925 mbar extrapolated, and they still haven’t hit the exact center yet.
I hope they spin around and go back through the NW quadrant again, to confirm the maximum winds again.

I am only a meteorology enthusiast who knows a decent amount about tropical cyclones. Look to the professional mets, the NHC, or your local weather office for the best information.

Probably not, they only have fuel for two passes.

If so, the next recon plane should arrive when it completes, and this pass should determine if one is going on.

A 10 mph increase usually isn't enough to warrant a special advisory. They'll probably wait until 10 am EST.

They could still send out one of those updates and then wait for the full advisory for the discussion and forecast. Like they did earlier for Cat 4
