Also, this season was more active, costly, and deadly than the previous season.
2006 Atlantic hurricane season
Tropical Storm Zeta formed on December 30, 2005, and lasted until January 6, 2006. Although the majority of its existence was spent in 2006, it is officially a storm of the 2005 Atlantic hurricane season because that is the year in which it formed. Zeta joined Hurricane Alice as only the second North Atlantic tropical cyclone in recorded history to span two calendar years.
