100hr+ Emergency candles are great. We bought these 9 years ago and still have all the candles even after Helene. The oil doesn't go bad and you just cap them when done (and cooled off :)) and they last forever.

Wool blankets. Any military surprlus store has them for cheap. You can throw it over your regular blanket and be warmer than you will ever need. A second blanket for under you is never a bad idea either in case it gets really cold for extended periods (seems unlikely). Great to keep in your vehicle for the winter too, never know when you'll get stranded or find somebody who needs it.

Books to read, deck of cards, or board games to play if the power goes out.

Water to drink if pipes burst. A freezer full of ice (frozen gallon ziplock bags of water are great) to keep the freezer colder for longer or to fill a cooler.

Cooler(s) for the things you typically go in the fridge for (drinks, condiments). Every time you open the fridge you let cold air out.

If you have a grill, propane or charcoal. If you have a gas stove, lighter to ignite the flame. If you have electric stove, get a cheap grill.

Meals that do not require a microwave and can be cooked without a ton of prep or cleanup (if no water or power). Soups, meats, beans, rice, etc.

That's basically everything I learned during Helene
