8:00 AM Sunday 4th August 2019

Invest 96L continues on its northwestward track, as expected. The influence of this low-pressure system, combined with the approaching Tropical Wave 32, has influenced our wind regime across T&T.

Winds are calm to light, from the south. This means that our two main triggers for showers and thunderstorms today will be daytime heating and sea breeze convergence. Any convection to develop will be slow-moving and capable of triggering street flooding.

In addition, due to the overall motion of possible showers and thunderstorms, areas along Western Trinidad, southern facing slopes of the Northern Range, interior Central Trinidad, particularly along the Caroni Plains and the South Coast of Tobago would have the highest chances of experiencing showers and thunderstorms, in addition to street and/or flash flooding today.

As of 8:00 AM, mostly clear skies, with hot and sunny conditions forecast to continue through the morning, becoming partly cloudy by the late morning. Showers and thunderstorms are likely after midday, favoring the above-mentioned areas through the evening.

Lingering showers are forecast to remain across both islands overnight as Tropical Wave 32 nears closer to the Lesser Antilles.



7:20 PM Saturday 3rd August 2019

While no direct impacts are forecast from Invest 96L, locally heavy showers are possible through Wednesday as Tropical Wave 32 and the ITCZ moves across the islands, including Trinidad and Tobago.



11:45 AM Saturday 3rd August 2019

Partly cloudy to overcast skies are occurring across Trinidad with a few sunny areas across isolated areas in Trinidad and across Tobago.

Isolated heavy showers and thunderstorms are forecast by the afternoon across both islands as the ITCZ continues to affect T&T, with local climatic features (daytime heating, sea breeze convergence) to trigger additional showers across mainly Trinidad.

An isolated heavy shower is affecting parts of the North Coast Road, between Las Cuevas and the North Deck. Street flooding, downed trees possible.

Periods of showers and thunderstorms are forecast over the next 5 days, interrupting partly cloudy to mostly cloudy skies across T&T as both the ITCZ and TW32 affect the islands.

Street/flash flooding is possible, particularly during slow-moving heavy showers or thunderstorms. Gusty winds, thunder, lightning, and landslides are also possible.

No adverse weather alerts, watches or warnings in effect for T&T at this time from the Trinidad and Tobago Meteorological Service.
