Why Hurricane Names Come Back Every Six Years

Atlantic hurricanes use six rotating name lists, so names usually return every six years unless a destructive storm gets its name retired.

Hurricane names are not chosen from scratch every year. In the Atlantic, the World Meteorological Organization maintains six rotating lists, with each list reused six years later. The names move through the list in order, alternating between male and female names and using a mix of English, French, and Spanish names. Certain letters are skipped because suitable names are harder to find and the names need to be easy to recognize and communicate during emergencies. If a storm is especially deadly or destructive, its name can be retired so that it will not be assigned to another storm. A replacement name is then selected for the rotating list. That means a familiar name can normally return after six years, but a particularly notorious storm can permanently remove that name from circulation. The system exists mainly to make warnings easier to communicate and remember. The Atlantic lists have also evolved over time. The Greek alphabet was once used when an exceptionally active season exhausted the regular list, but that system was replaced by a supplemental naming list after the unusually busy 2020 season. In 2026, the regular Atlantic list includes names such as Arthur, Bertha, Cristobal, Dolly and Edouard. Recent retirements show how the system changes when a storm leaves an especially serious historical impact. After the destructive 2025 hurricane Melissa, the World Meteorological Organization retired the name and selected Molly as its replacement for a future cycle.
