Tropics threats for Jacksonville/NE Florida/SE Georgia: None.
The Atlantic Basin Overview:
Multiple tropical waves extend from the Caribbean & the coast of Africa & may have some long term potential to slowly develop while moving westward across the Atlantic Basin. Right now most forecast models show little significant development through the end of August as there is a good deal of dry mid & upper level air, but it’s something to watch - especially the first couple of weeks of September. Keep in mind that the vast majority - more than three-quarters - of all tropical waves coming off of Africa do * not * develop into a tropical cyclone. And keep in mind that warm water alone is not the only necessary ingredient for tropical cyclones.
A piece of a 500mb (upper level) trough that is peeling to the west over the Northern & Northwest Gulf of Mexico & is producing some generally weak & disorganized convection while approaching Texas. No surface development is expected.
In a general sense - longer range global forecast models show a fairly strong tropical wave approaching the Eastern/Northeast Caribbean in about 10 days. This wave is something to watch the first week or so of Sept.

REMEMBER WHEN A TROPICAL STORM OR HURRICANE IS APPROACHING: Taping windows is *not* recommended & will not keep glass from breaking. Instead close curtains & blinds.
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 where damage might occur.

The upper oceanic heat content (UOHC) [tropical cyclone heat potential/TCHP] across the SW Atlantic, Gulf & Caribbean is unseasonably high for this time of year:

Saharan dust spreads west each year from Africa driven 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* interfere with 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 dust plume then try to develop if other conditions are favorable (we’ve already seen this with Beryl & Debby this year). In my personal opinion, there is way too much “hoopla” about the presence of Saharan dust & how it relates to tropical cyclones. In any case, the peak of Saharan dust typically is in June & July.

2024 names..... “Francine” is the next 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 (the last time this year’s list was used)... Dorian in ’19 & Laura, Eta & Iota in ‘20, Ida in ‘21 & Fiona & Ian in ‘22]). In fact, this year’s list of names is rather infamous because of the ‘04 season when Charley, Frances, Jeanne & Ivan - all retired names - hit Florida within a matter of about 6 weeks. The WMO decided - beginning in 2021 - 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 *.

A Tropical Storm WARNING: Hawaii County
“Hone” became a hurricane Sat. night with its closest approach to the Big Island of Hawaii through the day Sunday producing some squalls but - in the end - not a major hit on the islands:

“Gilma” will gradually weaken while slowly gaining latitude as the tropical cyclone turns more northwest likely keeping what’s left of the system a fair distance northeast of Hawaii late in the upcoming week:
