CamSE-Wx Posted September 7, 2017 Share Posted September 7, 2017 GFS further south, speed about the same. More western of a path coming? Link to comment Share on other sites More sharing options...

Random Chaos Posted September 7, 2017 Share Posted September 7, 2017 On the GFS run, compare the size of the storm at present (hour 0) to two days from now (hour 48) - looks to double in physical size. Link to comment Share on other sites More sharing options...
SACRUS Posted September 7, 2017 Share Posted September 7, 2017 4 minutes ago, donsutherland1 said: Since 1851, there were 15 major hurricanes that formed in August or prior to September 15 and passed within 100 nautical miles of Irma's 11 pm position (19.4°N, 66.8°W). 60% made U.S. landfall. Areas of Landfall: Florida: 56% North Carolina: 22% South Carolina: 11% Texas: 11% Strength at Landfall: Category 1: 11% Category 2: 22% Category 3: 22% Category 4: 44% Major: 67% The Category 4 Storms were: Great Miami Hurricane (1922): 125 knots Lake Okeechobee Hurricane (1928): 125 knots Donna (1960): 125 knots Hugo (1989): 120 knots The spread of the 12z ECMWF ensembles continues to highlight the Florida-South Carolina area as being at highest risk of U.S. landfall. North Carolina is also a landfall site for some of those ensemble members. None make landfall west of the Florida Panhandle. A few take Irma offshore and avoid landfall. I still think Florida landfall is somewhat more likely than not and probably at similar strength to the three Category 4 hurricanes that made Florida landfall. Second landfall should occur at Georgia or South Carolina. Don, excellent summary. One note the Great Miami Hurricane I think you are referring to was n 1926. The others for reference Link to comment Share on other sites More sharing options...

yoda Posted September 7, 2017 Share Posted September 7, 2017 Looks like Irma is about to get pulled north (the start of it) between 66 and 72... am I seeing that right? Link to comment Share on other sites More sharing options...

The others for reference 3 of the 4 basically going right through or very close to both Miami and Tampa, dont think that is in play here but interesting to see.

yoda Posted September 7, 2017 Share Posted September 7, 2017 North turn made by Irma at 78... looks to graze SE FL with western eyewall perhaps... but eye should stay just offshore Link to comment Share on other sites More sharing options...

Considering the GFS is averaging being off by over 200 miles at 96 hours with this storm I think I'd just call a 20-30 mile shift east more or less the same.
