On September 11, a vigorous tropical wave moved off the west coast of Africa. The wave organized rapidly and spawned a tropical depression to the south-southeast of Cape Verde. On September 14, the depression intensified into Tropical Storm Helene while tracking west-northwest. Helene continued to intensify and was upgraded to a hurricane on September 16. The storm began to execute a northward track, and reached Category 3 hurricane status on the Saffir-Simpson hurricane scale on September 18, before reaching its peak intensity of 120 mph (195 km/h). It started to weaken when it reached the cold waters of the North Atlantic, and Helene dissipated on September 20, without having had major effects on land other than moderate wind gusts in the British Isles.
