When is a name retired?
A hurricane doesn't necessarily need to be a Category 3, 4 or 5 to be retired. The name is retired if a storm leaves major damage or deaths to avoid future confusion among the public. Since 1959, there have been 89 names retired. The most names retired in a single season was for the very active 2005 season. There have been 19 seasons without a name retired, and 2014 was the most recent. Names starting with the letter "I" have been the most retired, 19 in total, and 11 of those have occurred since 2001. Wilma has been the name retired with the latest letter in the alphabet.
Every year the World Meteorological Organization meets for a week in the spring, which is usually when they announce any retired names from the previous hurricane season. The 2020 meeting was canceled due to the COVID-19 outbreak. Therefore, there won´t be any names retired from the 2019 season yet. The organization plans to meet again in spring 2021, and they will review the storms from 2019 before making a decision to retire names. This is when storms like “Dorian,” “Lorenzo” and “Imelda” will likely be retired.
