Final answer:
There are six hurricane name lists rotated for Atlantic storms, reused every six years, with certain names retired after significant storms.
Step-by-step explanation:
The number of hurricane name lists that are rotated for Atlantic storms is six. The World Meteorological Organization maintains these lists, which are used sequentially and recycled every six years. That means the list of names for 2020 will be reused in 2026, except for those names that have been retired due to being associated with particularly costly or deadly storms. Retired names are replaced with new ones. The naming of storms serves a vital purpose in helping the public quickly identify storms in warnings and news reports, and it also aids in the historic tracking of each storm's impact.
