Just had a look at the Euro ensembles. Still a surprising spread for only 60 hour forecast. Many tracks south like the op run. There is quite a difference now between GFS and Euro at hour 60. Euro has had a left bias this storm though I believe.

18Z FV3 says not so fast GFS--not much different from 12Z. Edit: literally does not move from 66-72.

Yes, maybe 50 mile difference. Remarkable agreement for a 3-4 day forecast. I've decided to evacuate after holding out this long.

I believe they are referring to the possibility of the southern portion of the ridge that blocks Flo's western/SW progression to be eroded, allowing a path into SC/GA a la what the Euro shows.
