Very latest Vortex Data Message from @53rdWRS shows #Ida's eyewall now open to the NW, a 180-degree change from the NOAA pass an hour or so ago.
This indicates instability in the eyewall from the hot towers pinwheeling around the center.
Should close off and symmetrize soon.

Spinning up a hurricane’s eyewall is in some ways a lot like spinning pizza dough.
Initially you have an oblong blob with two hands (hot towers) working to get it spinning.

After some time, you can move your hands (hot towers) closer to the center of the dough once it’s spinning faster.
This reduces instability and increases symmetry

Eventually it’s developed and symmetric enough to spin smoothly around one single point.
