What you need to know
— What: A surface to low-level trough is forecast to move across the Southern Windwards, including Trinidad and Tobago on Saturday night through Sunday, coupled with deep, tropical moisture from the Intertropical Convergence Zone. In addition, favorable upper-level divergence and low-level convergence is forecast to lead to periods of rain, isolated to scattered showers, and thunderstorms. Locally heavy rainfall is likely, favoring Trinidad.
— Where: Through Monday, both islands are forecast to experience isolated to scattered rainfall, with minimum rainfall totals ranging between 25 and 50 millimeters, favoring the western half of Trinidad and across Tobago. Higher rainfall totals are expected across the eastern half of Trinidad, potentially extending into central areas of Trinidad, with likely totals ranging from 50 to 100 millimeters and highly isolated totals peaking at 175 millimeters, favoring eastern coastal areas. Gusty winds (45-55 km/h) are likely, with higher gusts across Tobago and northern Trinidad (exceeding 55 km/h possible), accompanying heavy showers/thunderstorms across both islands.
— When: The TTMS issued the Adverse Weather Alert from 11:00 PM Saturday, December 6th, 2025, through 6:00 PM Sunday, December 7th, 2025. Rainfall is likely to continue into Monday.
— Impacts: Street/flash flooding and localized ponding are likely in heavy downpours, accompanied by gusty winds likely exceeding 45 km/h and gusts exceeding 55 km/h possible, favoring Tobago and areas that experience thunderstorms. These wind gusts, combined with heavy rainfall, may lead to fallen trees/utility poles/lines and landslides, as well as localized wind damage and agitated seas. Smaller watercourses may become overwhelmed by repeated rainfall, particularly by Sunday night across northeastern Trinidad.
— What Should You Do: Secure loose outdoor objects. Motorists and residents in areas prone to flooding or landslides should remain alert and exercise caution. Be aware of your surroundings and changing weather conditions. Take necessary precautions to mitigate potential impacts. If you encounter flood waters, turn around. If you hear thunder, head indoors. For those in flood-prone areas of northeastern Trinidad, review your flood safety plan if flood waters rapidly rise.
