On September 23, a tropical wave moved off the coast of Africa into the far eastern tropical Atlantic. A trough north of the system gave it an early opportunity to gain latitude and it turned north-northwest. The system developed quickly and was named Tropical Storm Gonzalo the very next day. Gonzalo wasn't particularly well organized; the thunderstorm activity was stretched over the eastern side of a center of circulation that was elongated north-south. Over the next day, it passed just east of the Cabo Verde Islands, but the islands were spared the worst of the storm due to its asymmetry.
As it moved away from the islands, Gonzalo was beset by higher shear. The center lost definition steadily and the maximum winds decreased as convection was displaced even farther to the northeast. By the evening of September 26, the storm had transitioned into a post-tropical cyclone. The remnants slowed down and turned back toward the west before dissipating.
Gonzalo was a poorly organized and short-lived tropical storm.
Tropical Storm Gonzalo brushed Cabo Verde to the east, causing windy conditions that led to power outages on the islands. The storm's eastern side also brought significant rains to coastal Senegal, The Gambia, and Guinea-Bissau in west Africa.
