Dorian was in the low 940s when recon supported 130-140 kt, so a pressure this high has been seen before with winds of this magnitude.

I think Sam's small size allows for such high winds with such a high central pressure.

Take back what I said earlier. There isn’t a sustained weakening trend going on.


I was about to post the same thing, the CMG has returned with the new Convection . . .

I remember Matthew was 145 kt with a pressure of 942 mb.

This is the second time the storm was "weakening. Sam is really faking me out.

Keep in mind this is not official yet as the Best Track only has Sam up to 125 kts, though I think in reality it's closer to 130 kts. If NHC does indeed go with 125, this has to be the best 125 kts Atlantic system I've ever seen.

At least Sam is gaining latitude, might be headed for the weakness Peter will leave.

Assuming no pesky mid-level shear or EWRC interrupt Sam in the next 12-14 hours until that second recon plane arrives, they could find a Category 5. That’s quite a long time Sam would need to remain stable for, though, so I doubt it.

It’s hiccup this morning followed by RI was very similar to Eta. After its eye initially cleared out, it clouded up for a few hours and the CDO became jagged, just like Sam. Afterwards, the eyes of both storms cleared and they intensified to 130-135 kt.

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.

Does it seem like that Sam is trolling Recon like Eta 2020 did?

Looks like it finally cooled down those NW cloud tops. This is definitely making a run at Category 5.

I agree that 125 kt is too low based on that data. Blending the data would easily support about 135 kt.

NHC just want to stick to their forecast, they ignored the recon.

I'd go 140knt. Smrf 144knt and dropsonde. I like going liberal as it is impossible for a plane to simple all winds within a storm.

Thought it might be trochoidal motion but recon tasking is actually predicting it will be down around 13.1N at 49.7W.
