I have no updates to make to my thinking from last night on Katrina -- it is behaving exactly as I predicted thus far and still should make landfall about the time projected by myself and the NHC last night, i.e. sometime around midnight tomorrow night.
Similarly, I have no change to make to my projected track area, though I would tend to favor the eastern edge of that zone; this is in fact slightly west of the current NHC track, though I see no reason to go against their thinking at this time. Intensity might be a tick higher, though. Again, for the full details, see the entry referenced above.
If anything changes, I will post a full update. Otherwise, a minor update can be expected tomorrow with a full track projection for a potential second landfall slated for Thursday night -- or about the time of the first landfall.
