When a hurricane season runs out of names in a particularly active season, the letters of the Greek Alphabet are used. Since the Greek Alphabet is the backup to the list of names every season, there could be a problem if a Greek Alphabet storm is worthy for retirement. Do Greek Alphabet Storms get retired? In 2006, following the first time the Greek Alphabet was required to complete a hurricane season, the WMO decided that it “wasn’t practical” to retire a Greek letter if it met the criteria for retirement because the use of the Greek Alphabet doesn’t occur frequently enough. If a Greek Alphabet storm is worthy for retirement, however the Greek letter would be included with the list of retired names with the year of occurrence, but that letter in the Greek Alphabet would still be used in the future.
