Re: Tropical Storm Barry forms in Gulf of Mexico

What in the world is this spinning thing that came out of the convection and swirled back around? For a while I thought maybe "this" was the center of circulation, as the center has been so vague to me. But it circled around another circulation. I've never ever seen anything like this in any of the countless storms I have watched.
That is one of Barry's many mesovortexes, and probably the most prominent one thus far. Agree that it could become the dominant LLC now that it is tucking under the deepest convection and has a chance to lock up with the mid-level center. Otherwise, it will have been the most impressive mesovort spinning cyclonically about the center thus far.
Should this mesovort link up with that deep convection and the mid-level center (which has been south of the surface center), it could lead to a period of more rapid intensification and possibly tug the TC more to the southwest or even south, for a bit, before the west to northwest to north forecast track resumes.
