The Atlantic Hurricane Season officially ends each year on November 30th, but in 2005, that didn’t stop a form following one month later in the Atlantic.
That storm was Tropical Storm Zeta, which was officially recognized by the Hurricane Center on December 30th, 2005.
Zeta would not affect any landmasses, but became the second-latest tropical storm in modern recorded history to form in the Atlantic Ocean. It’s also one of two storms in that modern history to exist over two calendar years, since it lasted into early January of 2006!
Zeta was part of a very active 2005 tropical season that ended with twenty-eight storms!
