Michael's pressure
Josh Morgerman posted his landfall map,according to his center landfall point the air Force Base that measured 920 mb was about 8 miles west of dead center. Pressure at landfall could be less than 919 that the last dropsonde measured about 1.5 hrs before landfall. Will be interesting to see what pressure is assigned when final report comes out.

Re: Michael's pressure
I think the 920mb reading was more like 3 miles from the dead center of the eye. Regardless, pressure could still be a couple mb lower than 919, especially considering the sharp gradient noted in the other eye pressure readings.

Re: Michael's pressure
The other thing to remember is that the lowest pressure may not always be bang in the center of the eye, it often wobbles around the eye to an extent, especially with vigorous convective blowups like we saw
Still given it was still undergoing RI into landfall, could have been a smidge lower still.

Re: Michael's pressure
My estimate is 916 mb. That's based on those theories mentioned (actually the AFB pressure was revised to 922 mb but was on the western edge of the eye) and the continued deepening after the 919 mb dropsonde about an hour before landfall.

If that is the case, that ties with Opal as the most intense October Gulf Of Mexico hurricane known. I am sure there have been more intense October Gulf Of Mexico hurricanes before satellite and thousands of years ago.
