Sorry no update for yesterday. Needed a day away as I'm in the middle of an eleven day stretch at my real gig. :-)
Ophelia got her act together yesterday deepening into a category 3 storm very quickly after being upgraded to a hurricane in the morning. By Air Force Reserve Hurricane Hunter recon there was a decrease in pressure from dropsonde measurements of 24 millibars in 3 hours by around 8 am on the 30th. This was an indication of RI (rapid intensification). The graph below is of the SATCON winds and CI number which is the Dvorak classification of a system. You can see the uptick in winds overnight from the 29th to the morning of the 30th.
