Summarize:

Canned food is the only kind acceptable for an event such as a hurricane; again, check the expiration dates to make sure the food is fresh. Always have these supplies on hand so that you can respond whenever an emergency arises. Try getting canned food that doesn't require any added water or milk, such as Progresso. Fill up the bathtub with water if you decide to stay home. An average bathtub full of water holds enough water for about three days. It also makes it possible to flush the toilet using a bucket. There is a lot of water in the hot water heater of your home. An average 150-liter water heater has enough water to keep a single person alive for a month. See here for details. An average person needs about 3.5 l of water (one gallon) per day. Pets (dogs) need about 1.75L of water per day. Cats need much less water. Do this as the storm enters your area and you settle down for the long haul. Eat perishables first in anticipation of the power going out. Fill your fridge and freezer with bottled water and sealed non-perishable items. The more full your freezer is, the more items there are to retain the cold and keep the overall temperature down. The same applies to the refrigerator. Store as much water and fluids as you can in your fridge so that if the power goes out, it will retain the cold longer; hopefully in time for the power to turn back on. Put all the ice that you have in your freezer into plastic bags. Fill all spaces in your freezer with bags of ice. Freeze water bottles, too. See How to keep foods frozen during a power failure for more details. Be sure that you are well supplied with any prescription drugs that you or your family takes on a regular basis. Some insurers will not honor refills until the last refill is nearly used up or has run out. If necessary, drugs must be purchased without insurance; weeks may go by without the ability to get refills, putting your health at risk. If you're in hurricane season, always have extra medication just case a storm comes in and all the pharmacies close down. Have the supplies to make it through if you and your family are trapped in your house for a week without access to electricity, running water, and stores. These materials include things such as light sources (powered by battery or hand crank), a manual can opener, a first aid kit, a NOAA-compatible radio, and hygiene products.

Many supplies in the disaster kit can be taken if you choose to evacuate by car. There will need to be smaller portions of food and water because of the lack of space in the transport. But there are some extra things you'll need if you drive away from the storm. Flares Physical maps Jumper cables Extra cans of gas This is to ensure the supplies you've stocked in case of emergency are both well stocked and fresh. You don't want to find yourself faced with an emergency and figure out that you're not prepared to face it. Keeping a checklist that has all the items categorized and dated helps with this process. Inflate airbeds to ensure they don't need patching or replacing. Use a battery tester so you know all your stored batteries still have a full charge.
Buy enough food and water to last a few days. Prepare your fridge and freezer. Have your prescription medication. Make sure that you have the necessities. Take your supplies with you. Check your disaster kit every few months.
