Don't worry about it yet...keep an eye on the hurricane center, though. According to the public advisory they don't have up the results from sending the plane to investigate it yet. I know the 3 day forecast looks like it's cutting right across Florida. If it gets upgraded to TS they will call it Alfredo.

Usually they seem to move through pretty quickly, but I was in WDW for Frances and she was slow as molasses, the parks were closed two days for her. If they need to close the parks they will close them right before the storm is scheduled to hit, the storms are tracked very closely and they will know when that is. They'll open the parks back up as soon as possible.
