This weather is associated with the Inter Tropical Convergence Zone (ITCZ) situated to the south-east of T&T.
According to a media release from the Met Services, there will be an increase in wind speeds and cloudy conditions with periods of rain and showers, some of which could be moderate to heavy and thundery at times.
These conditions are expected to begin to improve later today.
The Met Services says given the expected conditions, citizens are therefore advised to be vigilant and cautious as they conduct their activities and to pay attention to daily public weather forecasts issued at 6 am, 10 am, 3 pm and 5.30 pm.
The Met Office emphasised that T&T was not under any tropical storm threat, watch or warning.
