The dynamical model consensus from the National Hurricane Center had Kat moving anywhere between Appilachicola and NO. The path being quoted by the NHC was somewhere EAST of Pensacola.
That said, those models almost uniformly shifted west early Saturday.
The Mayor of NO was a moron for NOT having the wheels in motion beforehand on at least Friday, more like Thursday..
The model shift to New Orleans and vicinity occured with the 12Z runs on FRIDAY, (models coming out around noon Friday) not on Saturday...and have remained steady ever since.
Nope on the latter, go back and follow my links, I give a timeline with a supporting link of evidence for each. One of them was this one:

Look at the projected coordinates for the 4pm Friday bulletin from the NHC. One is 30.0, 88.5, which is just south of Pascagoula, MS and about 90 miles east of New Orleans.
