“The most impactful weather associated with the recent tropical disturbance has been significantly reduced and settled conditions are present in most areas.

Continue to exercise caution in flooded areas and refer to the Riverine Flood Alert from the TTMS,” according to the Trinidad and Tobago Meteorological Service.

The color of the alert indicates the severity of the event and the probability of the event occurring. Currently, the alert level is at Green, as the discontinuation was issued, and the certainty is possible.

At this level, according to the TTMS, there is a low risk to public safety, livelihoods, and property.
