Jacksonville, Fl. — The 2024 hurricane season was forecast to be active & - unfortunately - that forecast was accurate. The table below shows the average Atlantic hurricane season vs. Dr. Phil Klotzbach’s preseason forecast ... NOAA’s preseason outlook... & the ‘24 reality:
The season began with powerful hurricane Beryl in late June but then went relatively quiet until mid September:
Only 3 names were left on the ‘24 list:
5 hurricanes hit the U.S. - Beryl (Cat. 1), Francine (Cat. 2), Debby (Cat. 1), Helene (Cat. 4) & Milton (Cat. 3). The most landfalling tropical cyclones in a single season is 12 in 2020. The most U.S. landfalling hurricanes in a season is 6 set in 2020, 1985 & 1886.

24th - Tropical storm Helene forms over the Northwest Caribbean
25th - Helene goes hurricane over the Southern Gulf of Mexico; tropical storm Isaac forms over the North Atlantic
26th - Cat. 4 hurricane Helene landfall at 11:10pm EDT 10 miles W/SW of Perry, Fl/Big Bend. Local tree damage & power outages in Jacksonville, North Central Fl. near/north of I-10 & much of Southeast Georgia. “The Hell that was Helene” in the “Buresh Blog” * here *.
Helene strengthened rather quickly & steadily:
Highest storm surge values were along Central Florida coast reach 6-7+ feet. Generally less than 3 feet for NE Florida & SE Georgia:

The Atlantic Basin Overview:
It’s the last week of the Atlantic hurricane season... there are no areas of immediate concern.
Some long range global models show weak low pressure trying to form over the Southern or Western Caribbean & there continues to be a good deal of disorganized convection over the Central Caribbean. Any low pressure that might form should stay away from the Lower 48 of the U.S. as upper level troughing holds firm over the Eastern half of the U.S.
‘Velocity potential anomalies’ below. shows “Rising” air (green lines) equates with an uptick in overall convection. With rising air, conditions are generally more favorable for tropical development. Where there are brown lines, the air is generally sinking & is often less conducive to tropical cyclones (though not impossible to have development).
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 very high:
Water vapor loop (dark blue/yellow is dry mid & upper level air):
November tropical cyclone origins:
Averages below based on climatology for the Atlantic Basin for November:
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 (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..... “Tony” 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 *.
