New vortex found a central pressure of 999 mb in Stan, though with 26 knot winds at the surface in the dropsonde, the actual central pressure is likely somewhat lower. The dropsonde data has been interesting... one drop north of the center recorded 48 knot surface winds, even though the max flight level winds found so far are only 38 knots. The official intensity is up to 55 mph, which is somewhere between 45-50 knots.

The latest SHIPS guidance brings Stan up to near cat 3 intensity before landfall in about 48 hours.
