It's actually SUPPOSED to be heading NW tomorrow.
There isn't a single model with a landfall west of Eastern Louisiana and Katrina is already significantly N of that one...
Once you get a strong, well developed storm, really the model consensus these days for a 48 hour forecast is never so drastically wrong so as to have Katrina hitting Texas.
I would hope so however I will still monitor,They predicted days ago the NO was in absolute no danger.
