What Food to Buy Before a Hurricane (the 48-Hour Cart)
August 27, 2026 · 4min read · Reviewed against FEMA & CDC guidance
Thirty-six hours out, the bread is gone, the bottled water is gone, and the batteries have been gone since the forecast changed. What's still sitting there, usually untouched, is most of what you actually want.
The panic cart and the useful cart are almost completely different, and the useful one is still available late. This is what to put in it.
Buy for no power first
Assume the power goes. Once you accept that, the shopping gets simple, because the question stops being what you like to eat and becomes what you would eat cold, out of the container, without apology.
That single filter does most of the work. It rules out pasta, rice and dried beans, all of which need water and heat you may not have. It rules in the no-cook foods sitting in aisles everyone walks past on their way to the bread.
Plan on 2,000 calories per person per day, and buy at least three days. A family of four over three days needs around 24,000 calories, which is a bigger trolley than most people imagine when they think "a few days of food."
The cart, per person, for three days
| Food | Amount for one person, 3 days | Roughly |
|---|---|---|
| Peanut butter | 1 jar (16 oz) | 2,500 cal |
| Canned beans or chili | 3 cans | 1,000 cal |
| Tuna or chicken pouches | 4 pouches | 700 cal |
| Crackers or tortillas | 1 large box or 2 packs | 1,200 cal |
| Granola or protein bars | 6 bars | 1,200 cal |
| Nuts and dried fruit | 1 lb total | 2,400 cal |
| Canned fruit in juice | 3 cans | 400 cal |
| Shelf stable milk | 2 boxes | 600 cal |
That lands a little over 6,000 calories, so scale it up if the forecast is ugly or if anyone in the house is doing physical work afterwards. Clearing a yard burns considerably more than sitting in one.
Buy for real preferences too. Three days of food nobody in your house enjoys is three days of everyone being slightly worse to each other, and coffee, chocolate and the cereal your kid likes cost almost nothing to add.
What to skip
Anything frozen. You are buying food for the period when the freezer stops working.
Family-sized cans. Nothing gets refrigerated after it's opened, so a big can of anything becomes one meal and a waste.
Dried beans, rice and pasta, at least as your main supply. They need a lot of water and a lot of heat. Useful the week after, useless the night of.
More bottled water than you can lift. Buy some, then fill what you already own: pitchers, pots, clean bottles, and the bathtub if a storm is genuinely coming. One gallon per person per day is the target, and your taps are free until they aren't.
Eat it in the right order
This is the part that quietly saves a whole cart of food.
Day one, eat the fridge. The USDA gives a closed refrigerator about 4 hours. Anything perishable gets eaten or cooked while there's still a chance of cooking it.
Day two, eat the freezer. A full freezer holds roughly 48 hours, a half-full one about 24. Keeping it shut is most of the job. There is more detail on the timings in the power outage food safety piece.
Day three onward, start on what you bought. Which means the shelf stable food is still completely intact when the outage turns out to be longer than anyone said.
Running it backwards is the common mistake. People open the emergency food on the first evening because it feels like the emergency, then throw out a fridge of spoiled groceries two days later.
The one thing people forget
A manual can opener. Every hurricane, somebody ends up with thirty cans and an electric opener.
Add a lighter, paper plates so you are not washing up with water you need for drinking, and a cooler with ice bought the day before. Ice is the last thing to sell out and the first thing people wish they had more of.
Keeping it useful after the storm passes
Most of this cart survives the storm and then slowly disappears. The tuna gets made into lunch in November, the granola bars go into school bags, the peanut butter is opened in a perfectly ordinary week. By next June the supply is half fiction and nobody realizes until the next forecast.
Provision Planner exists for the gap between what you bought and what's left. Add what's in the cupboard, and it works out how many days your household is covered for, using your real head count rather than a generic list. Then the shopping trip before the next storm is topping up four things instead of guessing at the whole cart again in a stripped store.
For the full non-food side of the trip, the hurricane supplies list covers the rest.
Frequently asked questions
- How much food should you buy before a hurricane?
- Plan on about 2,000 calories per person per day and buy at least three days, ideally seven. For a family of four over three days that comes to roughly 24,000 calories, which is a fuller cart than most people picture. Weight it heavily toward food that needs no cooking, because the power is the thing most likely to go.
- What food should you buy that doesn't need cooking?
- Peanut butter, canned beans and chili, tuna and chicken pouches, crackers, tortillas, shelf stable milk, dried fruit, nuts, granola bars, canned fruit in juice, and jarred pasta sauce eaten cold with cooked pasta if you have it. The test is whether you would be willing to eat it straight from the container at room temperature.
- How long does food in the fridge last during a power outage?
- The USDA gives about 4 hours for a refrigerator with the door kept shut, 48 hours for a full freezer and 24 hours for a half full one. Eat from the fridge on day one, the freezer on day two, and only then start on the shelf stable food you bought. Eating in that order is what keeps the cart you bought from going to waste.
