2020 names..... “Wilfred” was the last name on the Atlantic list (names are picked at random by the World Meteorological Organization... repeat every 6 years... historic storms are retired (Florence & Michael in ’18 & Dorian is certain to be retired from the ’19 list). Interesting side note: the last six of the names on the ’20 list had never been used. So it’s on to the Greek alphabet. "Kappa” is next... the first time the Greek alphabet has been used since 2005 (total of 28 named storms using 6 Greek letter names in ’05 [there was one unnamed storm). Theta broke the record for the most Atlantic storms in a single season on record at 29.
