A tropical wave over the Eastern Atlantic has some potential for short term development - in the middle of “nowhere” - through the weekend before the wave moves into a hostile environment full of shear & some dry mid & upper level air. Once the wave gets farther west - over the Western Caribbean &/or SW Gulf of Mexico by next weekend or so, conditions may again become more favorable for development.
Overall... the “wave train” off Africa is going strong & it’s likely just a matter of time before we see significant tropical development over the Atlantic.

Saharan dust.... Tropical waves continue to “fester” along the south edge of the dust & have the potential to thrive once away from the dust.
2020 names..... “Josephine” is next on the Atlantic list (names are picked at random by the World Meteorological Organization... repeat every 6 years... historic storms are retired (Florence & Michael last year) & Dorian is certain to be retired from the ’19 list....
