COMPLETELY WRONG.
The last time the NHC track landfall was east of Mobile was 11AM Friday. At 5PM Friday the landfall was shifted to Eastern Mississippi, and at 11PM Friday the landfall was shifted to New Orleans, where it remained every advisory till landfall.
For whatever reason mythology about the NHC tracks being more wrong than they were seems to grow up after every storm.
Thank you for confirming what I thought I remembered.
