If it still looks the same in 6-10 hours track wise, I hope they start evacuating the city. They need at least 3 days to do it properly, so we are going to run out of time soon.
It'll never happen. Just look at the comments on this thread.
If Katrina hits NO as a Cat 3 or bigger, it will do so with all evacuation routes completely gridlocked.
The only thing New Orleans has going for it is the fact that long range forecasts are awful.
Sometimes.
