F Storm?

Note convective burst north of the island closer to the apparent surface circulation (see recent space-borne radar and San Juan radar) for the first time--deepest convection has been offset well to the south (mid-level circulation) until now--appears to trying to become more vertical of a system--have see if it persists.  Will now also have to contend with the mountains of Hispaniola--Puerto Rico has been disrupting it to some degree.  06Z GFS still shows Florida/Georgia as most probable (east or west coast??), but the track trend has been edging west for ~24 hours as the system has stayed on the weaker side (though certainly impressive visually).  Sooner it develops, the better for us as the trough over the northern gulf would pick it up earlier--conversely if it stays weak, it could just keep headed west--too early to say--will have to watch the model track trend through the day.  Waiting for next recon to see if we have a true surface low yet--last only found <5 knots west wind well south of PR (broad circulation).  Also watching the stuff behind it too--one of those could be a major.
