 The CPHC also introduced a revised set of Hawaiian names for the Central Pacific, after they had worked with the University of Hawaii Hawaiian Studies Department to ensure the correct meaning and appropriate historical and cultural use of the names.The practice of retiring significant names was started during 1955 by the United States Weather Bureau in the Atlantic basin, after hurricanes Carol, Edna, and Hazel struck the Northeastern United States and caused a significant amount of damage in the previous year.Initially the names were only designed to be retired for ten years after which they might be reintroduced, however, it was decided at the 1969 Interdepartmental hurricane conference that any significant hurricane in the future would have its name permanently retired.
