PackGrad05 Posted 8 hours ago Share Posted 8 hours ago After looking at all the data and the runs, even though they are inconsistent, I still feel the most likely outcome is a slow approach to the SE coast and either making it inland or staying just off-shore, but then slowing down/stallings and dumping a lot of rain... The big story is going to be the rain/flooding. 7 Link to comment Share on other sites More sharing options...
Eskimo Joe Posted 7 hours ago Share Posted 7 hours ago Man 06z GFS op tries to bury 94L across interior South Carolina. Looks like a potent 850 and 700 mb jet just pouring subtropical Atlantic moisture into the foot hills. 1 1 Link to comment Share on other sites More sharing options...

olafminesaw Posted 7 hours ago Share Posted 7 hours ago I was looking for an Analog yesterday and couldn't find any TS/hurricane that originated near the Bahamas and took a left hook into the Bahamas. Model consensus vs climo, should be a fun showdown. Link to comment Share on other sites More sharing options...
GaWx Posted 6 hours ago Share Posted 6 hours ago Hopefully Humberto overachieving increases the chance that 94L will be more influenced by it in a way that helps the SE US. 1 Link to comment Share on other sites More sharing options...

RU848789 Posted 4 hours ago Share Posted 4 hours ago Greg Postell on TWC was just saying he thought there was enough evidence of a low level closed circulation to name this Imelda and isn't sure why it hasn't been named yet. Personally, given the wildly varying model runs to this point, I wonder if the NHC simply wants a bit more time to issue actual track/intensity forecasts. He also mentioned the conflict between anomalously warm waters ahead of Imelda vs. some very dry air aloft forecast to be in its path, making intensity forecasts very difficult - and we already know the impacts of the closed SE low and Humberto with possible Fujiwhara effects are making the track forecast very difficult. The one thing that seems almost a given is that at least parts of SC/NC/VA, especially near the coast, will get a lot of rain - how far inland that very heavy rain gets and whether we're talking 4-8" of rain (which most can handle) or 10-20" of rain (big flooding) is an open question.

When looking at recon earlier I didn't think that we had anything closed, but perhaps that's a function of the possible LLC being so close to the coast that recon can't get there. Looking at some of the surface observations, I guess you can close this off. I suppose the northerly wind on the south Cuban coast implies some sort of LLC. I just think it's marginal at best for now. 1 Link to comment Share on other sites More sharing options...

WxWatcher007 Posted 4 hours ago Author Share Posted 4 hours ago You can see pretty easily why the establishment of an inner core matters here. On the 06z GFS run, the core is weaker and less structurally sound, and as a result it’s easier for dry air to get entrained. The result is a slowly intensifying storm (take note) on landfall. 12z has a symmetrical core, which not only makes it stronger but closes off the eye from dry air entrainment. The result is a substantially stronger hurricane that is likely intensifying more robustly on landfall. I can’t emphasize enough how important it’ll be to get a well defined LLC so that the models can figure this out. I think an east coast strike is highly likely at this point given the GFS/Euro and their ensembles overwhelmingly overlapping in the general upper level steering features. 9 Link to comment Share on other sites More sharing options...
wthrmn654 Posted 3 hours ago Share Posted 3 hours ago Something I don't think anyone has talked about/ mentioned but this L has been tracking against guidance, nearly due west since at least 18z yesterday... i mean just look at the actual track versus modeling at 18z with each x. Being 00,06,12z actual placement...... this will likely dictate storms overall intensity the closer to Florida it gets along with all the islands is gotta cross. With 12z runs showing this likely a TS possibly barely a Cat 1 maximum strength wise 2 Link to comment Share on other sites More sharing options...

WxWatcher007 Posted 3 hours ago Author Share Posted 3 hours ago PTC likely later today Tropical Weather Outlook NWS National Hurricane Center Miami FL 200 PM EDT Fri Sep 26 2025 For the North Atlantic...Caribbean Sea and the Gulf of America: Active Systems: The National Hurricane Center is issuing advisories on Hurricane Humberto, located over the subtropical central Atlantic, and has issued the last advisory on Post-Tropical cyclone Gabrielle over the northeastern Atlantic. Southwestern Atlantic (AL94): Satellite data and surface observations indicate that a low pressure system appears to be forming near eastern Cuba and the southeastern Bahamas. This system is producing a large area of disorganized showers and thunderstorms, and gusty winds. Gradual development of this system is expected, and it will likely become a tropical depression during the next day or so while it moves northwestward or northward across the central and northwestern Bahamas. Regardless of development, heavy rains and gusty winds are ongoing in the Dominican Republic, Haiti, the Turks and Caicos Islands, the southeastern Bahamas and eastern Cuba, and are likely to spread across the remainder of the Bahamas over the weekend. Interests in all of these areas should monitor the progress of the system. Tropical storm watches or warnings could be required for portions of the Bahamas and advisories on a potential tropical cyclone could be issued as early as later today. While there remains considerable uncertainty in the long-range track and intensity of the system, there is a significant risk of wind, rainfall, and storm surge impacts for a portion of the southeast U.S. coast early next week. Interests in this area should also monitor the progress of the system. * Formation chance through 48 hours...high...90 percent. * Formation chance through 7 days...high...90 percent. $$ Forecaster Cangialosi/Reinhart/Hagen Link to comment Share on other sites More sharing options...
