Saffir–Simpson hurricane wind scale
Four tropical cyclones developed in September, including tropical storms Greta, Hallie and Judith, as well as Hurricane Inez. Peaking as a strong Category 4 hurricane on the Saffir–Simpson hurricane wind scale with winds of 150 mph (240 km/h), Inez was the strongest tropical cyclone of the season. Although Inez persisted into October, no other system developed that month. Two named storms usually form in October. The final tropical cyclone, Hurricane Lois, existed from November 4 to November 11.
