I read the TWD and this is what it had to say (they tend to mainly be observational):
A MIDDLE TO UPPER LEVEL LOW CENTER IS NEAR 10N57W. CYCLONIC FLOW AROUND THIS LOW CENTER COVERS THE CARIBBEAN SEA AND INLAND SECTIONS OF NORTHEASTERN SOUTH AMERICA...AND THE ATLANTIC OCEAN FROM 4N TO AT LEAST 20N AND POSSIBLY A BIT MORE TO THE NORTH BETWEEN 50W AND 65W. ISOLATED TO WIDELY SCATTERED MODERATE SHOWERS AND LOCALLY STRONG THUNDERSTORMS FROM 5N TO 12N BETWEEN 52W AND 63W. THE CARIBBEAN SEA FROM I9N52W TO 9N63W.
It just appears to me that it is barreling into the Caribbean and already pulling some moisture from the tropical wave+91L. I want to know the implications of how it could interact with the tropical wave and the high that is over the central Caribbean. Remember there is no vorticity currently at all with the tropical wave.
BTW on the NRL site, they have switched the image of 91L to the other tropical wave in the central Caribbean, so I'm guessing that 91L has been mostly absorbed there, but NRL is still going to refer to it as 91L?
Oh...I see... well, in that case.. not sure what the implications will be but in the hierarchy of atmospheric phenomenon, believe it or not, .the u/a low will always win... If it barrels along and tumbles into the western caribbean, it would be shredding the convective elements and absorbing them into the circulation core of the u/a vortex, as well as damping out the more typical upper level wave structure in the atmosphere - speaking in terms of the central Caribbean wave that is....
As for Beta, with more stowed momentum and development she'd fight off the impending shear quite a bit but would eventually subcumb by being attenuated until it was too weak to fight any more and it too would get gobbled alive; that is, should the unlikely occur with the u/a low, that it would careen smartly into Beta's vicinity...
...the models do not really show this feature too well and so it is unclear if/what/when/how it will interact with any activity further down the line. However, with a deep layer subtropical ridge N and NW tending to gain amplitude, it would probably tend this feature on a continued W or perhaps slightly WNW heading.. It would interesting really, because it would likely then have to slow down near the Puerto Rico to Cuban Archipelago area and spin for awhile - if not spin down.
