The alert went into effect from 10:00 AM on Wednesday (today) through 6:00 PM. Impactful weather is likely to occur beyond this alert period due to additional moisture and instability flowing across T&T associated with the ITCZ and a trailing low-level trough through Thursday.

- There is a high potential for isolated heavy showers or thunderstorms today, particularly favouring hilly areas.
- Gusty winds can occur in the vicinity of heavy showers/thunderstorms and can lead to choppy seas.
- Heavy downpours can lead to street flooding and trigger landslides/landslips, especially along hillsides.
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 45km/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 securing 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.
