Must be Silly Season. I put down the wrong number on the advisory (shame that WUnderground doesn't put it in like they do for the discussions), the NHC uses an estimated pressure with AF304 in and a fresh VDM at 10:19 pm Eastern and then puts down 2 different numbers. Let's see if the current VDM holds...

Oddly; the pressure is up even as the 700 mb pressure altitude is down. Movement over the last 48 minutes due west (270 degrees) at 22 mph.
