Dear Tom, with all the hurricanes this season, we are now in the Greek alphabet. If we can get through that alphabet, what would we call tropical cyclones? Jim Dekker, Tinley ParkBarb B. Dear Barb and Jim, for now there is no “plan B” if the Greek alphabet is out of stock. However, those probabilities are infinitesimal. Hurricanes have been named since 1953 and the list of 21 names (Q, U, X, Y and Z are not used) has only been used twice: 2005 and this season. In 2005, six Greek letters were used, the last storm Zeta. The Greek alphabet has 24 letters, so there would have to be 45 named storms to reach Omega. A greater concern is the possibility of a major hurricane of Greek letters that would force a letter to be withdrawn. For this reason, there is talk of a second list of 21 storm names available for use in very active seasons.
