Katrina was a Cat 3 when it made landfall
Exactly, and we all have to remember it wasn't the wind that caused most of the damage, it was the storm surge. We also have learned that the Rigt side of the eye is the worse side. New Orleans was luckily on the Left side during Katrina. This time the path of the storm is placing New Orleans on that most destructive Right side. Not good at all if that path continues.
