GFS has been showing development in the western Caribbean for three runs in a row, now in only 6-7 days. Will be the next place to watch. Hoping that nothing develops or that it is more of a gulf threat, since the west coast of Florida will be uniquely vulnerable

Leslie has been feeling shy, so of course once model intensities have plummeted and all eyes are off her she has decided to put on a show

00z GFS sends an even stronger major hurricane into the same area in 12 days, and sends it up the eastern seaboard. Almost certainly not verifying but would be absolutely catastrophic if it did.

This is quite a rare case of EPAC-ATL crossover, but in the opposite direction! Typically Atlantic systems cross over to the EPAC, but this late season the crossover AOI from the EPAC to the Gulf of Mexico has worked in tandem with CAG-induced instability and vorticity in the region and produced a bonafide low pressure region with intense and persistent confection. I’d still doubt major hurricane status given the northerly shear, but the setup is quite conductive for west to east GOM systems - a rarity even in the past 100 years. Will be interesting to see the evolution of this system, and how it interacts with the punishing high pressure, the trough to the North, and potentially even Leslie if it scoots across the peninsula fast enough.

Crazy season to track. From a cat 5 early July major, to a total shutdown of the basin in peak season, to multiple powerful major hurricanes causing the greatest damage since Katrina during late season. 2024 will be talked about for many decades in the future, not just due to the incredible amount of hurricane landfalls on the gulf coast, but due to the truly anomalous pattern of tropical cyclonegenesis and intensification. Is this another artifact of AGW or just a season with many conflicting signals which have constructively and destructively interfered with each other, or both? Only time will tell.

Keeping my eye on the wave behind soon-to-be Kirk. It would be unprecedented to have a storm form in the East MDR and make it to the islands in October, but the ICON and EC-AI have been showing that as a possible scenario. The future storm is kept locked under a potent ridge that builds just slightly ahead of the disturbance as Kirk moves North. Hard not to buy the early recurve solution but this has been a season of odd behavior.

The story of this hurricane is going to be the horrifying inland flooding. Entire towns in TN and NC wiped off the map, houses destroyed and the landscape reshaped. Probably dozens of people if not more dead that are unaccounted for. The most impactful hurricane since Ian.

The MLC has been starting to rotate pretty quickly in the past few frames. Now that the low and mid level centers are more or less aligned, think we are finally seeing the start of eyeball building, though there is a long way to go

Really impressive convection, shear is quite low over the blob as there is a potent anticyclone. The lower level circulation is likely still right off the NI/HD border but it could drift right, especially if it cannot fire off its own convection and alignment occurs to the East.

It’s tough in a way since I recognize in “said poster” a little bit of what I saw in myself when I first started tracking weather; boundless enthusiasm, heat-of-the-moment that nowadays I look on as barely better than spam, and inexperience. Unfortunately the inability to read the room and understand that clogging up thread after thread with the same sort of post is a disruption that brings down the quality of discussion and information isn’t acceptable, especially during peak season. Early in the first years I was into weather, there was a poster on a forum I frequented with the username Tasmanian (Taz). His posts were somewhat similar in manner but far less spammy and engaged critical conversation and insight. He was a legend of the forum, and it’s not too late for “said poster” to learn a lesson. Anyhow, going to be an active few days, and if the 18z GFS is correct potentially an active few weeks. 97L appears to be setting up as a Michael redux (potentially weaker and larger), but these systems are always full of surprises.

Still watching this one. Steering pattern looks to be such that if this ends up east of the forecasts it could be shunted up the Atlantic, potentially close or on NE, like that GFS run a few days ago. Quite unlikely but it’s something, and we’ve had storms arrive in that manner from the West before

18z GFS is all over the place, but one thing it does have is signal. This may be the largest percentage of developing members we’ve seen for the AOI yet. We might not get much from this system but it sure isn’t being dropped

Ironic that right as everyone is becoming bearish there’s finally something to actually look at. This seems a step beyond what many models had in terms of convective activity for today

Benchmark for serious interest on my end is any sort of impact within 168 hours (7 days) on the models. We’ve had ~3 semi persistent modelcanes this season, and the signal vanished at that time or before for each one. If NE is getting even getting scattered hits after that then we could be on to something.
