As an FYI - the NHC notes that the ICON model is an intensity model and not a model for track forecasting. It's a consensus model of the following models: DSHP, LGEM, HWFI, HMNI.



Yeppers.. its still a 1 up from the nogaps and cmc lol


I don't think so. ICON is a global model developed in Germany and its their version of ECM and UKMET. From what I've read, it has a finer resolution than ECM and relies on different grid structure (icosahedral grid structure) basically triangular.

That is NOT the same ICON. The ICON listed on the NHC site is just intensity averages of other models; it has no spatial component to it. The ICON plotted on Tropical Tidbits is a global model produced by Germany's weather service, info here: https://www.dwd.de/EN/research/weatherf ... ption.html


Thank you...that is what I thought. :uarrow:

It's subtle, but you can see weak ridging extends back into GA on the 12z GFS operational run at 78 hours:

I'm curious. The pressure drops to 981 by 30 hours on the 12Z GFS. Then it stays there and even raises 1mb over the next 18 hours - then continues lower somewhat rapidly. Is that mid-level dry air? Shear? ERC? I think a few expected Dorian to deepen over night. But, the comments about PR disrupting the feeder along with a little dry air was enough to hold him down. What do you think it is at hour 30 - 48 that keeps a lid on it?

GFS about 30 miles due south from earlier run as it sits off the Florida coast. After 90hrs is the big question mark whether it stalls and sits, stalls and turns, or creeps inland moving west. Nobody knows.

Btw, I still think GFS is a little too far north. I think Miami to Jupiter still the ground zero point. GFS doesn't take the WSW dip like I think this is going to do.

Yep. Looks another what? 30-40 miles south? And a LONG way south from Jacksonville overnight...
