TTMS declaration of the start of the 2023 Wet Season for Trinidad and Tobago

May 26, 2023 | News & Advisories

The Trinidad and Tobago Meteorological Service (TTMS) is officially declaring the start of the 2023 Wet Season for Trinidad and Tobago (T&T).

The official start to our wet season is marked by measurable rainfall (≥0.1mm) produced by a Tropical Wave and/or the Inter-Tropical Convergence Zone (ITCZ), both of which are the main weather-producing features of Trinidad and Tobago’s wet season.

The TTMS has been monitoring a Tropical Wave (TW), which moved off the west coast of Africa and slowly traversed the
Tropical Atlantic over the last ten (10) days.

This TW is currently affecting T&T, and 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, Friday 26th May, 2023, as at 2pm, Piarco measured 0.1mm of rainfall, with higher accumulations recorded in other areas. As the day progresses, this TW will continue to affect T&T, with the most enhanced weather remaining over eastern
offshore areas. Across both islands, there is a medium chance (60%) 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 that the TTMS is tracking, is forecast to pass early next week.
