Looks like the eye will be temporarily obscured by that burst of convection, although there seems to be plenty of time for it to wrap around and have the eye re-open. 85-95 kt at landfall seems to be getting more likely.

Recon is at 93.9W. Not much longer until it arrives.

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.

I wouldn’t say plenty of time. Three to four hours at most.

Are you talking about the storm arriving at the coast or the plane arriving?

I meant there’s not plenty of time for the eye to reopen after the convective burst before landfall.

What time is she supposed to make landfall? I thought the landfall was delayed by the NHC?

Okay, a decent amount of time.

Radar shows the western part of the eye only 11-12 miles from Padre Island.

By the time it's all said and done, 968mb is looking quite realistic. Should be right at the cusp of Cat. 2. Another note, these overshooting tops might also be indicative of new towers beginning to fill the eastern eye wall and a further tightening up.

appreciable lack of symmetry in the eyewall in terms of updraft strength (< 40 dBZ masked out)
