Most likely landfall point is the FL panhandle west of Apalachicola. Possibly Panama City area. That's just a hair west of where the NHC track is now pointing. High pressure will be positioned over Texas next week, keeping Isaac away from us.

Through 111 hrs now - 26.6N/84.5W.
114hrs - 26.9N/85W
117hrs - 27.3N/85.3W (heading for Pensacola, it appears)
123hrs - 28.2N/85.9W (10am TUE - 150 miles south of Panama City)
132hrs - 29.4N/86W - heading north toward Panama City

I'm laying money down in the office it is a Morgan City to Mobile landfall.

My pick? Biloxi.

12Z GFS recap for those that can see the images:

The only thing I would add is that the GFS does slow Isaac down remarkably as it makes landfall.

Sort of like Georges (1998) but east.

wxman57 and srain... Any chance this could strengthen to a solid Cat 3 given its track?

Last thing I need to happen is for it to take out Destin.

Intesity forecasts at the range are a mere guess at best. The NHC has explained that this area of forecasting is what is being tested and as of August 31st, I believe that we'll see some unmanned drones sampling such things as eyewall replacement cycles and intensity. Also Embry-Riddle Aeronautical University is testing a very small drone to research intensity as well, I believe.

Also another thing we need to note, the size of this storm will mean intensification could take longer especially after exiting the islands.

Great reminders posted there. Looking at this made my head sping though. It seems like yesterday when Mayfield was the NHC director. What's even harder to believe is that Bill Read (and Proenza) has come and gone already too! Wowsers!

The 12Z Euro is tad further W than the 00Z run and stronger.

Posted: **Thu Aug 23, 2012 1:26 pm**

Yeah I noticed...a bit west (Euro)...very interesting days ahead.....

Posted: **Thu Aug 23, 2012 1:29 pm**

Ridge is flatter N of the Euro solution and suggests a WNW motion as well.

Posted: **Thu Aug 23, 2012 1:33 pm**

That 12z Euro run (ahem) ... um ... is a .... (ahem) ... a little disconcerting.

Posted: **Thu Aug 23, 2012 1:36 pm**

I do wonder what the PWC has to say.

Posted: **Thu Aug 23, 2012 1:40 pm**

Way W from the 00Z for the Euro. Nearing Lake Charles/Vermillion Bay as a potential Major Hurricane via the 12Z solution...
