Hurricane Irene


Baroclinic Zone

Recommended Posts

You have to think the Euro's bizarre option of not moving it NE and instead moving due north won't verify. I have a hard time seeing it not moving east of north once it gets up into Virginia..but who knows.

I'd think a Euro/GFS combo might be a better solution.

Euro ensembles similiar to the op???

Yeah but I think that NE trend late in the game will screw CT.

I think a track over Cape is def possible.

still playing with the speed too. 06z gfs has hurricane conditions developing on Long Island saturday night.

I still have a hard time buying a SNE hurricane with the storm moving NE at 20 mph from the Outer Banks. To me that seems like a Belle kind of scenario.

Cane of 1821...not far off at all

Except 1821 was hauling... this will be crawling.

Don't underestimate the importance of baroclinic enhancement of SNE hurricanes. With the slow movement and no powerful phase we will see this weaken a little more quickly than most big hurricanes we remember.

I still don't think it's going to move as slowly as the Euro has it. Not hauling..but not moving 10 mph either. I'd bet it gets in here by Sunday in whatever form it ends up taking

Looks like the 00z Euro came E a tad overnight. Interesting that the models have been pretty steadfast for the past couple days bringing Irene up into the area. GGEM have been the furthest E but looks to be wobbling back and forth.

Looking for Irene to become a CAT 3 sometime today.

In this forecast range, models look infinitely better for SNE than Earl or Bill, and frankly for any storm since probably Floyd/or Edouard. Ingestion of new data overnight led to an incredibly clearer forecast track.

I think the %'s have increased in the overnight. This is certainly not the text book setup being discussed but not out of the realm. Very intriguing to watch unfold. 8am intermediate advisory will be out shortly.

If the eye goes over the cape what are we looking at for those west of the cape? Primarily heavy heavy rain?raining.gif

I remember when Bob slammed the Cape. I'm originally from Southborough (25 miles west of Boston), and I recall strong gusty winds with heavy downpours and one very loud crack of lightning. It was like being in an extended severe t-storm, but I doubt there were any hurricane force wind gusts.

On 00z GFS, 12z Sun, Irene was due east of ORF. On the 06z run at the same time the storm is about 50 miles SE of Montauk. An even more drastic shift from 18z run, 12z Sun, which only had Irene making landfall down in Wilmington.

Models are definitely starting to speed this up, and I expect that will probably continue. Even in such an unusual situation, I'd be surprised if it truly crawled up the coast.

Yes, you're probably right and that probably increases the threat for a scrape to the east.

I actually think that is the most likely scenario... a landfall in E NC and then a brush by SNE.

The second most likely scenario is a landfall to the west and an inside runner.

Least likely is the thread the needle scenario.

Just got up and looked at everything. Very impressive hit if the models held ground but they have been trending east now for some time. I have learned over and over "the trend is your friend". I have seen nothing to stop the east trend yet so I would be very leary of that. If the trend starts to lock at 12Z then I would be more excited. We are still 5 days out.

I do have a question about predessor rain events with hurricanes. Are they more apt to form with a slow moving system?
