2026 Atlantic Hurricane Season

[Windspeed]

That’s pretty far south and impressive so being there instead of east of IC  MD , does that permit opportunity for a more easterly component to movement ?

We're several days away. The important thing to note from satellite is that there is a surface trough with regions of spin. Some of that energy may even split off to the east. But a surface low will eventually organize, intensify and move near the Mid-Atlantic or New England. It's a bit chaotic between operational runs right now because we're dealing with a phasing situation in 48-72 hrs.

Also, you know how tell the season is dead? When the entire discussion has been taken over by a potential mid-latitudinal coastal storm in the main tropical thread.

So this should be to the OC/DC latitude around 12-6pm Friday?

Joe Bastardi makes a good point about this likely being warm core at least in the early stages since it would be forming over 82-83F water. He said it weakens as it moves toward the coast because that’s what a warm core storm would do as it gets into cooler SSTs.

The new 00Z EC-AIFS has become more aggressive with the cyclone.

At F78, 06Z Saturday Sep. 26, it's down to about 989 mb. Compare that with the 18Z AIFS at roughly the same point, which was around 997 to 988 mb depending on the exact six-hour frame. More importantly, look at the position: the 00Z AIFS still has the center much farther west than the 00Z GFS, sitting roughly east of the Delmarva/NJ corridor rather than racing harmlessly toward the open Atlantic.

And look at the structure. The isobars are extremely tightly packed on the western and northwestern side, right toward the Mid-Atlantic and southern New England. That's a very substantial pressure gradient between the cyclone and the 1026 mb high to the north.

The deepening sequence on this 00Z AIFS is also worth watching. We had approximately 999 mb at F54, and now 989 mb at F78. That's 10 mb in 24 hours, so this particular 24-hour interval is not bombogenesis. But the cyclone is already quite deep by Saturday morning, and what happens during the next 12 to 24 hours is the fascinating part.

FWIW, the GFS operational has brought back a CAG system in the midrange, lifting it into the GOM the past few runs. The 00z was more pronounced with a hurricane.

GFS suite for the past couple of days may be locking onto the New England 5H trof too much... EPS modeling insists northward moving - deepening sfc low up against a strong surface high Quebec area. 

The phase diagrams for the EC glom onto a weakness off the Carolinas tomorrow and make its briefly warm core before asymmetric warm core and eventually degrading cold core system.  This has been ongoing modeling for several days.

So it seems to me WPC took a compromise of yesterday's modeling.  Nothing yet from NHC that I can find regarding a possible subtropical storm evolution so they are seeing guidance that mutes or nullify that possibility-rely on their guidance. 

This will probably be my last for this on the forum. It's several days of EPS vs GEFS through the 06z/23 cycle (inclusive of AI EPS).  Believe what you wish-

me, Im preparing my ball club for a rainout Fri night-Sun night in nw NJ and believe a decent G wind 45 MPH-rain drenched leaves taking out power all the way back to the NJ coast this weekend-esp Sat. NWS offices are onto the coastal flooding. 

I dont like to be embarrassed by wrong planning (relying too heavy ily on the EPS indie of 5 days) so I recommend you continue with official NWS products as your primary guide.

Appears as if Fay has come back from the dead

I need hurricanes at this point. Just one or two, but preferably three.

 There are two AOI in the Atlantic being monitored by the NHC, Invest 90L just off Africa and a possible regenerating Fay:
 

Tropical Weather Outlook
NWS National Hurricane Center Miami FL
200 PM EDT Wed Sep 23 2026

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

1. Far Eastern Tropical Atlantic (AL90):
An area of low pressure located a couple of hundred miles southwest 
off the coast of western Africa is gradually becoming better 
defined, and the associated shower and thunderstorm activity has 
increased since yesterday. This system could become a short-lived 
tropical depression on Thursday or Friday while it moves 
northwestward to northward. However, strong upper-level winds 
should end the opportunity for development by the weekend. 
Interests in the Cabo Verde Islands should monitor the progress of 
this system as gusty winds, areas of heavy rain and flash flooding 
is possible there by Friday.
* Formation chance through 48 hours...medium...50 percent.
* Formation chance through 7 days...medium...50 percent.

2. Central Subtropical Atlantic (Former Tropical Storm Fay):
Showers and thunderstorms have increased with the remnants of 
Fay located several hundred miles southwest of the Azores. While 
environmental conditions are only marginally conducive for 
development, this system could become a tropical depression again 
today or tonight if the current thunderstorm activity persists. 
The system is forecast to move westward during the next couple of 
days, and by the weekend upper-level winds should inhibit formation 
chances.
* Formation chance through 48 hours...high...70 percent.
* Formation chance through 7 days...high...70 percent.

Edit: 12Z UKMET has Fay not only hanging around for at least 168 hrs but being its strongest at hour 168 as it slowly moves WSW!

Lamest Hurricane season ever.

I am ok with that given that last decade.

“Lame” is good for us SE folks, especially those of us with elderly loved ones. Many in the SE US, even well inland, have had a very rough 2016-24. I was heavily affected by 5 storms. I’ll always take the very rare quiet season over that, especially because it will likely not be quiet next year.

Nothing wrong at all with a reprieve. 16-24 was brutal for the continental U.S. and this year has been bad for Hawaii.
