Here’s The 5-Day Weather Outlook For T&T — From Tuesday Through Saturday

According to the Trinidad and Tobago Meteorological Service (TTMS), the centre of the present North Atlantic high pressure cell is gradually drifting towards the far Eastern subtropical Atlantic, eventually reaching just to the Southeast of the Iberian Peninsula by Friday (31st January, 2025). This configuration is expected to continue to provide a long and generally straight fetch across the Tropical Atlantic, generating steady, moderate, near-surface to mid-level winds. A passing frontal system to the North, with a following and strengthening high pressure cell from the North-Northwest, is expected to induce a surface trough, creating low-level convergence and equatorial moisture build-up, in the tropical wind flow across Trinidad and Tobago and the Lesser Antilles by Wednesday (29th January, 2025). 

For this outlook period, the seas in the open waters to the near-East and Northeast of Trinidad and Tobago are expected to be mostly moderate, gradually increasing to rough, when moving further outward. Persons are advised to continue to monitor the sea conditions and always take precautions in marine activities.

The near-surface to mid-level winds are expected to continue to be mostly moderate during this outlook period. This is likely to produce generally breezy conditions, and at times could become gusty, especially in elevated areas or in the vicinity of any shower that might occur.

The Met Office notes that generally mild concentrations of atmospheric dust are present, with occasional brief fluctuations to moderate, until Thursday (30th January, 2025), when the concentration is expected to rise to mostly moderate. From Thursday, the dust concentration is expected to gradually rise to show a moderate to occasionally high concentration by the end of this outlook period. Further analysis is indicating that there are likely to be increased instances of high concentrations by Saturday (1st February, 2025). Persons who are sensitive to the changes in the dust concentrations are advised to take the necessary precautions. 

For most of this outlook period, there are likely to be generally fair conditions with partly cloudy interruptions at times, producing brief showers in varying areas across the Lesser Antilles. On Wednesday (29th January, 2025), an induced surface trough is expected to cause low-level convergence and equatorial moisture build-up over Trinidad and Tobago and the Windward Islands, with a medium chance for isolated heavy showers or a thunderstorm to develop. By Thursday (30th January, 2025), a noticeable drying out of the atmospheric moisture, together with a gradually increasing Saharan dust concentration, is to be expected.

Tuesday (28th January, 2025) 

• Across Trinidad and Tobago and the Lesser Antilles, patches of moisture advection are likely to interrupt the mostly fair and breezy conditions, with brief showers over varying areas. There is a low to medium chance for a moderate shower to develop, mainly near hilly areas during the late morning to afternoon. During the evening and night, there is a medium chance for a brief moderate shower to develop over Tobago and East Trinidad. 

Wednesday (29th January, 2025)

• A surface trough across the Lesser Antilles, influenced by a frontal system passing to the North, is expected to draw some equatorial moisture from the Southeast, across Trinidad and Tobago, the Windward Islands, and the Southern Leeward Islands. Partly cloudy to cloudy conditions are expected, with light or moderate showers over varying areas. There is a medium to high chance for the development of isolated heavy showers or thunderstorms, with the higher chances likely between early morning and early afternoon and over, but not confined to, Eastern coastal and offshore areas.

Thursday (30th January, 2025) 

• ​Moisture advection after the recent passage of a trough, together with varying surface convergence, is likely to produce a few partly cloudy patches with brief showers, interrupting otherwise fair conditions in varying areas. There is a low to medium chance for a brief moderate shower to favor hilly areas. 

Friday (31st January, 2025) 

• ​Generally fair conditions, with patches of moisture advection and varying areas of surface convergence are likely to produce a few partly cloudy patches, with brief showers in some areas. There is the chance for a brief moderate shower to favor hilly areas. 

Saturday (1st February, 2025) 

• ​Mostly fair conditions with patches of moisture advection and varying areas of surface convergence are likely to produce a few partly cloudy periods, with brief showers in varying areas. There is the chance for a moderate shower to develop, especially near hilly areas or during the afternoon. 

The TTMS said it continues to analyze and monitor all developments within the Area of Interest.

Please continue to pay attention to the latest forecasts, alerts, and information issued by the TTMS.
