ATL: GAMMA - Post-Tropical - Discussion

[GCANE]

Sorry for the late reply on the sift east relative to forecast track.
Had to run out this afternoon.
Anyway, red X is the last recon fix on the forecast track.

Short-duration hot tower firing off with lightning just north of the CoC

Recon indicates Gamma may have been decapitated. All convection is up around 24N, but the center appears to be well to the south. Maybe 125 miles south of the heavier convection. Haven't closed it off yet, though.

Yep, center well south of the mid-level vortex. Southerly shear and dry air have taken quite a toll.

Gamma moving n.e and seems to be growing. No?

[us89]

The convection being generated right now is quite impressive with cloud tops well below -80C.



However, it is sheared well north of the LLC, which is located at 22.8N/87.2W.

Pressure up to 1000mb on latest recon pass. Seems like the end is near for Gamma. That would open the door for Delta to become stronger in the gulf right?

Like Wxman57 said she is decoupling. See loop below you clearly see llc now moving away from mlc.

Infrared looks like the Zapruder film.
So now a weaker Gamma will most likely be pulled back WSW as Delta approaches Cuba.
And a regenerating Gamma in the BOC might keep the Delta track from shifting NNE later in the forecast.

Very high rain rate for a "decoupled" TC.
I would expect this is where the cold pool is.
Could fire for quite a long time and would likely condition the upper levels in the GoM ahead of Delta.
Would enhance the Anticyclone Rossby Wave Break and increase chances of intensification of Delta once it gets in the GoM.

While the LLC of Gamma meanders north of the Yucatán, the MLC and most of the rain is getting sheared NE towards the West Coast of Florida. Tropical Systems are fascinating.

If deep convection doesn’t return to Gamma soon, I would expect it to be declared a remnant low. Looks terrible this morning.

Gamma is to Delta as Marco is to Laura

Gamma is to Delta as Marco is to Laura

That's been an interesting theme this season coming in twos. A weaker storm paving the way for a much more powerful one

They did seem to come in pairs alot - Teddy and Vicky, Paulette (who's remnants are still with us) and Rene, the forerunner of Beta and Sally as well.

Sights can be be deceiving but to be honest, ex-Gamma doesn't look to bad right now. Weak spin but a lot of convection.

[us89]

Ex-Gamma is Delta's lunch.

[Blinhart]

Should start feeling the effects of Delta in the near future and just make Delta even bigger
