11 PM EDST discussions have been the most boring for the last few days, telling us is time to go to bed for some of us, tomorrow is a long day 8-)


Biggest change is it's a bit slower than the 5pm, track pretty much the same otherwise. Although the thing that sticks out the most is the "Isais " typo.

Yeah his Discussion seemed sort of anti-CLIMATIC, if you know what I mean. From commentary here I expected fireworks and hula gals at 11PM.


That's Pasch in a nutshell. He's a little bit more animated in person.... okay, perhaps not so much lol. He know's his stuff though. Just goes to show ya though, cerebral doesn't necessarily translate to descriptive or communicative.

Cone of Concern seems to be a little conservative when we know that is usually an error of where the center can be. Can be misleading to the public.

Seems it’s getting its act together at the moment


There just seem to be lots of posts on here that have been suggesting otherwise, per it’s appearance. Perhaps looks are deceiving


I was looking at the recon data. Nothing shows any signs of weakening. I wouldn’t get too caught up in appearance. This has been an ugly storm all the way but resilient

Interesting that recon jogged westwards in terms of center location whilst the convection jumped a little northwards. I think it's probably had some higher shear put onto it.

Would explain a far weaker and open core again after looking relatively good but a few hours ago.

Looking fairly steady state overall, though you can still get some strengthening even with a less stellar core.

Eric, I would still like to know what is the deal with Izzy's evil twin to the east? I appears to have some fierce convection and seems to pulse up and down
in sync on IR with the twin to the west?

Looks like the pressure might be down to 984 mbar.

I am only a meteorology enthusiast who knows a decent amount about tropical cyclones. Look to the professional mets, the NHC, or your local weather office for the best information.

I'm seeing an overall net motion that appears more north leaning. There's just no way do I see this storm track south of Andros.

CDO looks very good now but very small in relation to the whole storm size (whole circulation envelope) and that circ envelope is still stretched north to south with the big area of convection located to the east, so the symmetry is still pretty sloppy. A circle spins much faster much more easily than an oval or ellipse.

This is going to take that Floyd route through NC, VA, and out over Salisbury. I'm not looking forward to this week. I'm in Norfolk and we just aren't ready for high tide and flooding.

11PM track basically the same, maybe ever so slightly closer to the coast

Just like Jon Snow..."I know nothing" except what I know, and most of what I know is gathered by the fine people of the NHC

I think the shift in the cone was happenstance. The 12/24/36/48/etc forecast points were probably just extrapolated from the previous advisory.

Actually looking at this again recon has a NW heading, the NNW illusion is shear
