Trinidad and Tobago was spared widespread inclement weather yesterday, although the country welcomed much-needed rainfall.
With heavy showers and thunderstorms moving across both islands from the early hours of yesterday, localised flooding was reported along the Eastern Main Road in Tunapuna, St Augustine and St Joseph, as well as along Farm Road, St Joseph, parts of Arima, and along the Couva Main Road, Couva.
Most areas saw between five and 15 millimetres of rainfall, with isolated totals exceeding 25 millimetres across parts of northern T&T.
The Trinidad and Tobago Electricity Commission (T&TEC) also responded to a fallen tree that brought down power lines along Saddle Road, near the North Coast Road intersection.
The Trinidad and Tobago Meteorological Service (TTMS) had placed the country under an Adverse Weather Alert (Yellow Level) from 10 pm on Sunday through 5 pm yesterday, which was discontinued yesterday afternoon. In the Met Office’s discontinuation of the alert, they stated, “The potential for impactful weather has decreased considerably.”
It noted, however, that there was still the possibility of activity continuing through this morning.
According to the TTMS, yesterday’s inclement weather was caused by an area of low pressure to the north-northeast of the Lesser Antilles, along with a trough in the mid-levels at our latitude, working together to draw lots of equatorial moisture, generally from the south-southwest to southeast, across Trinidad and Tobago and the Lesser Antilles. They added that due to winds converging near the surface, and clockwise-turning winds through the atmosphere, thunderstorms are developing and moving from the south-southwest to north/north-northeast across T&T and the Lesser Antilles.
While the inclement weather did not officially signal the start of the 2023 Wet Season, as no tropical waves or the Intertropical Convergence Zone have moved across T&T and produced measurable rainfall, the atmosphere is transitioning to a Wet Season pattern.
Today, the Met Office forecasts, “Mostly settled conditions to prevail after some isolated morning and early afternoon showers. There is a low to medium chance some of the afternoon showers could become heavy and or thundery.”
