Meet with your family and discuss why you need to prepare for emergencies. Begin by discussing the types of emergencies that are most likely to happen and what you should do for each situation.
Pick 2 places to meet - 1 that is right outside of your home and 1 outside of your neighborhood. All family members must know the address and phone number of the outside location.
Ask someone out-of-state to be your family contact. After an emergency it is often easier to call long distance than local. If for some reason, your family members cannot meet at the agreed location, they should call the family contact with their location.
