Caribbean: A shear line is causing some fast-moving showers across the Windwards Islands. It has weak support from an upper trough. Most showers are light to moderate but a few have been heavy and there are isolated lightning in some. Barbados and Saint Lucia recorded 45mph and 46mph gusts this morning.
For the Windwards, expect some more breezy showers today and as the shear line weakens some occasional light to moderate showers continue Thursday and Friday.
Seas have been rough with some areas in open water 8-11 feet continuing today. By Thursday areas of 7-10 feet and Friday a slight improvement 6-9 feet.
Edit: I should add that the persistent locally rough seas can cause coastal beach erosion and temporary coastal flooding during high tides in a few locations.
Trinidad and Tobago received copious amounts of rainfall from September to November, with torrential rainfall in October and November 2022.

There is no concern for dryness at this time. The outlook for the next three months, December-January-February 2023 shows all areas are likely to be free from dryness in the short term.
