when does a tropical storm get a name
Tropical cyclone naming Tropical cyclones and subtropical cyclones are named by various warning centers to provide ease of communication between forecasters and the general public regarding forecasts, watches, and warnings. The names are intended to reduce confusion in the event of concurrent storms in the same basin. Generally once storms produce sustained wind speeds of more than 33 knots (61 km/h; 38 mph), names are assigned in order from predetermined lists depending on which basin they originate. However, standards vary from basin to basin: some tropical depressions are named in the Western Pacific, while tropical cyclones must have a significant amount of gale-force winds occurring around the centre before they are named in the Southern Hemisphere.
List of retired Atlantic hurricane names In 1955, it was decided to start retiring the names of significant tropical cyclones for 10 years after which they might be reintroduced, with the names Carol and Edna reintroduced ahead of the 1965 and 1968 hurricane seasons respectively.[1] At the 1969 Interdepartmental hurricane conference the naming lists were revised after it was decided that the names Carol, Edna and Hazel, would be permanently retired because of their importance to the research community.[1][6] It was also decided that any significant hurricane in the future would also be permanently retired.[1][6] Ahead of the 1971 Atlantic hurricane season, 10 lists of hurricane names were inaugurated, by the National Oceanic and Atmospheric Administration. In 1977 it was decided that the World Meteorological Organization's Hurricane Committee (WMO) would control the names used, who subsequently decided that six lists of names would be used in the Atlantic Ocean from 1979 onwards with male names included.[1] Since 1979 the same six lists have been used by the United States National Hurricane Center (NHC) to name systems, with names of significant tropical cyclones retired from the lists permanently and replaced with new names as required at the following year's hurricane committee meeting.[1]
