I think it makes a lot of sense to store food and water for whatever kind of natural disaster is likely. The short answer is shelf-stable goods, such as canned meats, soups, vegetables and fruits. Also falling into that category are dry or canned milk, canned or powdered drink mixes, smoked or dried meat, cookies and cold cereal. Select foods that you and your family like to eat. An emergency is not a good time to experiment.
Most experts recommend storing at least a three-day supply of both food and water.
The general recommendation for water is one gallon per person per day. Food- grade plastic bottles, such as soft drink bottles, with tight fitting caps are best. Since power outages often accompany other emergencies, make certain to have an alternative method to heat your meals, such as a charcoal grill, which can be used only outside, or canned heat, such as Sterno, which can be used inside your home, the extension educators say. And for the same reason, you can't depend on your refrigerator or freezer to store your emergency food supplies. Use and replace your inventory of stored goods about every six months.
