Fronts from the west will be replaced by Tropical Waves from the east. Smart sailors will keep their Wx watch eastward through November.
The day may start with a light predawn shower and end with a possible late afternoon or evening shower. But if the gradient wind has a southerly component in it, Caribbean heat and moisture will build Cumulo Nimbus in the mountains during the day. When daytime heating subsides due to western cloud cover or the setting of the sun, storm cells may roll down to the coast and slide off the lee sides of the capes. If they do, it will occur between 6 p.m. and midnight, after which all goes clear.

Rising warm air creates most storm cells. These rotate CCW. Down-spikes from upper air occassionally create CW rotating cells. You will feel warm humid air preceeding the CCW cell but cool air from the CWs. If the harbor gets straddled by two cells, one CW and the other a CCW, up to 50 knots N or S wind can result.

Banks north of us — Bahamas, Caicos, Turks, Muchoir, Silver and Navidad — reduce and diffract the swell, so it shall differ from the swell in the forecasts. Experienced north coast sailors can use this knowledge to "lengthen" otherwise short windows from port to port along the coast.
