that Alpha was the 22nd storm of the season, and so was the storm which broke the record for most storms in a single Atlantic hurricane season set in 1933. However post-season analysis revealed that there was also a previously unnoticed subtropical storm on October 4, which made Alpha the 23rd storm of the season. Alpha's record-setting formation date as the season's 23rd tropical or subtropical storm would stand until 2020. It was broken by Tropical Storm Beta, which formed on September 18.
