Ok, I am definitely not FORECASTING a central GOM hit, but was looking at the NOLA evacuation procedures. It says:
A. Evacuation Time Requirements
Using information developed as part of the Southeast Louisiana Hurricane Task Force and other research, the City of New Orleans has established a maximum acceptable hurricane evacuation time standard for a Category 3 storm event of 72 hours.
So depending on the speed, and if this continues to ramp up, misses land for the most part and winds up off the tip of Cuba in a few days, then conceivably, NOLA would have to start evac as early as the end of this week if it stayed in the cone. I dont have a good handle on when landfall would occur IF it took that route, but it seems that preparations would have to start kicking into gear relatively soon if it did.
Lots of ifs and assumptions, but hard not to at least consider that possibility.
