I have been waiting for this data.
Even though AMSU sounder could only capture half of it, it shows that Beta is a very very deep cold-pool shear-driven Tropical Cyclone.
Very much like Sally but even deeper.
It can sustain itself with pulsing hot towers.
Last hot tower showed a very large warm-core feature.
Appears to have enough energy, from the large CAPE pool, that sits off of Houston, to fire large towers.
There has been an interaction of the Rossby Wave with the LL vort.
The Rossby Wave created a high altitude vort that dropped to mid levels, aka 355K PV Anomaly.
Somewhat like a funnel cloud.
CIMSS 500mb shows this clearly.
Once the Rossby wave retreats, it is likely in my opinion, that the PVA will break off and stack with the LL vort.
High-helicity hot towers would facilitate the stacking.
If this indeed evolves as such, we could see a very quick intensification to a classical warm-core TC.
How it plays out from there depends on LL infeeds including sustained WISHE from the water and high TPW feeds.
Also depends on UL conditions and shear.
A classic warm-core is susceptible to shear.
But, if the deep cold pool is maintained, it may be able to push shear out of the way.
Need to see how this all evolves.
A big part of this is at the mesoscale level which the global models can't deal with.
Stay tuned.
