Intertropical Convergence Zone
A tropical wave moved off the coast of Africa near Dakar on August 31. It moved westward into the Intertropical Convergence Zone, and organized into a tropical disturbance on September 2 with a small, circular area of convection. The system moved to the west, and on September 3, the convection diminished after moving west of 40° W. By the next day, the tropical disturbance was barely discernible from the clouds of the Intertropical Convergence Zone. The wave gradually became detached from the ITCZ, and based on a reconnaissance flight that confirmed the existence of a low-level circulation, it is estimated the system developed into a tropical depression on September 5 while located 255 miles (415 km) east of Grenada.
