Beach:
That buoy is at 79.0, very far west (actually, southwest, I think) of the low associated with 92L, so it likely has nothing to do with the low associated with 92L. (And the NHC wrote that there is a weak low associated with 92L, so the fact that one exists would not be a revelation, anyway.)

Are you referring to the rotation over Fla. visible in the water vapor loop, instead of to 92L? If so, I believe that's an upper level low, but hopefully one of the experts will chime in on that. (Actually, I just looked at the WV loop; the apparent circulation over Fla. is clockwise.) The light west wind at the buoy you gave the link for could be related to that feature, but likely is unrelated to any feature visible on that water vapor loop. Could just be a light wind associated with a storm or another transient weather feature offshore there.
