On September 10, an area of clustered thunderstorms began to move off the western African coast. It quickly became stronger and organized itself to become Tropical Depression Eight. Continuing to organize, it reached tropical storm strength on September 13, becoming a hurricane on September 16 and a major hurricane (Category 3 or higher on the Saffir-Simpson hurricane scale) on September 17. Helene moved generally west-northwestward before commencing a northeasterly turn. Large currents from Helene lashed Bermuda. The hurricane then became an extratropical storm on September 24 and died shortly after.
