This list is prepared as a service with no guarantees or endorsements. The most important consideration in preparedness is water. You should have a minimum emergency supply of 1 gallon per person per day for two weeks for drinking and other purposes. Store unscented Clorox or other water purifiers. Label all containers by content and date.
Toilet paper is always at a premium during disaster situations.
Store plenty of water for short and long term. Consider keeping old phone books. They're free and better than nothing. You should have food in the initial stages of an emergency that does not have to be cooked. Store things you will eat.
