Based on the IR the weakening has stopped at this point and the structure is improving again. Something weird is going on if the pressure is still rising fast.
The eye has improved a lot in the last hour, kind of reminds me of Dorian undergoing RI. They could probably skip cat 3 on the next advisory and go straight to 4.
The Hurricane models show it strengthening very little until tomorrow afternoon when convection wraps around the north side, then it's bombs away, especially overnight tomorrow.
