Katrina has definitely looked ragged this morning, but the latest visible loop is darn cool. You can easily see the concentric eyewalls, probably moreso than any sat loop I've seen before. This is not wishcasting, but wouldn't it be darn cool if the inner eyewall collapsed and we ended up with a storm looking like Isabelle did with an incredibly huge and distinct eye(again, only over the open water while it is harmless)? With this particular loop you can get 30 frames with each frame separated by only 5 to 10 minutes.... again, very cool. This NASA site rocks for hurricanes threatening the US.

In addition to the eyewall replacement attempt it is also very obvious the outflow is getting better each hour. It is good to the north, but in recent hours the outflow is really beginning to shoot outward toward the southwest.

I read the posts of several people who thought Katrina had turned wnw, but that appears to have only been a wobble for now as a due west movement of the eye has resumed. The eye will be leaving the Key West radar range in the next couple hours so it is satellite only until it approaches landfall.
