Just for comparison, Katrina IIRC was a category 4 or 5 when it hit NO.

Katrina was barely a cat 3 and NOLA was on the week side of the storm when it hit. If it had been a cat 4 or 5 no one in NO would have survived it , none of the levees would have held .
All that damage was not caused by wind , it was caused by an one unkept levee breaking hours after the storm had already passed.

Thank You. I was about to post the same thing. Katrina was at that strength (4-5) when she was sitting in the middle of the GOMEX. She bombed out and hit shallow cooler waters during an ERC. She was all surge at that point...I don’t think winds were higher than 130 in Gulfport.
