Eta is the 28th named Atlantic storm this season, tying the 2005 record for named storms. However, this is the first time the Greek letter Eta is being used as a storm name because in 2005, after the season ended meteorologists went back and determined there was a storm that should have gotten a name, but didn’t.
Hurricane season still has a month to go, ending Nov. 30. And in 2005, Zeta formed in the end of December.
