From someone who's been through several big storms...
Good luck to all of you in the path and DO NOT take this lightly. We've been through many hurricanes and tropical storms and I speak from personal experience.
All of these storms were direct hits to my area:
Camille in '69 (Category 5), Frederick in '79, Elena in '84, and most recently Georges in '98 (HUGE tidal surge with that one, our refinery was under 4 - 6' of water and down for 3 months.)
Be careful, stay alert, stay informed, follow directions of the professionals, don't be a "cowboy" and try to "ride it out".
Remember, John Wayne was an actor.
