Tropical Storm Zeta

Date: December 30, 2005 • Location: Rome, Italy

Tropical Storm Zeta (pictured) became a tropical depression, making it the record-breaking 28th tropical cyclone of the 2005 Atlantic hurricane season, the most active in recorded history until 2020.

Tropical Storm Zeta was a very late-developing tropical storm that formed in the central Atlantic Ocean during the 2005 Atlantic hurricane season, forming one month after the season's official end. Becoming a tropical depression on December 30, and intensifying the following day into the season's 28th storm, Zeta continued into January 2006. It was one of only two Atlantic tropical cyclones to span two calendar years.
