Wow, she's really weakened. Flight level winds down ~30 knots from peak, pressure up to 913 mb, and the eyewall's opened up. Eyewall replacement cycle, or is something starting to weaken her down finally?

Let's hope the weakening sticks!!
This is a classic, normal, eyewall replacement.
And you know that for sure from this line of the VORTEX:
M. C017-55
The "CO" means "concentric"...I.E. the bullseye of the old inner eyewall inside the new outer eyewall. 17-55 means the old eyewall is 17 nautical miles wide and the new eyewall is 55 nautical miles wide.
CNN calling it ERC.
I am wondering the same thing about the eye wall. Didn't it reorganize quickly overnight?
