When a hurricane, tornado, blizzard, or severe thunderstorm strikes, you may be without power, water, or access to stores for days. Learn exactly what to stock in a storm preparedness kit to keep your family safe and comfortable through any weather emergency.
Why Every Home Needs a Storm Preparedness Kit
Severe weather events are becoming more frequent and intense across the United States. The average power outage after a major storm lasts 3–7 days, and in remote or hard-hit areas, outages can extend to 2–3 weeks. During this time, stores may be closed, roads may be impassable, and emergency services may be stretched too thin to respond to every call. A well-stocked storm preparedness kit transforms a survival situation into an inconvenience. The kit serves you during hurricanes (7+ days of potential isolation), blizzards (roof collapse risk and impassable roads), tornadoes (sudden shelter-in-place with debris risk), severe thunderstorms (flash flooding and power loss), ice storms (prolonged power outage with freezing temperatures), and heat waves (grid overload and rolling blackouts). Every dollar spent on preparedness returns multiples in avoided stress, medical emergencies, and property damage. The time to build a kit is now, not when a storm warning is issued—stores sell out in hours once a watch is announced.
Step-by-Step: Building Your Storm Kit
Start with the container: a heavy-duty plastic tub with a lid (18-gallon size, $10–$15 at any big-box store), a rolling cooler for mobility, or a dedicated emergency backpack for grab-and-go scenarios. Step 1: Assemble the seven core categories in your shopping list. Step 2: Purchase water—buy commercially bottled water in individual 1-gallon jugs (easier to handle and ration than a single large container). Step 3: Stock a 3-day food supply per person, selecting only items your family will actually eat. Step 4: Build or buy a complete first aid kit and add prescription medications. Step 5: Purchase lighting—at least two flashlights (LED, with spare batteries), headlamps for hands-free use, and LED lanterns for room lighting. Step 6: Add communication tools—NOAA weather radio with hand crank, battery-powered AM/FM radio, and a whistle. Step 7: Pack sanitation and hygiene supplies. Step 8: Store layers of clothing and sturdy shoes per person. Step 9: Add tools—multi-tool, duct tape, plastic sheeting, work gloves, and a fire extinguisher. Step 10: Place the kit in a designated, accessible location known to all household members.
When to Call a Professional
While building a storm kit is a DIY task, certain storm preparation tasks require professional help. Call a handyman or general contractor for installing hurricane shutters or impact-resistant windows, trimming large trees or removing dead branches near the house, securing loose siding or roofing before a storm, installing a whole-house generator with a transfer switch, mounting a storm shelter or safe room in your home, and installing sump pumps with battery backup for flooding. Call an electrician to install a generator interlock kit on your panel, add an exterior emergency disconnect, install surge protection for your entire home, or replace an old electrical panel. Call a plumber to install a sewer backflow preventer, add a water-powered backup sump pump, or winterize exposed pipes. Call a roofer to inspect and repair storm-vulnerable roof sections. Professional storm preparation costs $200–$5,000 depending on scope but is far cheaper than emergency repairs after a disaster.

Special Considerations for Specific Storm Types
Tune your kit to the storms most common in your region. Hurricane zones: add extra tarps (20x30 ft), rope (100 ft), sandbags, plywood for window boarding, and a plan to fill your gas tank before evacuation. Know your evacuation zone and have a route mapped. Tornado zones: add bicycle or construction helmets for every family member (head protection is critical against debris), a mattress to shelter under, and sturdy closed-toe shoes stored near the shelter area. Know your safe room location (interior basement or ground floor windowless room). Blizzard zones: add hand warmers, extra blankets or sleeping bags rated to -20°F, ice melt, snow shovels, and winter-rated vehicle emergency kit. Know frostbite and hypothermia symptoms. Flood zones: add waist-high waders, life vests, waterproof document bags, and elevate your kit storage. Know your flood risk and flood insurance status (standard homeowners insurance does not cover flooding). Wildfire zones: add N95 masks, goggles, fire-resistant blankets, and a go-bag ready for immediate evacuation.
Drill and Rotation Schedule
A storm kit is worthless if supplies are expired, batteries are dead, or no one remembers where it is. Conduct a household drill every 6 months: set a timer and have everyone gather the kit and meet at the designated shelter or meeting point. Time your response—if it takes more than 5 minutes, reorganize the kit for faster access. During the drill check flashlight and radio battery levels, test the NOAA weather radio reception, review the emergency contact list and update if needed, verify that all family members know utility shutoff locations, and practice turning off gas, water, and electricity. After the drill, rotate food and water supplies. Replace any consumables used in the drill. Adjust clothing for seasonal changes (add warm layers before winter, include extra water before summer). Review your family communication plan: out-of-state contact numbers, meeting points, and alternate shelter locations. Update any medical changes or new prescriptions. A 30-minute drill twice a year keeps your family truly prepared.
Frequently Asked Questions
Every storm kit needs seven core categories: water (1 gallon per person per day for at least 3 days), non-perishable food (3-day supply per person), first aid kit, flashlight with extra batteries, battery-powered or hand-crank radio, multi-tool or wrench for utility shutoffs, and a whistle to signal for help. Beyond these basics, add waterproof matches or lighter, emergency blankets, dust masks, plastic sheeting and duct tape for shelter, moist towelettes for sanitation, local maps, and a manual can opener. Customize based on your climate—hurricane zones need extra tarps and rope, snow zones need hand warmers and snow melt, tornado zones need helmets and sturdy shoes. Store everything in a large waterproof tub or rolling cooler that you can grab in seconds. Keep a smaller version in your car trunk for alternate locations.
FEMA recommends 1 gallon of water per person per day—half for drinking, half for sanitation. For a 3-day minimum supply, a family of four needs 12 gallons. For a 2-week supply (recommended in hurricane and remote areas), you need 56 gallons. Store water in sealed, food-grade containers—commercially bottled water is best. Avoid containers that have held milk or juice (residual sugar promotes bacteria). Store in a cool, dark place and rotate every 6 months. If you run out of stored water, fill bathtubs and large containers before the storm hits (this gives you a toilet flushing and sanitation reserve). A waterBOB (bathtub water storage bag) holds 100 gallons for $25–$35. Also store water treatment methods: bleach (8 drops per gallon, let sit 30 minutes), water purification tablets, or a camping water filter.
Choose non-perishable foods that require no cooking, no refrigeration, and minimal water. Top choices: canned meats (tuna, chicken, ham), canned beans and vegetables, peanut butter, nuts and trail mix, granola and protein bars, dried fruit, crackers, shelf-stable milk boxes, instant coffee or tea, electrolyte powder packets, and comfort foods like chocolate or hard candy. Avoid salty foods that increase thirst. Aim for 2,000–2,500 calories per person per day. Check expiration dates and rotate your stock every 6–12 months by eating and replacing items. Include a manual can opener, disposable plates and utensils, paper towels, and trash bags. For infants: formula, baby food, diapers, and wipes. For pets: 3-day supply of food and water, medications, vaccination records, leash, collar with ID, and a carrier.
Invest in multiple charging solutions for the inevitable power outage. A portable power bank (10,000–20,000 mAh) charges a smartphone 3–5 times and costs $20–$40. A solar charger ($30–$80) can recharge power banks during daylight. A hand-crank radio with USB charging port ($25–$50) serves double duty for information and charging. A car inverter ($15–$40) lets you charge devices from your vehicle (keep gas tank full before storms). For extended outages, consider a portable power station ($200–$1,000 depending on capacity) that can run lights, phones, and medical devices for days. Download offline maps, emergency information, and entertainment before the storm. Keep a printed list of emergency contacts and important phone numbers in your kit—phone batteries die.
Beyond a basic first aid kit, stock prescription medications (2-week supply minimum—ask your doctor for an emergency refill), over-the-counter pain relievers, antidiarrheal medication, antihistamines, and anti-nausea medication. Include bandages in multiple sizes, sterile gauze rolls, medical tape, antiseptic wipes, antibiotic ointment, burn cream, instant cold packs, tweezers, scissors, latex or nitrile gloves, and a CPR mask. For hygiene: hand sanitizer, moist towelettes, feminine products, toothbrush and toothpaste, soap, deodorant, trash bags for waste, and a portable toilet or bucket with seat lid (if sanitation systems may fail). For those with chronic conditions: blood pressure monitor, glucose test strips, insulin with cool packs, inhalers, EpiPens. Store medical items in a labeled, waterproof container. Check expiration dates every 6 months.
Store all critical documents in a waterproof, fire-resistant document bag or safe. Include identification (drivers licenses, passports, birth certificates), insurance policies (homeowners, health, auto, flood), medical records and prescriptions list, deed or lease, vehicle titles and registration, marriage certificate, social security cards, wills and powers of attorney, recent utility bills (for proof of residence), and home inventory documentation. Include digital copies on a password-protected USB drive or cloud storage. Write down PINs and account numbers—you may not have access to password managers during an extended outage. Keep cash in small bills ($200–$500) because ATMs and credit cards may not work. Include emergency contact list with out-of-state contacts (during regional disasters, long-distance calls may work when local networks are jammed).
Review and refresh your kit every 6 months—tie it to daylight saving time changes. Check food and medication expiration dates, water freshness (replace every 6 months), battery charge on power banks (recharge fully), flashlight and radio batteries, that clothing and shoes still fit family members (children grow fast), and that all documents are current. After each use during an actual emergency or planned drill, restock consumed items immediately. Update your kit when you move to a new home, your family composition changes (new baby, elderly parent moving in), you adopt a pet, you start a new medication or medical treatment, or you buy a new vehicle. Also update emergency contact sheets and save new out-of-area contacts. Seasonal adjustments: add hand warmers and snow gear in fall, umbrellas and extra water in spring, insect repellent and sunblock in summer.
