How do scientist name hurricanes once all the letters in the alphabet are used in one season?

When all the letters in the alphabet are used for naming hurricanes in a single season, meteorologists use the Greek alphabet to assign names. This practice was adopted in 2005, allowing for additional names like Alpha, Beta, and Gamma to be used. However, the use of Greek letters has been discontinued in favor of a new naming convention, which involves the creation of supplemental lists for future seasons. These supplemental lists will include additional names that can be used if the standard list is exhausted.
