I suspect that my "apparent circulation" may be illusory. With longer range radar imagery, especially, small-scale occurences such as storm cell propagation or shallow cells dipping under the radar beam can make it seem like there's broader rotation when there really is no such happening. Hence why I always use the term "apparent" if I'm uncertain. BTW, I think that "apparent circulation" is better than this over-used "eddy" term.
For the current convective situation, 92L is about to morph again. This time that new convective burst NE of Puerto Rico will likely become increasingly dominant, possibly elongating the disturbance NW to SE. It's hard to tell with IR imagery, but there might have been a recent outflow boundary emerging SE from the main convective region. If so, look for that MCS to diminish overnight with that more northern convective region becoming dominant. Obviously 92L is being driven by convective processes rather than any circulation core. So long the MCS's dissipate and reform without sustaining over a single area, the system is not really developing.
