I'll try. A ridge would be akin to a linebacker line. Nothing would get through. It would probably deflect to the west as you posted the winds are light easterly winds.

I just checked the Western Caribbean buoys and while they are reflecting a pressure drop the winds aren't above 20 mph at this time. Pressure drop could be a diurnal/ twice daily pressure drop.

ULL, upper level low in the BOC, Bay of Campeche, could draw 92L a bit further north. ( The Fujiwara Effect) .
I'm still trying to make some sense of all of the ULLs between Colin and 92L. If it help the models, several days ago, were forecasting 92L to track over the Yucatan Peninsula and into NE Mexico near Veracruz./ Tampico.
