There has been better vorticity, at times even drilling down to the surface with possibly gale force in very localized pockets, in the Caribbean itself. Low level northerlies in the Mona Passage (straight between Hispaniola and PR), as well as in eastern Hispaniola. What could be a touch of westerlies south of there.




When the cirrus shield thinned out some this afternoon, visible satellite loop had a low-level cyclonic circulation south of Puerto Rico, just north of a large cluster of deep convection. The buoy south of Ponce Puerto Rico NDBC Station #42085 reports dropping pressure, steady S/SE wind of 10-12 kts and SST 86.2F. The station near the west shore of Mona Island PR also reporting dropping pressure this afternoon with SST 87.4F (no wind data).
