I don't think Orlando will have much (any) weather impact from Gustav... The only major model that even shows it close to FL has a hit in the panhandle.... And this is a very small compact storm (will be ablut 90 miles wide when it gets it's act together...
Most models come together with a hit for this one between New Orleans and Lake Charles as a small but powerful 3 or low 4
HOWEVER... Here is some food for thought anout the one behind it
Disturbance 95L east-northeast of Puerto Rico
A tropical disturbance (95L) near 20N 58W, a few hundred miles east-northeast of Puerto Rico, has a closed surface circulation, as seen on this morning's QuikSCAT pass (Figure 3). This system could develop and be a problem for Bermuda by Monday, and the U.S. East Coast late next week. Visible satellite loops show that wind shear continues to play havoc with this system--strong upper-level winds from an upper level low pressure system to the west are pushing 95L's heavy thunderstorms to the east side of the center of circulation. Wind shear is a high 20 knots over 95L today, but is forecast to decrease below 5 knots on Thursday and remain below 15 knots for most of the remainder of the week. Dry air should not be a problem for 95L. NHC is giving 95L a medium (20%-50% chance) of developing into a tropical depression by Friday. Most of the models develop 95L, foreseeing a northwest track and a threat to Bermuda 4-7 days from now. The latest (2 am EDT) GFDL model run develops 95L into a strong Category 1 hurricane that passes very close to Bermuda on Monday. The HWRF model is more aggressive, predicting a Category 3 hurricane by Saturday, that then weakens to a Category 1 hurricane by the time it nears Bermuda on Monday. In the longer range, it appears that 95L will stall in the Bermuda area and move slowly, as steering currents collapse early next week. By the end of next week, the storm may scoot northward towards Canada (as predicted by the GFS model), or head west-southwestward into the Bahamas and Florida (as predicted by the ECMWF model). It is too early to guess which of these solutions is more likely.
