A communication plan should work when normal routines do not. Ready.gov recommends planning how household members will receive alerts, get to a known shelter, follow an evacuation route and communicate with one another.
Write down household numbers, school or care contacts, medical providers, utility contacts and one out-of-area contact. Choose a nearby meeting place and another place outside the neighborhood. Give each person a paper copy and store a copy with the emergency kit.
Then test the plan. Send a message to the out-of-area contact, walk the meeting route and make sure children, older adults and people with communication disabilities can use the chosen method.
