New Orleans was almost completely destroyed. Let me make it short:
- costliest hurricane of all time
- Squashed New Orleans as a category 3 hurricane
- makes Hurricane Andrew look tiny (not from size) because Katrina was only a category 3 hurricane and Andrew was a category 5 hurricane and Katrina destroyed 3 times as much in money as Andrew.
- New Orleans was mainly flooded
- Katrina was tiny compared to some hurricanes
