Trinidad and Tobago Met service issues riverine flood alert, yellow level in effect

Trinidad and Tobago: A strong and well-formed North Atlantic (Bermuda to Azores) high-pressure cell with a long fetch on its equatorial side, from the western coast of Africa to the Lesser Antilles, is pushing lines of convergence along our latitudes and causing perturbations moving from the east to west across Trinidad and Tobago.

Trinidad and Tobago: A strong and well-formed North Atlantic (Bermuda to Azores) high-pressure cell with a long fetch on its equatorial side, from the western coast of Africa to the Lesser Antilles, is pushing lines of convergence along our latitudes and causing perturbations moving from the east to west across Trinidad and Tobago. 

This, together with the influence of a mid to upper-level low area, which is over Trinidad and Tobago at this time, is drawing and converging moisture from our east and southeast. The resultant effect has been the development of periods of light to moderate rain or showers, which are being enhanced, in some areas, by orographic effects.

The forecast for this afternoon and tonight is for partly cloudy conditions with few showers. There is also a 40% (medium) chance of isolated heavy showers or thunderstorms. Some cloudiness will persist overnight with occasional showers. In the event of a heavy shower or thunderstorm gusty winds may occur in the vicinity.

With bouts of precipitation and the already waterlogged ground, it is expected that there will be street or flash flooding in some areas, and the risk of landslips/landslides is elevated in areas so prone.

Additionally, the Madden-Julian Oscillation (MJO), the major fluctuation in tropical weather on weekly to monthly timescales, is in a positive phase over our area, which can be a factor in the enhancement of convection and precipitation during the next ten (10) days. There is an expected increase in Saharan dust concentrations from mild to moderate at times over the next few days.

Trinidad and Tobago will witness partly cloudy with few showers.

There is also a 40% (medium) chance of isolated heavy showers or thunderstorms. Some cloudiness will persist overnight with occasional showers. Gusty winds and street flooding may occur near heavy showers/thunderstorms.
