Kat was category 4 windspeed and cat 5 pressure on landfall in MS. She was category 5 for both at landfall in South Louisiana. At least that is what I have read.

There's no such thing as "Category 5 for pressure" as pressure is irrelevant to giving a storm a Saffir-Simpson category. The pressures ranges you see given for S-S categories on charts are merely additional useful info.

And it was a Category 4 at first landfall in Louisiana.

We need to come up with a better scale for storms.
