The Trinidad and Tobago Meteorological Service says a tropical wave that's expected to pass over the region on Sunday, has a chance of developing cyclonic activity within the next 48 hours.
The announcement came as part of an outlook issued by the Met Office today, from Thurday through Sunday.
It states that tonight will be mostly hazy with the odd shower mainly after midnight.
Thursday is expected to be generally sunny and hazy conditions despite a few brief showers.
Friday will see an increase in moisture content over the area is expected due to some low level convergence.
As a result, cloudy periods with showers are expected with the chance of a few thunderstorms.
On Saturday, a slight decrease in moisture is expected and sunny and breezy conditions are expected with intermittent showers in varying localities.
However, the Met Office notes that on Sunday, a Tropical Wave axis is expected to pass in the early hours of the morning.
Cloudy conditions with showers and possible thunderstorms can be expected.
It says the National Hurricane Center is keeping an eye on this Tropical Wave as it believes that there is a 30% chance of cyclone formation within the next 48 hours.
As the Tropical Wave moves closer to the Lesser Antilles, conditions are expected to become less conducive for cyclone development.
However, the Met Office says it must be noted that this wave will still bring moist and unstable conditions into our area.
