0z CMC...cut off low shoots NE ala NOGAPS...but like strings out 95L to just a huge area of low pressure....weird..

Maybe not so weird if you think about 95L/?? getting to the Yucatan and losing most of its' core just before/as the trough picks it up. The front is depicted to make it all the way to the Yucatan and I honestly am not sure it will, but if we go with that scenario it isn't quite as weird as it seems.

Damn.. the GFDL blows this up into a major hurricane 937mb 134kts.

It does remind you of her in the early stages, though.

We'll see. I think it is a bit early for a Caribbean buster.

This upper cutoff low is causing some serious model uncertainties, some of the models just shear this one totally out but slightly alter the timing and you've got a Wilma type system running into Florida.
Honestly this is going to be a tough call, this thread has a long way to run yet!
If it does stay offshore near the Yucatan I see no reason why this won't strengthen decently into a strong system...but this is a complex set-up and there could quite easily be some shear from the cutoff low yet, we'll have to see!

06z GFS doesn't really do much out to 96hrs, takes the system just to the north of Honduras and sits there for a while as well...
If it is a TC its probably a close call as to whether its far enough away from land to really strengthen much, but either way flooding rains would be an issue.

System moves near due east between 120-144hrs and strengthens, seems a slightly odd solution but both the ECM and GFS are suggesting that will be the case...we will see!

168hrs sees a strengthening system swinging back WNW, quite an interesting solution, down to 997mbs just south of Cuba:

06z GFS seems a little bit slower then the 00z GFS with the forward motion but seems to be quicker with exiting the cutoff low and takes the system on a path probably very similar to Irene once past Cuba...just a smidge further north and across S.Florida.
Would give a good chunk of the state some decent winds though thats for sure!
ps, then the system really races to the north into N.GA by 228hrs and starts to go extratropical inland by 240hrs.

Cheers for that ronjon, it seems like the ensembles are slower at lifting this system out though the actual position is very close to what the GFS has been expecting for 180-192hrs, so just a little slower in the end.

Run after run we are consistantly seeing a threat to a good portion of Florida by some of the more reliable models. I think it is fair to start assuming that we are going to see some impacts from this system. The question is how much, how strong?

Hurakan, good agreement now at least for the first 72hrs of a track just to the north of Honduras...
There is some models though trying to take this into the BoC so will be interesting to watch if more models try and do the same thing...also seems to be an awful lot of uncertainty with what happens once the steering currents go slack.
Real tough call!
