PTC 9 not much better organization, per GFS, early going...

Despite having a small upper anticyclone over 92L and a larger one over 91L, GFS refuses to show development of both.

Quite comical actually - thru 96hrs, GFS says 91L, 92L and future 93L is a whole bunch of nothing. Looks like the NHC forecasters may have to go old school the next few days and nowcast with their eyes.

This is the same model that did not develop Gert and then realized it was there about a day after it formed.

Every other model is on board so it's probably something wrong in the GFS programming

The Navgem also show very little development so the GFS is not alone in what it shows

12z GFS... TW approaching SFL @114 hrs... Maybe a tad slower and S of 06z... Track is towards SFL, but fortunately intensity is a nice TW moving through... 8-)

GFS has the Upper Level Low deep into the Gulf backing W to the TX Coast ahead of 91L (and 92L). Pattern reversal is on the table there as it has a strong high coming down off the SE Coast and creating a block situation for 92L. It doesn't show development through 120 hours, but that's an interesting setup regardless of the proximity to 91L.

250-850mb wind shear with low centers:

That's astonishing. I'll bet anyone a $100.00 site donation that there is more activity at 132 hours than the GFS is leading on. Anybody.

I'm not taking that bet...not after seeing the cyclogenesis performance of the models on Gert.
