Re: NATL: MELISSA - Hurricane - Discussion
Estimating out the heights, I certainly think this is sub-900 now - perhaps by a fair bit. The last peak run had 2,308m at 697.2 mb (and that was 903 mb).

Re: NATL: MELISSA - Hurricane - Discussion
Keep in mind that this AF plane's extrap pressure on the last pass was too low: it was extrapolating 903 mb, when two dropsonades from different aircraft confirmed 907 mb.
So hold your breath once you see the pressure, until the dropsonade confirms it.

Or the AF plane could just not broadcast extrap pressure and we can wait for the dropsonde apparently.

I know there's reliability questions but 163 knot SFMR is beyond impressive.

Re: NATL: MELISSA - Hurricane - Discussion
Pressure not calculated. However, using the previous set and the decrease in heights, that would be an extrapolated 899 mb. Now we wait for the dropsonde.

Anyway, NE quad has 162 kt FL, similar to SW. Some other recent passes also had surprisingly high FL winds in the SW quad as well.

Such a mixed bag of feelings right now. I am both in awe, and terror. Its a difficult watch.
Each frame, the storm keeps improving. Prayers for Jamaica

Re: NATL: MELISSA - Hurricane - Discussion
Now, what to go with for the intensity? The dropsonde earlier confirmed a spot peak of 151 kt, while the flight-level winds support about 150 kt. I'd go with 155 kt, but a case could be made for 160 kt as well.

Re: NATL: MELISSA - Hurricane - Discussion
Of course the barometer wasn’t working this time lol. Hope they got a good drop in. I see they circled around a bit in the eye.

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.

Re: NATL: MELISSA - Hurricane - Discussion
Melissa reminds me of Milton at peak intensity...except Melissa is going to strike at or near that intensity. It seems like the core is wide enough to cover about a third of Jamaica or so. that eyewall swath is going to look like e-f4 tornado damage most likely...unless we get some sort of miracle weakening...and even then the storm is so strong it could fill a good bit and still be a monster. 2025 saved the worst for last.

This one is in until 0530Z I believe. The next one after that leaves at 0800Z.

4 AM NOAA.
The current AF plane has an exit time of 0530z (1:30 am EDT) for a 6-hour-long mission, so it should do a few more passes (if I understood it correctly).

They are well past the center, and I don't see a drop from when they were in it
Edit...903
