What you need to know
— What: A broad, deep-layered trough is forecast to affect the Windward Islands, including Trinidad and Tobago, from Tuesday evening through Thursday, coupled with deep, tropical moisture. In addition, larger-scale environmental factors are also favorable this week, leading to periods of rain, isolated to scattered showers, and thunderstorms.
— Where: From Tuesday night through Thursday afternoon, 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. Higher rainfall totals are likely across the eastern half of Trinidad and across Tobago, with likely totals ranging from 50 to 75 millimeters and highly isolated totals peaking at 150 millimeters, favoring eastern coastal areas. Gusty winds (45-55 km/h) are likely, with higher gusts across Tobago and accompanying heavy showers/thunderstorms across both islands.
— When: The TTMS issued the Adverse Weather Alert from 11:00 PM Tuesday, December 2nd, 2025, through 4:00 PM Thursday, December 4th, 2025. Conditions are forecast to settle by late Thursday as drier air moves in and upper-level conditions become less favorable.
— 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 with repeated rainfall, particularly by Wednesday night into Thursday.
— 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.
