The study is an evaluation of Apra Harbor, Guam as a typhoon haven. Characteristics of the harbor discussed include facilities available, wind and wave action, storm surge and the topographical effects on winds prior to and during passage of tropical cyclones. Problems to be considered if remaining in port and possible evasion procedures for ships sailing from the port are examined. The tracks of tropical cyclones from 1947-1973 for the western North Pacific were analyzed to determine the probability of threat to Apra Harbor. Observations by the authors and information obtained in conversations with port and harbor authorities are utilized in reaching conclusions. In general, the results indicate that Apra Harbor is not a safe haven. Under threatening conditions, all fleet units capable of evasion at sea should sortie at the earliest possible moment.
