As this year marks the 15th year anniversary of Hurricane Katrina, I wanted to bring up something that has bugged my scientific mind since I was seven. Katrina was kept at a category 4 at landfall until December 2005, yet if you look at information that came from weather stations in Plaquemines Parish, the highest sustained winds were found to be 141 mph in Buras before the anemometer stopped working, shortly after landfall. I remember watching the radar as it came up the Mississippi Sound and it never lost it's structure, including getting a convective burst just east of St. Bernard Parish. By the time it made landfall at the border, according to my grandfather who was here in Pearl River, the winds were about 126, which correlates to what the NHC said. Can anybody shed light on this for me, and do you all think it possible that it is upgraded again when the re-analysis is done in a few years?
