The Caribbean/Gulf of Mexico & SW Atlantic will probably remain an area to keep an eye on over the next couple of weeks (climatologically favored too).

In the meantime, a couple tropical waves have moved west off the coast of Africa. Shear is strong between the Caribbean & African coast so development seems unlikely....

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 now. “Epsilon” is next... the first time the Greek alphabet has been used since 2005 (total of 27 named storms using 6 Greek letter names in ’05)
