I wouldn’t call it emergency food in a shelter, but I have spent days eating food in my house after a hurricane. Electricity out so trying to eat up any cold food, and winding up eating pantry food that wasn’t the greatest combination. Also, a lot of the pantry food isn’t great for health, or doesn’t taste good if it can’t be heated. I always try to store up on fruits and veggies that will last without very cold refrigeration like carrots, pears, apples, clementines, so I don’t eat only chips and other garbage.
Luckily, hurricanes we have warning. We stock up on pantry food all hurricane season, but add more if there is a storm out in the Atlantic that is headed towards us. We start eating freezer food 3 days ahead of a storm. Then a few to several hours ahead of the first bands I cook the frozen pizzas before the storm and any raw meat so it will last a day or two in styrofoam containers or coolers.
