Pontchatrain surge was measure at 10-12 feet.
I just saw feed of 90 at Gulfport and the surge had lapped over US90 a bit.
I would guess as a now fully professional metorlogist that the surge at 45% NE from the eye to have been approximately 16 feet....mostly Waveland...not Pass Christian.
LOL...just kidding
Speaking of US90, someone else posted that its bridge/causeway from NO to the MS/LA border is now gone.
