For the fourth straight day, locally heavy showers and thunderstorms are possible once more this afternoon, favoring western Trinidad. As a result, Trinidad and Tobago has been placed under a fourth Adverse Weather Alert for the fourth day in a row.
This activity is due to the Intertropical Convergence Zone across the area, combined with light winds, strong daytime heating, sea-breeze convergence on the west coast, and orographic effects in hilly areas, all typical features of the Wet Season.
What you need to know
— Rainfall: On Monday, while some areas may receive little accumulating rainfall, across both islands, up to 25 millimeters of rainfall is forecast, with overall lower accumulations across the western half of Trinidad. However, in isolated areas of western and northern Trinidad, localized totals between 25 and 50 millimeters are possible.
— Hazards: Localized heavy showers or thunderstorms are likely to lead to street or flash flooding, accompanied by gusty winds up to 45 km/h. These winds, combined with already saturated soils, may lead to fallen trees in elevated areas with possible landslides. In isolated strong thunderstorms, frequent lightning is likely, favoring the western areas of Trinidad. Seas may also become agitated in the Gulf of Paria.
