This morning 7 is approaching Islamorada in the Florida Keys, building, but not quite with a low level circulation quite yet. There is an upper level low to the southwest that is probably slowing that down, but at the same time feeding mid level moisture into it. That low is moving away, and there are hints of west winds on radar and a few stations south of Islamorada. I suspect it'll develop around noon. Conditions are mixed for strengthening, but odds favor it staying a tropical storm before landfall.

The small size of the system does have potential for a round of strengthening tomorrow morning before landfall, so it'll have to be watched closely then, but the NHC's forecast is fairly decent.
