Tropical storm Ophelia
11pm est
9-11-2005
Forecast 6#
The latest Ir satellite show Ophelia's inner core has faded. In which the system appears to be alot like tropical storm Isidor of 2002. In which dry air appears to have been pushed into the system. By southwestly winds shear. Which appears to have increased at 5 to 10 knots 3 to 6 hours.
Recon has found 74 knots flight level over northwest quad. In which no longer supports hurricane. A hurricane is at least 80 knots at 850 millibars. So I'm decreasing the winds based on this to 70 mph. Also pressure is now 981 millibars.
The system has been moving southwest at 5 knots...Which shows that the ridge/high to the north is much stronger then earlier thought. In which the 18z Gfdl has shifted from a outterbanks to a 33.0 north landfall. In which case from 35.5/36 north to around 33.0 north. Which is a shift of 150 to 180 miles to the left. The 18z Gfd makes landfall around 34.5 which is still a shift to the left.
Case in point if the southwest movement keeps up. It could go farther left.
To point the 12z Cmc shows a strong ridge to the north. Then breaks it down making landfall around 35 north. Since that is not likely to happen so fast it will be discounted. Also Lbar take the system into Ga. In which looks more likely then the CMC.
So I'm going with a mix of Gfdl/Gfs/Bamm models tonight. In which is a huge shift to the left. A landfall is being forecast by me near 34.0 north or near the SC/NC boader in 60 to 66 hours. Or Cape fear/Surface city...
With the slow movement(Upwelling) it is not likely to regain its central core. In which should keep it fairly weak. But the outflow over the northern quad/large size of the over all cirulation. Should keep the system a strong tropical storm. This is a chance it might regain cat1 hurricane if it moves faster. In which would allow it to move over warmer water to regain a central core.

not that I'm taking one side or the other but also Franklin was nearly a hurricane with pressures of around 1000mb and so was Cindy
