Add sanitation supplies including paper towels, toilet paper, hand sanitizer, and buckets & plastic trash bags (to store trash or human waste). Take plenty since you may be sick and need extras. Then double that amount.
Add specific "special needs" items including medicine, feminine hygiene items, diapers, and spare eyeglasses.
Add maps for local cities, your state, and surrounding states. Include backroads maps such as the DeLorme Gazeteer state maps. Also include a compass.
Add metal pan and matches for boiling water to purify it.
Add a contact list of phone numbers and addresses for every family member and friend who might evacuate with you, and everyone who might provide shelter to you.
Add earplugs. Shelters are noisy. The Houston Astrodome had public address announcements all day and into the night after Hurricane Katrina.
Add cellphone and charger, plus a charger that will work in your car. Add a satellite telephone if you are rich.
Add self-defense items such as pepper spray or firearms if you know how to safely store and use them. You won't be allowed to take them into a shelter but they may save your life in your home or on the road.
Print this list and keep it with your emergency supplies. Check it over before each hurricane season.
