all but the largest of naval ships CVA, CVS. For these units evasion must commence early since the waters near Sasebo are restricted. To aid commanding officers, an operationally oriented flow diagram is presented which summarizes the locations of the various sections of the text that could be used in decision making. Author
