What you need to know
— What: A surface to low-level trough has moved across the Southern Windwards, including Trinidad and Tobago, on Saturday night, coupled with deep, tropical moisture from the Intertropical Convergence Zone. In addition, favorable upper-level divergence and low-level convergence trailing the trough have led to periods of rain, isolated to scattered showers, and thunderstorms.
— Where: Through Monday, both islands are forecast to experience isolated to scattered rainfall, with minimum rainfall totals ranging between 12.5 and 25 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 25 to 50 millimeters and highly isolated totals peaking at 75 millimeters, favoring eastern coastal areas. This rainfall forecast is significantly reduced from the prior update. 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: Chances for street/flash flooding and localized ponding have reduced, but are still 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. Impactful flash flooding or short-lived riverine flooding is not expected.
— 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.

The Adverse Weather Alert
The Trinidad and Tobago Meteorological Service has maintained the Adverse Weather Alert (Yellow Level) at 2:57 PM Sunday, December 7th, 2025. The alert went into effect at 11:00 PM Saturday, December 6th, 2025, and remains in effect through 6:00 PM Sunday, December 7th, 2025, for Trinidad and Tobago.
This adverse weather event is very likely, according to the TTMS:
- Unsettled conditions are ongoing, with periods of rainfall of varying intensity expected to persist for the next several hours, along with a low to medium (30% to 40%) chance of isolated heavy showers or thunderstorms. Some areas across both islands have been experiencing breezy to gusty winds near showers. Settled periods are likely overnight, interspersed with light rain or brisk showers.
- Impacts: Gusty winds can occur in the vicinity of heavy showers or thunderstorms, which may displace loose outdoor items and agitate seas. Heavy downpours or prolonged rainfall can lead to street flooding and localized ponding, and may trigger landslides/landslips in vulnerable areas.
The alert’s color indicates the event’s severity and the likelihood of its occurrence. Currently, the alert level is Yellow. This means the hazards are very likely and the impacts are moderate for this particular alert. You should be aware of the hazards in your area, which include street or flash flooding, gusty winds exceeding 45 km/h to 55 km/h, falling trees, landslides, and agitated seas.
A moderate Adverse Weather Alert can result in possible injuries and behavioral changes, which are necessary to ensure safety. Minor property damage may also occur, temporarily disrupting income-earning activities and affecting several communities.
The Met Office advises the public to 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. Monitor official weather updates.
