The system formed from a big tropical wave that moved off the coast of west Africa on September 6. Because of strong wind shear, it did not get stronger over the next three days. On September 9, it developed an area of low pressure in the central Atlantic, between the coast of Africa and the Lesser Antilles. Slowly, the wind shear began to go away. Dvorak classifications were started on the weather system on September 11. By the morning of September 12, it had developed into Tropical Depression Eight. This took place about east of the Lesser Antilles. The same tropical wave eventually created another area of weather activity that became Tropical Depression Ten, with the help of other weather systems.
