That’s by far the worst spot too given the OHC and reduction in shear. There’s too much shear for the lemon areas in the Gulf right now, but the tropical Atlantic wave is likely to develop given how convectively active it continues to be and the CAG could very well produce 1-2 TCs (more likely 1 imo). 
 

 Today the Euro ens/weeklies don’t have as much activity in the W Caribbean for midmonth as they had two days ago when I posted how much more active than climo it was.

0Z 10/4 EPS run for 0Z 10/15: note how busy it was in W Car

Yeah I think we’ll kind of see the signal ebb and flow the next few days. It’s still pretty far out.

It's crazy if this actually occurs.  It's a cold front that has not happened yet, interacts with a boundary and then turns into a strong coastal low.  We have had this before like a month ago. 

Not really "crazy." I'm an old man and I've seen a few Mid-Atlantic whoppers in October. In fact, from memory October is a much better month for nor'easters than November. Like March, October is a "change of seasons" month.

SUBTROPICAL low for the e coast this week-early next week?

Will this get some sort of NWS identity in the very near future if modeling continues on course (GFS/EC). ?

This is where NWS-NHC step in.  I accept their definition.  It is tropical moisture late this week unleashed by a developing cold core aloft (7h-5h as example this weekend) and the cold air bordering the system to the west and north. .

I've been out of NWS since 2018 but this might get an identity of some sort.  Little question in my mind regarding potential high impact along the coasts for LI-NJ southward and maybe across to the SNE coast?  I just want ECAI which has been consistent cyclically for an event since the 06z/4 cycle (see trop tidbits for `12z Monday Oct 13)

I hope this isn't a dumb question, but is there a website similar to Tropical Tidbits or Pivotal Weather where I can see graphical representations of Google AI model products?

I don't know if this is exactly what you're looking for but I like this site for deepmind tracks, at least.

Clock is ticking on Hurricane Season 2025 as far as U.S. threats.  Biggest show in town will be the coastal low Sunday into early next week for the mid and north Atlantic coast.  Lots of cool and dry air will be flowing into the central and eastern U.S. mid to late October.  That will sort of put the lid on anything major approaching the Gulf coast.  CAG looks to be under performing so far this season.  Still time for something to lift north but I think the window is shut as far as anything major for U.S.  Not to say the coming coastal storm will be insignificant.  Lots of coastal damage looks to be incoming.

How is 96L not named???

It looks really well organized but it is apparently over like only 21C waters. So, is it still nontropical? If it has become subtropical, it needs to be named imho.

 It’s almost certainly going to get named (whether subtropical or tropical) imho based on this special TWO and Papin being in the house! 8PM TWO will likely rise substantially from this:

Special Tropical Weather Outlook
NWS National Hurricane Center Miami FL
635 PM EDT Thu Oct 9 2025

For the North Atlantic...Caribbean Sea and the Gulf of America:

Special outlook issued to update information about the gale-force 
low located several hundred miles northwest of the Azores.

Active Systems:
The National Hurricane Center is issuing advisories on Tropical 
Storm Jerry, located just southeast of the northern Leeward Islands.

1. North Atlantic (AL96):
Updated: Showers and thunderstorms have become better organized 
today in association with a gale-force area of low pressure located 
several hundred miles to the northwest of the Azores. If these 
development trends continue, a subtropical or tropical storm could 
form as soon as tonight while the system moves slowly northwestward. 
Over the weekend, the system is expected to move over even cooler 
waters, ending its chances of further development. For more 
information on this system, including gale warnings, see High Seas 
Forecasts issued by the National Weather Service and Meteo France.
* Formation chance through 48 hours...medium...40 percent.
* Formation chance through 7 days...medium...40 percent.

 Folks,
 As weird as this season has been, it may get weirder!
A look just now at historical genesis locations on record tells me that Invest 96L, already way up near 44.5N, could easily become the furthest N genesis for either a TC or STC as the furthest N on record is 42N (unnamed storm in 1952)! And it figures this would be named Karen, which would almost certainly mean that she’d be back in 2031, part of the Karen plan to bother us again :lol::

 Edit: here we go! Like her or not, Karen, who complained to forecaster Papin about not being heard, looks to be coming, folks, with her chances up to 60%/60%!

Tropical Weather Outlook
NWS National Hurricane Center Miami FL
800 PM EDT Thu Oct 9 2025

For the North Atlantic...Caribbean Sea and the Gulf of America:

Active Systems:

Storm Jerry, located just southeast of the northern Leeward Islands.

1. North Atlantic (AL96):
Showers and thunderstorms continue to show signs of organization 
with a small gale-force area of low pressure located several hundred 
miles to the northwest of the Azores. Only a small increase in 
organization could result in the formation of a subtropical 
or tropical storm as soon as tonight, as the system moves slowly 
northwestward. Over the weekend, the system is expected to move 
over cooler waters, ending its chances of further development. For

She’s demanding her own thread, now!
