Found this on another forum but I believe it is informitive.
The follow information was provided via several emails by a friend heavily involved in the New Orleans disaster of hurricane Katrina. I highly recommend that you read it and pay attention to the lessons therein.

I've had over 30 people staying with me since Sunday, evacuating from New Orleans and points south in anticipation of Hurricane Katrina. Only two families were my friends they told other friends of theirs that they knew a place where they could hole up, and so a whole bunch arrived here! I didn't mind, because there were six RV's and travel trailers, so we had enough accommodation. However, I've had the opportunity to see what worked - and what didn't - in their evacuation plans and bug-out kits, and I thought a few "lessons learned" might be appropriate to share here.
