Based on surface maps on the 0z GFS, the only difference is that the HP is slightly SW compared to 18z. the LP placement appears on 0z sunday on the 9th the exact same as the 18z.
On this run, the NC coast still gets obliterated with rain and surge, and since the Storm moves SW, it goes over hot gulf stream waters and re intensifies quickly. Take verbatim, it's an awful run.
Maybe premature. but GFS through 96 is what could be considered the worst scenario, a long stall just off the coast, then a small trek SW over new warm Gulf stream waters before making landfall.(If it does?)
12z GFS hour 6 has a pressure at 961 when it is already in the 940's. 12z Icon at the beginning of the run is in the 970's. seems that NO model is handling the rapid strengthening of the storm anywhere near accurately. Gonna shock me if it doesn't hit cat 5 by this evening.
The thing to pay attention to as others have mentioned is if the GLL interacts more on other models as opposed to the NAM, that's one of the biggest factors right now. Trend is our favor right now, but that can easily change.
