Bumpy Ride: Katrina and the Waves
The song goes something like this:
Do you know what it means to miss new orleans
And miss it each night and day
I know I’m not wrong... this feeling’s gettin’ stronger
The longer, I stay away
About 3 million people are missing home as they have been evacuated. Nearly 500,000 in NO proper. New Orleans, as we all know by now, sits below sea level.
If that first image didn't do anything for you then think storm surge and take a look at this image followed by this. The latter states that Category 4 storm surges can produce 13 to 18 foot surges. Katrina is a Category 5, I believe.
(BTW, the song above is Louis Armstrong not Katrina and the Waves)
