Another round of widespread rain, scattered moderate to heavy showers, and isolated thunderstorms is forecast today, trailing yesterday’s strong low-level trough and ahead of Tropical Wave 05’s passage later tonight through tomorrow.
While overall rainfall totals today aren’t forecast to be as prolific as those of the past two days, additional rainfall is occurring on saturated soils, leading to quick runoff and exacerbating the flooding ongoing in several areas, as the Caroni River and its tributaries overtop. Other major rivers, as of 6:00 AM, were contained, but their tributaries are nearing threshold levels.
What you need to know
— Rainfall: Through Friday night (beyond the alert period), across Tobago and northern Trinidad, between 10 and 25 millimeters of rainfall is forecast, while across southern and central Trinidad, between 25 and 50 millimeters of rainfall is forecast, with isolated totals up to 100 millimeters.
— Hazards: With heavy showers and thunderstorms, as well as periods of rain, many of the typical Wet Season hazards are on the table for the next two days. Street and flash flooding is likely in heavy rain, showers, and thunderstorms, accompanied by wind gusts exceeding 50 km/h, and lightning during thunderstorm activity. With additional heavy rainfall, smaller watercourses may rise rapidly and overflow in some areas. Riverine flooding is ongoing across the Caroni River Basin. As soils become increasingly saturated, landslides are possible in elevated areas. Seas may become locally rough or agitated during heavy showers or thunderstorm activity.

The Adverse Weather Alert
The Trinidad and Tobago Meteorological Service updated the Adverse Weather Alert (Yellow Level) on Thursday, June 12th, 2025, at 5:55 AM for Trinidad and Tobago and surrounding waters. The alert went into effect from 2:00 AM Tuesday, June 10th, 2025, and has been extended through 4:00 PM Thursday, June 12th, 2025. Impactful weather is likely to occur beyond this alert period due to additional moisture and instability flowing across T&T, particularly with favorable low- and upper-level conditions, as Tropical Wave 05 moves across the country.
According to the TTMS, this “alert” status considers the possibility of the event occurring. This adverse weather event is likely, and the following are likely, according to the TTMS:
- Occasional showers and periods of rain are still expected today, along with a medium (60%) chance of periodic heavy showers and isolated thunderstorms.
- There is an increased risk of street flooding and landslides/landslips, particularly in areas with saturated soils. In the event of heavy rainfall, smaller watercourses may rise rapidly and overflow in some areas.
- Winds may become gusty in the vicinity of heavy showers/thunderstorms. These winds may further agitate sea conditions, displace loose outdoor items, and even topple unstable trees.
- A Riverine Alert – Orange Level is also in effect mainly for rivers in the Caroni River Basin.
The alert’s color indicates the severity of the event and the probability of its occurrence. Currently, the alert level is Yellow. This means that the hazards are likely, and the severity of the impacts is moderate for this particular alert. You should be aware of the hazards in your area, which are primarily associated with street or flash flooding, gusty winds exceeding 50 km/h, possibly 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 people in flood- and landslide-prone areas to remain alert, take necessary precautions, and monitor official updates throughout the day. Motorists and residents in flood-prone areas should avoid flooded areas and exercise caution. Secure loose outdoor objects. Take necessary precautions to mitigate potential impacts. Monitor official weather updates.
