There are many resources available online that describe what a family should discuss and rehearse prior to a disaster in their area. However, there is little consistency in the written content of these plans.
Do your own investigating and develop a comprehensive Family Emergency Plan that you could share as a resource with others. Make sure you include information about sheltering in place, out-of-area sheltering and contacts, evacuation routes in the home and in the neighborhood, resources for household members with disabilities and accommodations for their needs, and pets. Include a communication plan—how will members communicate with each other and with other family/friends in the neighborhood and in other parts of the area. Make sure you have members establish contact with someone outside the impact area as the primary contact with whom everyone checks in after the event.
