good advice so far, especially about shutting off utilities at the main switch for each utility you have.

I would add that you should carry a couple recent electric bills with you with your name and address. It's not enough to have just a driver's license. There are circumstances where you could encounter roadblocks into your neighborhood and you don't want to hand out your driver's license to a soldier or other non-policeman if you don't have to. Much better to try to use an electric bill first and keep your license in your pocket.

Cash is king. Get a bunch. Be prepared to buy your way out of trouble if it arises. Keep the money spread out on your person so you don't have to flash the whole wad.

Don't let your gas tank get below half. Fill it up wherever possible. Credit cards and gas pumps don't work in a power failure. Carry a siphon.

Communication is important. Find a relative that is far from the storm's path to act as your "trip coordinator" since you will be separated from your wife. The coordinator can serve as a go between and message gatherer and also provide you with news, weather, routes, and other information. Give the coordinator all the details of you, your vehicle, and your plan before you leave and then work your plan and let the coordinator know of any changes as you go. Have a backup plan if the coordinator can't be contacted - namely, designate a church or other place to meet up with your wife at a certain day and time (assuming your house is completely destroyed and cannot be accessed).

The two most desired things after a hurricane are generators and ice. Plan accordingly.

Finally, stay safe. If you arrive at your damaged home with your wife and kids - sit them down and tell them that the number one thing is to NOT get injured. An injury like a nail through the foot or hand will cause your entire party to have to stop everything and address the injury and definitive care will not be a few minutes away like it used to be. Number one is DON'T GET INJURED. Go slow, think about each action - even little things like a child accidentally drinking water from a tap. Watch for nails and glass - hazards will be everywhere.

Good luck to you and your family and I wish you the best.
