Through June 14th:
***** ALWAYS CHECK & RE-CHECK THE LATEST FORECAST & UPDATES! *****
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.
*** LOCAL (Jacksonville/NE Fl./SE Ga.) IMPACTS FROM THE TROPICS: None through the weekend & into next week
The Atlantic Basin Overview:
It’s the beginning of the 2024 Atlantic hurricane season. The good news - for now - is there are no areas of concern.
The season is forecast to be active largely predicated on unusually warm ocean temps. & a likely-to-develop La Nina (cooling of the equatorial Pacific which often correlates with less shear across the Atlantic Basin):
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:
Water vapor loop (dark blue/yellow is dry mid & upper level air):
June tropical cyclone origins (early season breeding grounds are the Gulf &/or Western Caribbean:
Averages below based on climatology for the Atlantic Basin for November (7 hurricanes so far, 19 tropical storms):
Wind shear (red - strong shear; green - low shear):
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. 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..... “Alberto” is the first 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 *.
