If you don't have room, store these in a box and keep them where you can quickly put them in your pockets. If you received a flood warning and your family had to evacuate, you might have time to throw together a few items or dash to a well stocked emergency shelter. It would be better to have a box or suitcase of supplies ready. A prepared family keeps enough emergency supplies on hand to meet its needs for a few days or, better, for a week. These items come in handy in an emergency even if you do not have to evacuate.
Some families keep their supplies in a basement shelter area or in a storm cellar, if they have one.
