I thought this was interesting in the 5pm NHC disccusion.
"THIS CORRESPONDS TO A FALL IN CENTRAL PRESSURE AT A RATE OF 3.4 MB PER HOUR OVER THE PAST 7 HOURS OR SO...WHICH IS ONE OF THE MORE RAPID DEEPENING RATES WE HAVE OBSERVED. "
Can someone remember a recent hurricane strengthening as quickly or with a similar rate of pressure drop?
**I think rapid deepening would be better terminology. Sorry about the wordiness of my original post.
