I have just finished looking at about 8 different loops. Although it appeared to be going almost due west for a while, I am seeing jogs to the sw just like you are, Steve. It's almost "stair-stepping" at this point. This morning it looked like it was going to make landfall near WPB (at least to my eyes), now it is further south near Ft. Lauderdale.
Also....NWS in Tampa is very concerned about Katrina. The latest disco urged people in West Central and South central Florida to not let their guard down.
I have a question: if this is only 45 miles due east from Ft. Lauderdale traveling at 6mph heading due west, why (according to NHC) would it be making landfall around midnite or 1:00am? If it's 1:00pm now, wouldn't they be expecting landfall around 7-8pm tonight?
I'll admit...I was never really good at math...so please feel free to correct me if I am wrong!
