Stock your storm shelter ahead of time with water, light, a weather radio, and basic supplies so a tornado warning never catches your family unprepared.
The middle of a tornado warning is the worst possible time to be gathering supplies. With only minutes of lead time, every second spent hunting for a flashlight or the dog's leash is a second you are not safely inside. The fix is simple: build a dedicated kit once and keep it inside or right beside your shelter, so getting to safety means walking in and shutting the door. Here is what Oklahoma families should keep on hand.
Storm Shelter Supply Checklist
-
Water and snacks
Bottled water and non-perishable snacks, enough for everyone for several hours. Rotate them once or twice a year so nothing goes stale.
-
A battery weather radio
A NOAA Weather Radio keeps you informed if the power and cell networks go down, which is common in a major storm. Keep spare batteries with it.
-
Flashlights and lanterns
Battery-powered light for everyone, plus extra batteries. Avoid candles or anything with an open flame in an enclosed space.
-
A first aid kit
Basic supplies for cuts and scrapes, plus a few days of any essential medications your household members rely on.
-
Sturdy shoes and helmets
Closed-toe shoes protect your feet from debris and broken glass afterward, and bike or sports helmets add real protection against head injuries, the leading cause of tornado deaths.
-
Phone chargers
A charged power bank keeps a phone alive for calls and emergency alerts when the outlets are out.
-
A whistle
If you are trapped or buried, a whistle is far easier for rescuers to hear than a voice and takes much less energy to use.
-
Important documents
Copies of IDs, insurance policies, and key papers in a waterproof bag, so you have them if your home is damaged.
-
Pet supplies
Water, a leash or carrier, and a little food if pets will shelter with you, which keeps them calm and contained.
Where to Store Your Kit
Keep the kit inside the shelter if it stays dry, or in a sealed, easy-to-grab container right next to the entrance if space or moisture is a concern. The key is that it lives in one known place that everyone in the household can find in the dark. A duffel bag or a lidded plastic tote works well, and a headlamp clipped to the handle means the first thing you reach is light.
If you have young children, walk them through where the kit is and what is inside during calm weather. Familiarity removes a lot of fear when a real warning comes.
Check It Twice a Year
Tie a quick supply check to the time changes in spring and fall: replace expired water and batteries, confirm your radio and flashlight work, and update any medications. It takes a few minutes and means your shelter is always ready, not just ready the day you stocked it.
Tailor the Kit to Your Family
The checklist above is a strong starting point, but the best kit reflects who actually uses the shelter. A family with an infant needs formula, diapers, and wipes. Someone who depends on daily medication should keep a few days' supply, rotated so it does not expire. Households with pets need a way to keep an animal calm and contained in a small space. Spend a few minutes picturing your family's worst night and pack for that, not for a generic emergency.
Comfort items matter more than people expect, especially for children. A small toy, a familiar blanket, or a deck of cards can make a frightening wait far easier to manage, and that calm helps everyone in a cramped shelter.
What Not to Store in a Shelter
-
Open flames
Skip candles and any fuel-burning lantern; an open flame in an enclosed space is dangerous.
-
Anything blocking the vents or door
Keep gear clear of the vents and the exit path at all times.
-
Perishable food
Use shelf-stable food and water, since perishables spoil and can attract pests.
-
Clutter you will trip over
Store the kit in one tidy container so the shelter floor stays clear.

The Bottom Line
The whole point of stocking your shelter ahead of time is that a tornado warning gives you only minutes, which is no time to gather supplies. Build the kit once, keep it in one known place inside or beside the shelter, and getting to safety becomes as simple as walking in and shutting the door.
Tailor it to your family, favor shelf-stable supplies and battery-powered light, and skip anything with an open flame or anything that blocks the vents or the exit. Then refresh it twice a year so it is always ready, not just ready the day you packed it. A few minutes of preparation now buys real peace of mind every storm season.
