What to Pack in Your Car Before Hurricane Season

Build a kit before the storm arrives, not when warnings start

A vehicle emergency kit for hurricane season is a set of supplies you keep in your car year-round so you have them if you get stranded, lose power, or need to evacuate quickly. The kit should include water, food that does not need cooking, a first aid kit, a flashlight with extra batteries, jumper cables, a phone charger, important documents, and cash. Most of these items cost little and take up minimal trunk space. The difference between having them and not having them can mean the difference between a manageable situation and a dangerous one.

South Carolina's hurricane season runs from June through November, with peak activity in September and October. During this period, roads flood, power lines fall, and gas stations run out of fuel within hours of a warning. If you are caught on the road when a storm hits, or if you need to leave your home suddenly, what is already in your vehicle is what you have.

Key Takeaways

• Keep one gallon of water per person per day in your vehicle, stored in a cool place and rotated every six months.
• Pack non-perishable food, a first aid kit, flashlight with batteries, jumper cables, and a phone charger before hurricane season begins.
• Store copies of your insurance documents, vehicle registration, and proof of residency in a waterproof bag in your glove compartment.
• Keep cash on hand because ATMs and card readers often stop working when power goes out during and after a storm.
• Check your kit every June and replace any expired items, dried-out batteries, or depleted supplies.

Water and food that lasts without refrigeration

Store one gallon of water per person per day in your vehicle. If you have a family of four, that means four gallons minimum. Water takes up space but is non-negotiable—dehydration happens fast, especially in South Carolina heat. Use food-grade containers, keep them in the shadiest part of your trunk, and replace the water every six months because it can become stale or contaminated.

Pack shelf-stable food that requires no cooking or refrigeration: granola bars, peanut butter crackers, canned fruit, canned vegetables, nuts, dried fruit, and protein bars. Include a manual can opener if you bring canned goods. Avoid anything salty or high in sugar that will make you thirstier. A small container of peanut butter and a box of crackers take minimal space and provide calories and protein. Do not rely on chocolate or candy as your main food source—they melt in heat and do not sustain energy.

First aid, light, and tools you will actually use

A basic first aid kit should contain adhesive bandages, gauze pads, antibiotic ointment, pain relievers, anti-diarrhea medication, antihistamine, hydrocortisone cream, tweezers, and scissors. You can buy a pre-made kit at any pharmacy for under twenty dollars, or assemble your own. Store it in a waterproof container in your glove compartment so it stays dry if water enters your vehicle.

Keep a flashlight with extra batteries in your vehicle at all times. A hand-crank flashlight requires no batteries but is slower to charge. Store the flashlight where you can reach it without getting out of the car. Test it monthly—dead batteries in an emergency kit are worse than no kit at all. Jumper cables or a portable jump starter can get you moving if your battery dies while you are stranded. A basic tool kit with a wrench, pliers, and screwdrivers takes up little space and solves common problems.

Documents and identification you need to keep accessible

Store copies of your vehicle registration, proof of insurance, and driver's license in a waterproof bag or plastic folder in your glove compartment. If you are evacuating and your home is damaged, you may also need proof of residency—a utility bill or lease works. Keep a recent photo of your vehicle (showing the license plate) on your phone or printed in the kit. If your car is damaged or destroyed, this photo helps with insurance claims.

Write down the phone numbers of your insurance company, your bank, and your closest family members. If your phone dies or loses service, you will not be able to look up these numbers. Store this list in the waterproof bag with your documents. Include your vehicle identification number (VIN), which you can find on your registration or on the driver's side of your dashboard where it meets the windshield.

Cash, phone charging, and communication tools

Keep at least one hundred dollars in cash in your vehicle, in small bills. After a hurricane, ATMs stop working, card readers go down, and gas stations may not accept cards. Cash is the only currency that works when the power is out. Store it in a waterproof container separate from your documents so you do not lose everything if one container gets wet.

A portable phone charger (power bank) with a USB cable is essential. Buy one with at least ten thousand milliamp-hours of capacity so it can charge your phone multiple times. Keep it charged at home and swap it into your vehicle every month. A car charger that plugs into your 12-volt outlet is a backup. If you have an older vehicle without a USB port, buy an adapter. A fully charged phone is your lifeline to emergency services, family, and information about road conditions.

Additional items that solve real problems

Keep a roll of paper towels or cloth rags in your vehicle. They dry windows, wipe up spills, and absorb water if it enters your car. A small container of hand sanitizer and wet wipes let you clean your hands when you cannot access a sink. A basic rain poncho or lightweight rain jacket takes almost no space and keeps you dry if you have to get out of your vehicle in heavy rain.

Store a small blanket or emergency blanket in your trunk. Even in summer, a stranded vehicle can get cold at night, especially if the air conditioning fails. A tire pressure gauge and a small air pump let you check and adjust tire pressure if a tire loses air. Tire sealant (a can that temporarily seals small punctures) can get you to a repair shop if you get a flat. A basic multi-tool combines knife, pliers, and screwdriver in one compact item.

Checking and rotating your kit before each season

Every June, before hurricane season officially begins, open your kit and check every item. Replace water that has been sitting for more than six months. Test the flashlight and replace batteries if they are dead or corroded. Check the expiration dates on first aid supplies and food. Throw out anything that is expired, dried out, or no longer usable.

After any storm or evacuation where you used items from your kit, replace them immediately. Do not wait until next June. A depleted kit is not a kit. Keep a simple checklist in your glove compartment so you remember what should be there. If you add items, update the list. The goal is to know, without thinking, that your vehicle is ready if you need it.

Frequently Asked Questions

Where should I store the kit in my vehicle?

Keep documents and cash in your glove compartment where you can grab them quickly. Store water and heavier items in your trunk where they do not take up passenger space. Keep the flashlight, phone charger, and first aid kit within arm's reach—under a seat or in a door pocket—so you can access them without getting out of the car.

Will water stored in my car go bad?

Water itself does not spoil, but it can absorb odors and bacteria from containers or air exposure. Replace stored water every six months. Use food-grade containers, keep them sealed, and store them in the coolest part of your trunk. Do not use containers that previously held chemicals or pesticides.

What if I have to evacuate and do not have time to gather my kit?

That is why you build it now and keep it in your vehicle year-round. When an evacuation order comes, your kit is already packed and ready. You do not have to think about what to grab—you just drive. This is the entire point of keeping supplies in your car instead of at home.

Can I use the same kit year-round or only during hurricane season?

Keep the kit in your vehicle all year. Emergencies happen outside of hurricane season—car breakdowns, accidents, and unexpected delays occur any time. A well-stocked vehicle kit helps in any situation where you are stranded or unable to leave your car.

How much does it cost to build a basic emergency kit?

A functional kit costs between fifty and one hundred dollars if you buy items gradually. Water is inexpensive, a pre-made first aid kit costs under twenty dollars, a flashlight with batteries costs ten to fifteen dollars, and a portable phone charger costs twenty to thirty dollars. You likely already have some items at home. Buy what you need over a few weeks rather than all at once.
