[Gulfcoast]

Bring in yard flags, wreaths or anything else that might be blown around. Check flashlights and make sure you have batteries in the event of a power outage. Fill your car up with gas. Fill up containers (like empty milk jugs) with water and freeze. Have some bottled water and have some food in your pantry like a loaf of bread and peanut butter. Be sure to have some extra pet food. Refill and pick up any prescriptions. Be sure that shrubs/trees close to the house are trimmed - they will be less likely to break from the wind and they won't be rubbing against the house/gutters during the storm.

If there are power outages or downed trees blocking roadways you'll be all set.

(Editing to add: Make sure to charge your cellphone, too)
