 A powerful tropical wave moved off the coast of Africa on August 27.As it moved west into the Atlantic, it became more organized and the system developed into Tropical Depression Fourteen about midway between Cape Verde and the Lesser Antilles on September 1.Shear from an upper-level low to the southwest slowed the development of the storm and caused uncertainties in the National Hurricane Center's forecasts, as some models indicated that the depression would dissipate and others that it would become a hurricane.
