I haven't taken time to read all of the responses but I want to add my 2 cents worth. Set up a plan for where to go, where to meet up and or WHO to call. Assign one preson, out of the effected area for everyone to contact, someone for everyone to call and check in so they can tell everyone else they are OK (need to do this way ahead of ANY emergency!). You will need someone that is avaliable to take the calls 24/7. Then everyone will need the contact number to call ASAP!

Also, when I created our families board, little did I realize how handy that would be. There was a woman in California , where my brother and family use to live that posted wanting news of them.... someone none of us knew. Wanting to know if they got out of the west bank of New Orleans and if thy were alright. A web sight like aimoo has, is easy to set up and CHEAP if you want to pay or free if you don't mind the pop ups. Our board has been a blessing through Katrina AND Eddies, and Brandons accident.
