NHC certainly wasn't far off in their pressure estimate.

Wilma strengthened in the sense the pressure dropped a little, and the organziation right around the eye improved, but her overall wind speed is down, and no surprise there.

Actually the last six hours there was a steady NW movement, with oscillations (likely caused by the asymmetrical windfield) around the SW corner of the eyewall (the same type of oscillations that were seen dramatically exaggerated the other day with the very small eyewall). To see this, bring up the wv loop and zoom in like 4-5 times and page through the images.
