JACKSONVILLE, Fla. Weve only got four names left unused (Sally, teddy, Vicky, & Wilfred) on the 2020 Hurricane names list and we are approaching the peak of the Atlantic Hurricane Season. Once we exhaust those names we move on to the Greek Alphabet for storm names like Alpha, Beta, Delta, Gamma, Epsilon, etc. While there are 26 letters in our traditional alphabet, there are only 22 storm names on the annual hurricane lists, skipping letters like Q, U, X, and Z. There are six rotation lists of names that the WMO uses for hurricane names. The 2005 hurricane season has the most retired names five for one season.
