REMEMBER WHEN A TROPICAL STORM OR HURRICANE IS APPROACHING: Taping windows is *NOT* helpful & will not keep glass from breaking.
Realize the forecast cone (”cone of uncertainty”) is the average forecast error over a given time - out to 5 days - & *does not* indicate the width of the storm &/or damage that might occur.
* An active tropical wave - ‘94-L’ came off the coast of Africa Wed. & is chugging westbound. Conditions for organization in the short term are marginal all the way to the far SE Caribbean largely due to the proximity of dry mid & upper level air + moderate to strong shear. This wave has long term potential next week - especially once into the Central & particularly Western Caribbean - IF the wave can survive potential land interaction with S. America. This low latitude track makes the intensity forecast a little tricky, but it does appear the recent persistent upper level high will remain intact across the Atlantic & U.S. (Lower 48) which would result in a rather straight forward forecast track. The question then becomes one about shear & the possible land interaction relating to intensity. The GFS & European long range global forecast models continue in remarkable agreement with some possible interaction with S. America followed by “bowling ball” west into Central America late next week/weekend. Such a track would imply no impacts on NE Fl./SE Ga. ... or any of Florida... & probably not any of the Gulf Coast. Of course, still early on this one. It is worth noting early season African waves are often a harbinger of an overall active Atlantic hurricane season.
A pair of tropical waves are on either side of ‘94-L’. The leading wave will soon be over the Caribbean with some gusty/heavy squalls but otherwise little development... the second wave is over the far E. Atlantic which forecast models dissipate in the long run.
* A good deal of storminess (convection) continues tucked over the far SW Caribbean. Proximity to land will likely preclude much surface development.
* Low pressure is forecast to develop over the far NW Gulf of Mexico through next week. Proximity to land may limit development, but this is a weather feature to keep an eye on.
Wind shear analysis shows winds out of the west at more than 50 mph! over parts of the Southern Gulf & N. Caribbean:
The location of development of tropical systems in June since 1851 generally favors the NW Caribbean, Gulf of Mexico & far Western Atlantic:
Saharan dust is spread west each year from Africa by the prevailing winds (from east to west over the Atlantic). Dry air - yellow/orange/red/pink. Widespread dust is indicative of dry air that can impede the development of tropical cyclones. However, sometimes “wanna’ be” waves will just wait until they get to the other side of - or away from - the plume then try to develop if other conditions are favorable. In my personal opinion, way too much is made about the presence of Saharan dust & how it relates to tropical cyclones. In any case, we’ve already has a couple of dust plumes spread west to the Caribbean & Gulf with the peak of Saharan dust typically in June & July.
2022 names..... “Alex” was the first name on the Atlantic list (names are picked at random by the World Meteorological Organization... repeat every 6 years... “Bonnie” is next. Historic storms are retired [Florence & Michael in ’18... Dorian in ’19 & Laura, Eta & Iota in ‘20 & Ida in ‘21]). The WMO decided - beginning last year - that the Greek alphabet will be no longer used & instead there will be a supplemental list of names if the first list is exhausted (has only happened three times - 2005, 2020 & 2021). The naming of tropical cyclones began on a consistent basis in 1953. More on the history of naming tropical cyclones * here *.
