From the latest VORTEX remarks section.

Sea Level Pressure Extrapolation From: 925mb

Using Google Earth this location is just over 75 miles north of the center. Over water but still a strong wind.
It could be due to the winds running up over the water after passing over the Yucatan Peninsula. There were two measurements near the same speed adjacent to each other.

Once the Center moves completely over the BOC Alex could generate some rather long swells in the GOM.
Present position is roughly 700 miles SSW of the Oil Spill.
