But the interesting thing was the pressure drop. The barometer dropped from 29.27 to 28.98 in 25 minutes. Quite impressive!
There’s a remark in surface reports called PRESFR, or pressure falling rapidly. This would qualify!
Naval Air Station New Orleans just gusted to 45 mph.
It looks like the eye may go directly over the city of New Orleans.
Landfall occurred about 4:15 between Cocodrie and Leeville on Terrebonne Bay, Louisiana.
