Regarding the Tropics, the 00Z GFS and ECMWF models bring some remnants of Hurricane Eta north of Honduras, back over the far northwestern Caribbean late this week. It is not clear if this would be the old sfc circulation from "Eta" or some of its mid/upper remnants. Regardless, reliable model guidance shows a mid level low developing over the central Gulf coast which would push this system toward the E/NE over the NW caribbean with some (re)strengthening. Both GFS and ECMWF show an abrupt turn to the west near or over Cuba this weekend as strong upper high over the mid Atlc coast of the US blocks its northward progress. While highly uncertain, it should be noted that such a tight easterly pressure gradient between a strong high to our north and low pressure near or over Cuba would produce very windy conditions along the FL east coast with potential for bands of heavy rain pushing onshore and significant beach erosion.
as mentioned above in the last sentence, looks like Florida's east coast may be in for a significant coastal erosion event. Check out GFS next Sunday:
