Jim,
Will all the bodies be able to be recovered on will they float out into larger bodies of water?
I'm probably not the right person to ask that question, but my understanding is that NO is like a soupbowl, and any water leaving is not going to flow out. It will be pumped out. Obviously, they'll have the pumps protected from anything being pulled into them, even if there were no bodies there. A tree branch could trash a million dollar pump.
If the water flows, sure the bodies would flow with it, regardless of where in the water column they are. That was a big problem in the tsunamis, and the main reason why huge numbers of bodies were not found. The tsunami roared in, crested, and then swept back out to sea, taking many bodies with it.
Hurricane storm surges are nothing like tsunamis. We think that, but actually, a hurricane storm surge is just a dome of water pushed in front of the storm. The circulation of the storm exerts downward pressure on the ocean. The ocean acts like a bowl of jello -- push down in one place, it rises up in another place. The harder the push, the higher the rise. [Edit: The storm surge is not moving hundreds of miles per hour like a tsunami; it's moving at the speed of the storm, and it extends way out in front of the storm, so the surge is gradual, unless the topography of the beach makes it break like a wave.]
Because a hurricane takes so many hours to pass by, you don't get the huge rip tide you get with a tsunami. You get water returning to the ocean, but much more gradually.
