Depends on where they live, if they have a well built home away from water with no trees near the house then they will be ok, though they may have to deal with a extended period of no water/power etc....also if they have medical needs etc they may want to leave.....if they live in flood prone areas of have tons of trees around the house then they need to leave. Hotels and such will fill up if they havent already in all the inland towns....most people inland die from trees falling on them in homes or vehicles and trying to cross flooded roadways....
