Nope, that is the myth being put out by the governor and mayor to try and excuse why they were so slow to react. I went back and checked, and there were computer models predicting an LA hit as early as 7am Friday, strong model agreement on such by 2pm, at 4pm there was a weather service call to move the track west towards a S. Mississippi hit with possible further westward shifts, and by 8pm Friday night Gov. Blanco had declared a state of emergency.

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..
If I lived in Louisiana, I'd be real worried. The governor and the mayor of New Orleans do not look competent. In fact, the mayor looks and sounds as if he might assume the fetal position any moment. He says the dumbest things! The governor has that deer in the headlights look. If she's a republican, I'm ashamed, but I'd bet the farm she's a dim dem.
I won't be surprised if those people lined up to get into the dome riot before long. And just as troubling, the idiot partygoers still roaming Bourbon Street. I think they got looting on their minds.
This is very scary to watch.
