On September 9, a tropical wave moved off the coast of Africa. Despite moving through a dry environment, its convection became organized as an anticyclone developed over the wave. On September 14, convection was well-organized enough around a small closed wind circulation to classify the system as Tropical Depression Ten near Trinidad and Tobago. Land interaction from Venezuela later weakened the depression back to a tropical wave. The wave continued west-northwestward through the Caribbean, and redeveloped into a tropical depression on September 17 while south of Jamaica.
