Wow, katrina is looking very impressive now. Almost as good as when Emily was at her strongest with 150 mph winds. Take a look here and scroll down until you see the animated infrared loops and you'll see what I mean. If this monster doesnt go through another ERC before landfall it very well could be a cat 5, because unlike waters where Ivan and Dennis went through before landfall, the gulf is still pretty deep as long as Katrina doesnt curve too far northward. With deep waters that only get hotter the closer you get to the coast, this thing is going to wreak some havoc.
