Short-lived Tropical Depression Nine developed from a
strong tropical wave that moved off the west coast of Africa on 14
August and moved westward across the tropical Atlantic for several
days. The shower activity gradually increased as the wave
approached the Lesser Antilles. Once in the eastern Caribbean Sea,
the cloud pattern became better organized and, based on a west wind
reported by a ship in the area, it is estimated that a tropical
depression formed at 1800 UTC 21 August. Initially, the upper-level
environment appeared to be favorable for strengthening. However,
strong upper level southwesterly winds became established over the
depression and weakening began. Data from an Air Force
reconnaissance plane at 1800 UTC 22 August indicated that the
depression had lost its closed circulation and it dissipated just
south of Hispaniola.
