Katrina Extremes, Revisited

Additional information has come out now regarding extreme weather recorded during Hurricane Katrina, and I have amended my previous report. The only things I am not sure about yet are the Buoy/CMAN pressure and wave readings because the National Buoy Data Center was taken out by the hurricane. Here are the stats:

Highest Wind Gusts (Over 100 mph shown):
Laurel, MS (Jones County Emergency Management) - 134 mph*
Pascagoula, MS (Civil Defense) - 118 mph*
Grand Isle Buoy (Off LA Coast) - 114 mph
Lake Ponchartrain, LA (NWS) - 114 mph
Belle Chase, LA - 105 mph*
Dauphin Island Buoy (Off LA Coast) - 102 mph
Southwest Pass CMAN (Off LA Coast) - 101 mph
Gulfport, MS (Emergency Operations Center) - 100 mph

*Unofficial readings. Official gusts are recorded by quality-controlled government stations. Unofficial readings were taken by amateur stations or government buoys. I am still researching the 134 mph claim and am not sure of its authenticity.

Highest Official Sustained Winds (Only Hurricane Force Shown):
Lake Ponchartrain, LA (NWS) - 90 mph
Southwest Pass CMAN (Off LA Coast) - 74 mph

**The wave height report was missing from the next hourly observation, indicating that it was out of range or the instrumentation was damaged. Wave height reports resumed at the next hourly observation. We may be able to find higher readings in the per-minute observations when the NBDC comes back online.

Big Branch, LA: 14.58"
Slidell, LA: 11.63"
