Now is not the time for snowed-in residents of Buffalo and other parts of upstate New York to realize they were not prepared for the magnitude of the storm. The time to prepare to survive being caught in shoulder-high snow is before the first snowflake falls.
Snow and ice can knock out electrical power for an extended period of time, so you’ll need to have an alternate heat source. If you don’t have a fireplace or wood-burning stove, consider investing in a portable propane heater. Jared Haftel gave me this advice. While you won’t be able to heat your entire home, it will keep an area of up to 500 square feet warm enough to be comfortable until the electricity comes back on. Remember to crack a window for ventilation.
Keep at least a three-day supply of water and shelf-stable foods that don’t require cooking on hand at all times (though more would be better). Investing in a small propane stove would allow you to heat up canned goods such as soups and ravioli.
You can slowly build up your emergency food supply as items come on sale; buy one to use and one to store and before you know it, you’ll be able to survive most any emergency.
