Tropical Storm Alpha (2005)
At the time it was thought that Alpha was the twenty-second storm of the season, and so was the storm which broke the 1933 season's record for most storms in just one season. However post-season analysis revealed that there was also an earlier subtropical storm, which made Alpha the twenty-third storm of the season. Alpha was the first tropical storm to be assigned a Greek-alphabet name after the list of hurricane names were all used up. This was just one of many records set by the 2005 Atlantic hurricane season.
