GaWx Posted September 19 Share Posted September 19 0Z GEFS says that the 0Z GFS is a major W outlier as just about all members recurve in the E Gulf. This is about the most threatening GEFS to W FL from Big Bend S of any run yet. 0Z UKMET has no TC through 168. Link to comment Share on other sites More sharing options...

NorthHillsWx Posted September 19 Share Posted September 19 One word of caution when looking at the GFS and CAG storms is that it is notorious for over estimating development and speed of development. These generally start as broad systems that can take awhile to organize. Looking at various models, a myriad of environments are depicted for the northern gulf including trough interactions, westerly shear, dry air. Not every model paints the most favorable picture for whatever develops and those details are not possible to resolve at this time. Now- that being said these also can be some of our worst storms, hurricane Michael being a prime example. I’d definitely use caution watching these endless GFS runs depicting gulf-filling monsters knowing it’s bias- but certainly it shows the potential. Key is all models show a storm in that timeframe and that is an extremely strong signal that a storm will form. NHC already bumped it up to an orange. 5 2 Link to comment Share on other sites More sharing options...

I'm actually surprised the NHC hasn't marked it yet, models are showing TCG taking place in the eastern Atlantic at a very similar time as the caribbean. The caribbean storm could very well be the dreaded I storm if it takes its time to organize... 1 Link to comment Share on other sites More sharing options...

yoda Posted September 19 Share Posted September 19 12z CMC is into W LA. 12z GFS is only 500 miles NE of where it was at 06z at 225/228. Headed into W FL north of Tampa. Comes off E FL coast near JAX at 240. Stays far enough offshore, but SE coastline from FL to NC gets raked 1 Link to comment Share on other sites More sharing options...
StantonParkHoya Posted September 19 Share Posted September 19 Pretty wild path on GFS. I’m skeptical of such an anomalously digging trough in late September to cause a full recurve. A landfall Mobile-Big Bend then NE seems more plausible. Link to comment Share on other sites More sharing options...
WxWatcher007 Posted September 19 Share Posted September 19 While it’s worth watching a possible one off in the dead tropical Atlantic portion of the MDR and perhaps something weak in the central Atlantic for TC genesis, obviously the western Caribbean is the place to pay closest attention. The homebrew signal I’ve been talking about since late August has evolved over the last week. Originally, the signal was for genesis potential off the SE coast and in the Gulf due to stalled frontal boundaries from anomalously strong late summer troughs. That led to our three invests, one which hit NS as a non tropical cyclone, one which became a PTC but fell just short of a tropical designation, and one that helped seed what became Hurricane Francine. Now we’re looking at a CAG signal, which as I’ve said before is a more tropical genesis pathway than what we formerly had. These can spin up one (most likely) or two TCs. While the ceilings are usually low, this environment seems like it has higher end potential given the extent of OHC, instability, and low wind shear—one area of the cool neutral ENSO that did come to fruition from the hyperactive seasonal forecasts. Everything remains on the table, and I think anyone in the Gulf and to a lesser extent folks on the EC should be paying attention to this. 1 Link to comment Share on other sites More sharing options...

GaWx Posted September 19 Share Posted September 19 The SSN mean for Sept to date has been much lower than the 215 of Aug. That is especially the case the last 10 days, which have averaged only ~128. There’s no way to know but perhaps this is one of the reasons the tropical Atlantic is waking up and likely soon headed toward normal to above average activity. Perhaps Atlantic tropical instability is increasing and, if so, the solar downturn may be contributing to that: 2024 09 01 2024.668 182 14.5 27 35 2024 09 02 2024.671 195 20.7 26 33 2024 09 03 2024.673 180 21.2 20 23 2024 09 04 2024.676 174 26.1 21 26 2024 09 05 2024.679 181 13.1 15 20 2024 09 06 2024.682 189 13.3 19 24 2024 09 07 2024.684 168 17.8 24 29 2024 09 08 2024.687 171 18.7 20 26 2024 09 09 2024.690 156 19.1 23 26 2024 09 10 2024.693 149 12.8 24 30 2024 09 11 2024.695 153 15.4 29 34 2024 09 12 2024.698 144 11.6 24 28 2024 09 13 2024.701 118 13.1 26 31 2024 09 14 2024.704 117 10.6 24 31 2024 09 15 2024.706 100 14.1 22 27 2024 09 16 2024.709 142 16.2 22 27 2024 09 17 2024.712 141 13.4 28 36 2024 09 18 2024.714 109 9.9 24 28 2024 09 19 2024.717 109 11.1 25 31 Link to comment Share on other sites More sharing options...

A track like that is entirely possible with the high latitude blocking in Canada/Greenland and wave breaking underneath. Plenty of Euro ensembles are showing something similar.
