The previous vortex message had a pressure of 958 mb, but HDOBs at the time it was taken indicated something closer to 955 mb. The recent drop to 952 mb probably wasn't as dramatic as 6 mb in 2 hours, but still an impressive drop. The most vigorous convection right now seems to be in the inner core and in the inner most of the outer bands, so some consolidation may be occurring. Flight-level winds around the inner core are still relatively weak, though the most recent Ike discussion mentioned that dropsondes indicated stronger winds closer to the surface in the inner core.
