Locally, but brief, heavy rainfall and gusty winds are forecast. Heavier showers are likely to favour Eastern Trinidad. Across Tobago, partly cloudy skies and breezy conditions are occurring.

Throughout today into tonight, isolated to scattered showers are forecast to continue moving across mainly Trinidad. Heavier pockets are likely across Eastern and Southern parts of Trinidad. These showers are forecast to weaken as they progress westward. Gusty winds are likely in the vicinity of showery activity, up to 60 KM/H. These conditions are forecast to persist through the evening and into tonight. Across Tobago on the other hand, partly cloudy skies, with the odd isolated shower are forecast to interrupt a mostly settled but breezy day across the island.

These showers are due to two distinct surface to low-level shearlines across Trinidad and Tobago, with ample low-level moisture. Upper-level conditions remain unsupportive for enhancement of showers. As mentioned above, a few isolated heavy pockets may occur across parts of Eastern Trinidad, and accompanied by gusty winds.

Generally fresh to strong breeze is forecast (29-49 KM/H) for Friday mainly from the east. However, wind gusts in the range of high wind are possible (50-61 KM/H) across Trinidad and Tobago as the day progresses and the pressure gradient of the dominating high-pressure system tightens.
