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.
Keep a few pounds of seasoning/cure on hand. If the freezer goes down you can make jerky.
