Strong Nor'Easter/Hybrid Storm Late September 2026

[Rjay]

There's a good possibility of a impactful storm for the subforum this weekend.  If the storm comes close enough we can expect rain and strong winds.  The largest impacts will likely be significant coastal flooding over several high tide cycles and severe beach erosion.  This storm will also occur during astronomical high tides.  This has the potential to be a dangerous storm for the coast and an impactful storm elsewhere depending on exact track and strength. 

Enjoy tracking the event with us.

This one's going hurt me

It's every bit of this here at the beach.

Strong east winds for days ahead of this storm will pile water up against the shore.  A euro track would be no bueno for the coast.

Bye bye sand that's been mostly spared the past few winters for some areas!

18z euro is such a slow storm jeez

This should be "Fun" for Staten Island.

At a minimum this upcoming storm was always going to be about a coastal flood threat and strong onshore flow with possible gales.  Trends continue to support this.  Coastal warnings and advisories are already posted and will likely be extended past the current expiration times.  Strong onshore flow for several days / numerous high tide cycles along with a full moon.  Still looks to me like the Jersey shore and L.I. Sound get the worst of the coastal flooding / erosion as far as this sub forum are concerned.   Eventual surface evolution will determine if this goes past minor / to moderate coastal flooding.   Surface evolution will also determine how far inland rain and gusty winds get if they make it inland at all.  Complex evolution yet to be determined.  If EURO persists with 00Z cycle tonight and is doing something similar at 12Z tomorrow then threat for more effects further inland would increase.  Too soon to tell.  Something interesting to watch this over the next few days.

Let's see what the gfs says now....

And just when you thought gfs was coming west like last run it goes back east 

[TriPol]

The 00Z GFS has shifted the developing low a bit farther east than the 18Z run, at least in these early frames.

On the 18Z GFS, by early Friday the center was tucked closer to roughly the 70°W corridor. On the new 00Z run, the F48 center is still farther offshore, around the upper-60s west longitude, so call it roughly 100 to 150 miles east of where the prior run was trying to organize the cyclone at a comparable stage.

That is not a huge jump, but it is definitely not another westward correction yet.

The important part is that the blocking high is still very strong, so an initially farther-east low does not necessarily mean the later retrograde will also be farther east. With this setup, the bigger question is still where the storm gets captured and starts bending back.

So, early read:

18Z: farther west early.
00Z: modest eastward shift early.
Block: still very much there.

The F60-F84 frames will tell us whether that eastward difference survives or whether the 00Z run bends it back toward the 18Z/Euro idea.

Is there any way to increase the maximum file size of an upload? 52.47 kB isn't really a lot.

Overnight runs trended weaker and further east. Lets see what today brings.

Not sure. Euro looks like it was too amplified.

Let's wait and see what the 12Z data shows
