A tropical wave exited Africa on September 1, and after initial development became disorganized. It moved west-northwestward for a week, reorganizing enough by September 7 to be declared Tropical Depression Seven about 1155 mi (1855 km) east-southeast of Bermuda.[27] At the time, the depression had persistent convection around a small circulation, and it moved steadily westward due to a ridge to its north.[28] Shortly after forming, strong wind shear diminished the convection and left the center partially exposed.[29] By September 8, there was no remaining thunderstorm activity,[30] and the depression degenerated into a remnant low-pressure area.[31] The storm dissipated shortly after as strong wind shear continued to cause the storm to deteriorate while located 980 mi (1580 mi) southeast of Bermuda.
