anyone been in a hurricane?
How far are you from the projected path? Close to the shore? Inland?
In my somewhat limited experience with hurricanes (NC, VA, New England--nothing "hurricane strength" but close), the two biggest problems you'll encounter are flooding and falling limbs.
If you're in a flood prone area or anywhere near the FL west coast (say up to 20 miles), Get Out! Otherwise, if you've seen standing water during past rainstorms in your area or have had localized floodings in the past...8-10 inches of rain is going to make it a helluva lot worse. This seems like common sense, but I see morons stuck in floods up to their car roofs on the news all the time because they didn't follow basic flood safety warnings.
As for limbs, well, you'll run that risk no matter where you are. Depending on how close you are to the path, there will be A LOT of flying stuff through the air, branches, street flotsam, etc... Plus, don't park near a tree on the street. Saturated ground+winds=fallen tree. Even in Northern VA (where I live) during Isabell last year, there were numerous people who had minor damage to their cars from falling limbs and the like. The wind blew over a couple trees in my neighborhood and a power line landed on someone's Benz. And that was a weak tropical storm by that point.
So, cover your car (if you can), find a garage, or just hope and pray. Scratches can be fixed (relatively) inexpensively or a tree falling on your car will be covered under comprehensive (Geico sends out notices to their subscribers in the hurricane path about what is and isn't covered). But floods....BAD. And I don't think your insurance will pay for that.
Either way, a car cover (even a crappy one) would probably be in order.
