They just showed a shot of some interstate (I have no idea which one or at what point) but traffic was not moving at all. I think that would be worse than being on the 5th or 6th floor of a tall building or even on the 3rd floor of a rowhome.
I think I'd get out of my car and hike!
How many miles inland does one have to be to be safe from the surge?
I dunno. On the NOAA forecast they show it going as far in as northern 'Bama as a hurricane.
Mayor or N.O. just said they've been updated that it has 175mph sustained winds and it's only going to get worse because of the heat and humidity associated with the area.
