An isolated thunderstorm north of the Maracas Valley is weakening as it progresses north of Trinidad with light to moderate showers across the North Coast of Trinidad.

Further east, scattered showers and isolated thunderstorms are approaching Eastern Trinidad, likely to move across Northeastern Trinidad and the northern half of Trinidad over the next 1-2 hours. Showers and thunderstorms are fairly slow-moving this evening so there is an increased risk of street flooding, particularly across Northeastern Trinidad communities.

An isolated cluster of showers is affecting parts of Southwestern Trinidad, including Debe, Penal, Siparia, and environs.

For the remainder of the Southern half of Trinidad, partly to mostly cloudy skies may be interrupted by an isolated shower, but no significant rainfall is forecast.

Across Tobago, isolated to scattered showers, generally light to moderate are to continue.

This activity is forecast to persist overnight.
