2021 Hurricane Names
Hurricane names for the north Atlantic and northeastern Pacific Oceans
Hurricanes, tropical storms, and tropical cyclones in other parts of the world are identified by names. The north Atlantic and eastern north Pacific oceans both use a six year rotating list of hurricane names.
If a hurricane is severe, that hurricane name is retired and a new one is chosen to replace it. Retiring a hurricane name is subjective. The loss of life and the amount of damage are the two primary considerations for retiring a hurricane name. A tropical cyclone still can be very powerful, but if it is at sea and causes little or no problems, that name will not be retired. If any hurricane name is retired from the 2021 eastern Pacific or Atlantic hurricane season, the list of hurricane names for 2027 will be adjusted by the National Hurricane Center.
In the central north Pacific, four lists of hurricane names are used. Hurricane names are used in sequence from year to year, picking up where it was stopped the previous hurricane season. Hurricanes that form in the eastern Pacific and cross into the central Pacific will keep their same name. Only tropical cyclones that form in the central Pacific will be given central Pacific names. In a similar fashion if a tropical cyclone forms in the Atlantic basin, it will keep that name if the circulation holds together and moves into the eastern Pacific Ocean. On rare cases the opposite has been true.
When a system moves from one ocean basin to another a new name is given if the circulation dissipates over land. In 1988 Hurricane Joan moved from the Caribbean into Central America and caused widespread distruction. It dissipated into remnants and reformed in the Pacific as Hurricane Miriam. Conversely, Hurricane Barbara during 2013 formed in the eastern Pacific and made landfall in southern Mexico. The circulation center dissipated over land, but the remnants reformed into Tropical Storm Andrea in the Gulf of Mexico.
A supplemental list of hurricane names will be used starting with the 2021 hurricane season. This list will be used if the complete hurricane name list is exhausted. It was decided by the World Meteorological Organization (WMO) that the greek alphabet would no longer be used if a seasonal list was finished. A number of reasons for the change was given with focus on the names and explaining their use as opposed to focusing on the impacts of the tropical cyclone.
