** = the 4 that later hit the CONUS
So, 4 of these 33 later hit the CONUS or 12% of them. The rest either missed or dissipated in the open ocean. A decent number actually dissipated.
The 4 that hit:
1. Inez (1966): 9/21 genesis ~10N, 35W; hit FL Keys
2. Gloria (1985): 9/16 genesis ~13N, 24W; hit NC OB, NE US
3. Georges (1998): 9/15 genesis ~10N, 25W; hit FL Keys, MS/AL/FL Panhandle
4. Lili (2002): 9/21 genesis ~10N, 45W; hit LA
Will TD #10 be the 5th since 1960 and add to the 12% that hit? I still highly doubt it and this feeling is supported by the 12Z ICON, UKMET, GFS, Legacy, and CMC. But I'll obviously continue to watch since this is far from a done deal being this far out.
Statistically speaking, I guess there are two ways to look at this Larry. Climatology and current model trends definitely support a harmless recurve. Statistically though, 1 out of every 8 of these buggers hit the CONUS, but the last 12 in a row haven't. We're overdue.
