Even with the GFS coming south to start the run, if I take it's position at hour 78: there have been 20 storms since 1980 to pass within 100 miles of that point in September, of which only 2 made landfall in the US, the rest recurved well east. The two exceptions are Hugo and Georges (1998). Georges moved through the heart of the Greater Antilles hitting every island along the way. It is the furthest south of this grouping in the Caribbean as well, so a track south of the islands would be unprecedented
