ATL: MARCO - Remnants - Discussion

[ColdFusion]

I see the talk of shear, but for now, looking better than ever, and expanding.

[Kazmit]

Core has definitely gotten larger since earlier.

[DucaCane]

At this point, I was hoping to see a sheared/weakening storm. Not a good feeling here in SE Louisiana. Here’s to hoping the shear takes Marco out.

[xironman]

The subsidence on the west side it impressive, would think that on a sheared system.

[Ritzcraker]

Is it me or is Marco cutting off that giant rain band on his east side?

[tropicwatch]

If Marco can stay insulated, I could see further intensification, but if the shear wins out, the collapse could be fast. It will be touch and go.

This in a nutshell!

Looking like it is about to go
Also might be taking a due north turn.

[rolltide]

Would a stronger Hurricane bring it more north towards the Mississippi coast?

[GCANE]

Amazing how fast the CDO is expanding.
The Rossby Wave has been totally obliterated by Marco.

Getting a little uneasy here on Bama coast also. I know our MS neighbors are for sure?

[northjaxpro]

Would a stronger Hurricane bring it more north towards the Mississippi coast?

It looks like that may be already in the process of occuring.

Right as things are getting interesting, the hh heads to the barn. Next flight is a high altitude flight by NOAA and after that is AF scheduled to take off at 5 central time.

[DestinHurricane]

Marco still looks east of forecast track.

[GCANE]

50 to 60 mm/hr rain rate
5000 CAPE infeed from the Straits
Appears to be the main driver for strengthening.
Watching if they maintain, increase, or decrease.

...MARCO BECOMES A HURRICANE...
...LIFE-THREATENING STORM SURGE AND HURRICANE-FORCE WINDS EXPECTED
ALONG PORTIONS OF THE U.S. GULF COAST...

[GCANE]

Watching this increasing Theta-E area ahead of Marco.
A TC tracking into higher Theta-E air is a sure bet for intensification.

[GCANE]

Helicity also increasing

[Highteeld]

Pressure could be as low as 989 or 990 based off the final dropsonde pass.

[MississippiWx]

This intensification was anticipated today. It may get a little stronger throughout the day before shear increases. I’m just hoping to get a little rain out of it before it dries up.
