Having been through Hurricanes Ike and Rita, evacuated for Hurricane Andrew, and having worked an evacuee shelter for Hurricane Katrina, I think I can offer some tips on Hurricanes.
* Have at least 1 week of food and water for every person in your group. The government says at least 3 days, but shoot for at least 5 – 7 days. Depending on how much debris is on the roads, it could take 3 days for the road crews to get the roads open.
Evacuate low lying areas. Storm surge is no myth, get away from low lying areas and areas prone to flooding.
LED flashlights are better then old style bulbed flashlights. LED flashlights are more reliable then lights with old style bulbs, and LEDs have longer battery life.
Buy lithium batteries. Lithiums last longer then alkaline batteries.
Buy LED flashlights with long battery life and low lumens for inside the house. This is not a tactical situation, anything over 50 lumens can mess up your night vision. As you walk around the inside of the house, you do not want to blind other people.
Have a way to cook, such as a camp stove, or propane grill. Nothing boost morale like a good hot meal.
