LI Phil,
After looking at that link, I think there may be something to the idea of that high up north pushing this system south...it sure looks that that is happening. I have been looking at the satellites, radar, and other data and it appears that Katrina is testing the models and the mets...I am thinking we may see her turn suddenly north sooner than expected also...maybe 6 to 12 hour...20 at the outside...but that is just based on the some of the things I see at this time...but this is 2005 and anything is now possible.....
