Tropical Depression Six formed from a tropical wave that moved off the coast of Africa on 14 July. Moving westward at about 20 kt, enough organized convection developed to classify the system as a tropical depression by 19 July, at a location about 900 n mi east of the Lesser Antilles. The depression moved westward for two days and was approaching the Lesser Antilles on 21 July when data from a U.S. Air Force Reserve reconnaissance aircraft indicated that the system had no closed low-level circulation. The open tropical wave continued westward across the Carribean for a few more days. The northern part of the wave split off toward the northwest and developed into Tropical Depression Seven a few days later, while located east of Jacksonville, Florida.
Forecasts issued on 19 and 20 July brought the depression to hurricane intensity in three days. Watches and warnings were issued for several islands in the eastern Caribbean Sea as listed in Table 2. Nevertheless, the depression weakened to an open wave, bringing only a few showers across the islands.
