The Met Office is advising of an active Tropical Wave east of Trinidad and Tobago that will pass over the islands in the next 24 hours.
The Met Office says the Wave has a 60% chance of heavy showers and thundershowers in some areas.
The following is a bulletin issued by the Met Office.
"An active Tropical Wave is currently located east of Trinidad and Tobago with accompanying showers and thundershowers.
Over the next 24 hours, as the wave progresses over Trinidad and Tobago, light to moderate showers are expected in varying localities, with a 60% (medium) chance of heavy showers or thundershowers in a few areas.
The main area of activity however, is forecast to remain east of Trinidad and Tobago today.
Street/flash flooding is likely in areas of heavy or prolonged downpours and gusty winds may accompany thundershowers.
Given the current state of some areas that remain inundated from the recent rainfall event, additional rainfall may exacerbate the situation.
Citizens are advised to be vigilant and cautious as they conduct their activities.
All necessary measures MUST be taken to preserve life and property from adverse weather conditions.
We wish to underscore that Trinidad and Tobago is not under any Tropical Storm Watch or Warning.
The Trinidad and Tobago Meteorological Service will continue to closely monitor this weather event and will issue another bulletin at 6 p.m. today or earlier if the situation warrants."
