The Met Service has been monitoring a Tropical Wave, which moved off the west coast of Africa and slowly traversed the Tropical Atlantic over the last ten days.
This tropical wave is currently affecting Trinidad and Tobago.
Over the last several hours, parts of both islands have recorded measurable rainfall accumulations, thus signaling the official start of the 2023 Wet Season for Trinidad and Tobago.
For today, as at 2pm, Piarco measured 0.1mm of rainfall, with higher accumulations recorded in other areas.
As the day progresses, this Tropical Wave will continue to affect T&T, with the most enhanced weather remaining over eastern offshore areas.
Across both islands, there is a medium chance of heavy showers and/or thunderstorms with accompanying gusty winds.
With the passage of this Tropical Wave, the ITCZ which is currently south of 10N, is expected to gradually migrate northward over the weekend, increasing the potential for showers and isolated thunderstorms across T&T.
The next Tropical Wave the Met Service is tracking, is forecast to pass early next week.
