Per the JB video, old rule from the days before computer models that his father subscribed to - mid August to mid October, pressure reaches/exceeds 1025 mb at Cape Hatteras, look out to the South.
I guess because pressure that high over Hatteras implies strong East winds over the SE US and Bahamas, and the Florida landmass causes slowing/convergence.
GFS shows big time Northeast US high pressure, and then falling pressure, kind of in the shape of an inverted trough in the next week.
GFS also shows Cape Verde season trying to refire, although it seems to be getting less likely something can get all the way across to North America/the islands in late September.
