The Met Office is warning of periods of showers and thundershowers over Trinidad and Tobago tomorrow and on Saturday.
This is as a result of a tropical wave that is approaching the Caribbean islands, with a 20 percent chance of formation into a tropical storm over the next 48 hours.
The wave is moving in a west-northwesterly direction.
The Met Office says that the latest data shows that the most intense activity is likely to affect the islands north of Trinidad and Tobago.
It says street or flash flooding is likely in areas of severe downpours.
