Sadly, many stayed in their homes. The news services said that if you haven't evacuated by now then "hunker down you've made your decision". Should have been get out and run for your life. So far 1 refrigerated truck has arrived with 60 body bags. This isn't going to be enough. Everyone needs to contact the Salvation Army or Red Cross to see what you can do.
Fla, costal residents should thank G*d that the predicted 17' storm surge did not happen, thousands would have died had 18' of water rolled into Charlette bay and coatal plains that surround it.
At that point, there's no place to run to, hence the advice to hunker down.
