For reference twobone...
As far as barometric pressure at landfall Katrina's pressure was 918 millibars which is third lowest for a landfalling hurricane in the Atlantic Basin. The 1935 Labor Day hurricane that hit the Florida Keys had a pressure of 892 millibars, Camille at landfall had a pressure of 909 millibars. So, Camille had a lower pressure at landfall(which by the way was that hurricane's lowest pressure recorded). However, Camille was about a third of the size of Katrina. As far as when Katrina was a category 5 hurricane in the central Gulf of Mexico 24 hours before it made landfall. It had a pressure down to 902 millibars making it the 4th lowest pressure reading in the Atlantic Basin. But the 902 millibars is the lowest pressure ever recorded for the Gulf of Mexico. The lowest pressure for the world was set with Typhoon Tip in October of 1979 with a pressure of 870 millibars. If you count all record low pressures for the world I believe Katrina is 7th lowest in the world. The lowest pressure ever measured in a hurricane in the Atlantic Basin was with Gilbert in 1988 with a pressure reading of 888 millibars.
