Interesting note on the 06Z NHC models.
At 48 hrs they have the wind speed at 123kts/ 141mph.
Somewhere between 26.8-27.3/ 88.4-90.4 offshore
At 72 hours they are forecasting 124 kts-143mph.
Somewhere between 31.0-32.9/ 84.7-91.0 well inland
That would appear to indicate an increase in wind speed before landfall. For the winds to be 1 mph above the overwater speed. Am I reading that right?
What I read is 120 knots shortly before landfall, then the next position is well inland at 75 knots.
Edit: latest IR image shows more southerly motion still.
Edit2: Looking at the last 2 water vapor images I see something coming from the north dropping down into south central Alabama - could this be the trough that will ultimately take Katrina away from its home in the hot GOM? Opinions anyone?
