Forecast for DELTA verified, as it made landfall within the high risk zone and was within the 100-115mph forecast range of intensity. Peak intensity and landfall intensity were very well forecast dating back to Monday, a full five days prior to landfall. Timing was off by five hours.

it's had that for like 7 cycles now...

Buuuuut, it's that pesky 300+ hour thing that's the problem - lol ...

It does this every year... and every year, I ignore it.  The GGEM likes to do this too... But, then... Sandy happened.

Oops. 

It does have somewhat of a Sandy look to it though.   I mean ...from distant orbit, that is.  Obviously no declaration of redux or analog in saying so, but.. having a matured TC cross Cuba and entangle with the westerlies... culminating in a snow bomb over eastern Ontario like that, really in concept is not different than Sandy. It did the same exact thing - but farther S. along the MA, and I think snow was accumulating in WV when the core of the f'er was still blazin' away at 24C clear to 500 mb level.

Leaves the question out there:  could a Cat 2 "hook" left into NY Bite with a 30' storm surge due to geomorphic funneling ?   Oh... you just asked about the GFS though

It’s 2020...so anything is possible this year. Cat 2 hooking left into NYC ain’t nothing for 2020 lol.

Cmc has it but weak.. just east of Florida  at hr240

it appears to be keying on general pan-wide systemic/numerical instabilities that exists through those lower latitudes of the SW Atlantic Basin - I was discussing similarly ..it's seems to be a recurrent Autumnal right of passage.   But in those specifics, the timing is way off between it and the GFS, the latter which doesn't even have its entity focused until 300+ hours; contrasting, the CMC is days ahead with an inverted trough over the whole breadth of the expanse and some paltry commitment to a TC ...

The take-away is a period of development potential over all of the western Caribbean, Gulf and adjacent to Florida as the primary concern for now.
