MIAMI (CBSMiami) — Subtropical storm Alpha has made landfall in Portugal after becoming the first storm system, since 2005, to be named using a letter from the Greek alphabet.

Get out the Greek alphabet for the rest of 2020: Storms Alpha and Beta have formed. Before them, Wilfred was the earliest "W" storm on record.

If the Greek alphabet has to be used in 2020, it would follow the same list as 2005, starting with Alpha. This is similar to how most names are reused every few years, unless the name is retired.

With Alpha, National Hurricane Center turns to Greek alphabet for storm names For only the second time in history, we've run out of letters for named storms so we've moved to the Greek alphabet.
