uccellini, national director est weather service who has been with us here in the situation room. when the water is warm as it approaches florida, the power of this hurricane is only going to intensify. >> the source of energy for these storms is the warm oceans, and it's now approaching another warm pool of water, open water, less friction. so, this -- and we've seen now during the day, this tendency to start intensifying again. we are predicting now at 160 miles an hour at land fall in the northern keys. so, it's feeding off the energy of the warm ocean. it remains, it remains a very dangerous storm. we can expect destructive storm surge and heavy rainfall as it hits florida and moves up. the other aspect of this we need to emphasize is when you get this powerful storm making land fall, you have to worry about the tornadoes in that northeast quadrant of the storm.
