Scott,
Basically speaking you are safer in a one story home if it has been built in the last 3 years, than you would be trying to evacuate to any place as of today. That is something that is relative to the landfall wind speeds. The higher the speed at landfall the more risk for anyone. The greatest threat from hurricanes before and after landfall is tornadic winds, no one can predict where, and flying debris which may have come from many miles away from you. The basic safe information is to stay away from your windows in a center room where there are no windows and hopefully at least one room between you and the outer walls of your home. Have flashlights, first aid kits, and cell phone if possible or other noise making object so that if the worst happens, you can be found as soon as help is available. We oldtimers in your area were just young chickens the last time anything of this magnitude happened here and frankly we were not in charge in those days of determining saftey. Follow your local emergency management recommendations and if you live in a prefabricated house or mobile home, leave when told to do so. A standard, housing development style or custom designed home built in the last 3 years will withstand good straight line winds with loss of shingles, etc. and if no trees or vehicles fall through the roof.( I am not being funny)
