Good Stuff Kart! We had a snow storm a few years ago that shut the entire city down for a week. We did good but one thing I didn’t prepare for was that with no electricity we had to eat every thing in the freezer. Some still spoiled.
The more freezers are packed, the longer they stay cold. If you have a few hours before big storm hits, pack in containers with water so they’ll freeze in case the electricity goes off. Also, pull out a big roast or two and cook them up so at least those are ready to eat. If it’s a snow storm - there’s your ready made refrigeration. First day with no electricity is ice cream day! After that is meat because that’s more expensive than vegetables.
Why didn't you bring the food outside once the freezer stopped being cool enough? If it was cold enough to snow, it was cold enough to freeze food (or at least keep it colder than in your house, which you presumably tried to keep warmer than it was outside).
Unfortunately, I will almost never have that option, being in South Texas. Of course, there's some advantage to the heat - we have a long growing season, and solar ovens are very practical (if I ever get around to buying or making one, that is).
