Barometric measurement from Katrina

[dhweather]

While most of my Davis Vantage weather station was destroyed,
the console, inside the house, survived. I was able to extract
a minimum pressure from Katrina of 934MB / 27.59 inches.

Incredible! I was able to measure Katrina's barometric pressure when the cyclone was passing over Miami. It was 985.3 mb! Of course, not even close to yours!

27.92" in Hattiesburg

Going strictly on pressure, the pressure of 934 millibars at landfall I have
measured in Diamondhead is LOWER or equal to than the alltime
minimum pressure of these hurricanes:

Hugo 934
Charley 941
1926 Miami 935
1900 Galveston 936
1898 Brunswick 938
Hazel 938

I believe Hugo was 918. But thats odd your pressure is quite high. I thought Katrina was 927 at landfall. I guess you didnt go through the exact center.

Dhweather's house (and mine) was in the eastern eyewall. We're directly north of the St. Louis Bay.

I got the Hugo numbers from the NHC

We were in the Eastern Eyewall, as HurryKane noted.

934mb is the same pressure measured at the Slidell NWS office. Considering both sites outside the eye, I'd conjecure the pressure was a tad lower over central Hancock County, perhaps as much a 5mb lower....MGC

And that will be a great unknown as that geographic area is in the
Stennis Space Center buffer zone - nobody can or does live there.

Wow! That's incredible to have that reading.
Course, you probably wish you didn't. Hope you never see anything like that again.

Wow that is low. I've never recorded below about 950hPa here even with the all the baroclinic systems that move through in the autumn/winter.
