Here's something else I just noticed going back and looking at the wv loop...over the last five or six frames you can see the humidity clearing out of the eye, as the color changes down through the spectrum from red to grey-white.

Notice they kept the intensity at Cat 4 because of the winds. A tersely written special disc. I assume the plane will be sticking around to measure any record low central pressures, and to see if winds spin up to match the pressure. Guess the ERC is going to come hard on the heels of this intensification phase. Can hardly believe the eye went from 7 to 4nm. Is it even possible for it to get any smaller? Possibly that is why the winds cannot spin up as they normally would?
