Just got a chance to look at the satellite images.

Looking stronger, more symmetric, and larger, and appears to have strengthened in the last couple of hours. On visual, the "buzzsaw" appearance much clearer, the eye looking more like a Cat 5, and the area of the eyewall just surrounding it as well; seeing more smoothed appearance with those little ripples/crinkles all around. On Dvorak IR, has the appearance of a strong Cat 4 or Cat 5; buzzsaw appearance even more striking. Most recent image from 14:45 shows this most pronounced and the continued move towards complete symmetry in the core windfield. Also this image shows the stadium effect quite well, which means windspeeds have increased significantly since a couple of hours ago. The eye looks like it has tightened up (because of the stadium effect it still appears to be larger).

I am seeing some shear to the W and N, on the high winds of the outflow, but this doesn't seem to really be affecting the storm.

Like Katrina this storm has very strong spiral banding feature and the eyewall characteristics also seem to be very similar.

The difference in organization and growth of the core windfield between the 09:15Z and the 14:45Z images are striking on wv loop.
