History of Hurricane Naming Conventions

Ana

The name of the first Atlantic storm of 2015. Hurricane names rotate in a six-year cycle with the 2015 list being a repeat of the 2009 names.

78

The number of Atlantic hurricane and tropical cyclone names officially retired by the World Meteorological Organization. Although hurricane names are recycled every six years, for reasons of sensitivity, hurricanes and tropical storms that were so deadly and costly that re-use of the name would be considered inappropriate are retired.

1950

The year the Weather Bureau officially began naming hurricanes.

2005

In one of the busiest Atlantic hurricane seasons on record, 28 named storms formed, forcing use of the alternate Greek alphabet scheme for the first time. When the National Hurricane Center's list of 21 approved names runs out for the year, hurricanes are named after Greek letters. Of the 28 named storms in 2005, 15 were hurricanes in which seven were major (Category 3 or higher). Four hurricanes reached Category 5 status (Emily, Katrina, Rita and Wilma).

2013

Despite preseason forecasts for an active hurricane season, that year had the fewest Atlantic hurricanes since 1982. While the year had a slightly above-average number of named storms (14), only 2 of these storms became hurricanes. For the first time since 1994, no hurricane reached major hurricane strength (Category 3 or higher). No hurricanes and only one tropical storm, Andrea, made landfall in the U.S., causing one fatality.

10 Years Ago

Aug. 29, 2015, marks the 10-year anniversary of one of the most devastating hurricanes on record - Hurricane Katrina. The Census Bureau will compile a list of statistics looking at the 10-year timeline of states and cities affected by Hurricanes Katrina, Rita (Sept. 24, 2015) and Wilma (Oct. 24, 2005). (Tentatively scheduled for release July.)
