Looks like a TUTT cell to the northwest is causing subsidence and interrupting the poleward outflow preventing extreme intensification.

Oh dear. Now watch JTWC and Dvorak play catchup. Category 4 at best and due to it's small size, wouldn't rule out a 5. Where is recon again?

Interestingly EURO and GFS has little to no intensification from here and on out until it passes the NMI with the latter even suggesting some weakening.

95 kt is probably too conservative for a storm with a +20 C eye. I’d say 105-115 kt is better, but Bualoi is probably not stronger than that because of its very lopsided CDO and practically nonexistent surrounding convection.

Bualoi has become less lopsided with more flaring convection, but it looks like the eye will be briefly obscured as the CDO tries to improve.
