'You used the blizzard model, which is very familiar to people in the northern and mid-western states. I grew up in Ohio, so I can remember stocking up on staples and baking while we were snowed in for a week at a time. Although transportation was stopped, the utilities rarely were: we still had heat and electricity. I now live in Northern California where we're on constant earthquake preparedness, and I think the earthquake model is more like a Y2K scenario, where the possibility of being without electricity, heat, fresh water and transportation for some period of time is likely.
Here's what we're advised to do: stock up on canned and dried foods that do not need cooking and require a minimum amount of water to prepare. (Stock up on water, too, of course.) Pinto beans, for example, would not be a good choice because they require lots of water to clean, soak and cook and at least an hour of cooking time. But canned tuna would be good, as well as the sun-dried fruits and nuts that are available in health food and specialty stores in the fall and winter. A nationwide chain which specializes in dried fruits, nuts, trail mix, etc. is Trader Joe's.
Also, stores that specialize in recreation have prepackaged freeze-dried meals that need only a small amount of boiling water to prepare. This type of food is used by backpackers and mountaineers, who have to trek all of their food and cooking supplies into the wilderness and then trek them out, so it takes minimal space and is easy to prepare, while being high energy. A nationwide chain which specializes in this type of food is Recreational Equipment, Inc. (REI).
For people who live in urban areas, there are ways you can grow small amounts of fresh fruits and veggies year-round indoors, or in windowboxes or atriums (if you live in the Western or Southern states). Many apartment dwellers already have "gardens" devoted to flowers. It would be quite simple to convert them to lettuce, onions, tomatoes, carrots, etc. You could also can or dry (by sun or with a food dehydrator) fruits and veggies from the summer harvest, no matter where you live.
