Tropical Wave 64 Moving Across T&T, Thunderstorms Begin

12:30 PM Saturday 14th November 2020

The axis of Tropical Wave 64 is moving across the Lesser Antilles, with a mid- to upper-level trough enhancing showers and thunderstorms mainly east of the islands. However, showers and thunderstorms have begun to affect Trinidad, with persisting showers across Tobago.

Cloudiness, showers and thunderstorms to persist through the evening, which could bring gusty winds in excess of 55 KM/H, locally heavy rainfall triggering street/flash flooding and lightning.



Gusty Winds Move Across Tobago

11:43 AM Saturday 14th November 2020

Persistent showers and isolated thunderstorms have affected Tobago after midnight through midday, with between one half inch (12.5 mm) to 1.5 inches (37.5 mm) of rainfall recorded across the island. Higher totals occurred across Eastern areas. With thunderstorm activity, a wind gust of 65.5 KM/H was recorded at Scarborough at 11:43 AM.

Showers, Thunderstorms Developing Across T&T

6:00 AM Saturday 14th November 2020

The axis of Tropical Wave 64 is just east of T&T, along 59W. Showers are developing across eastern areas of both islands. Rainfall totals between half-inch (12.5 mm) to one inch (25 mm) have been recorded across Eastern Tobago, with isolated totals up to a half-inch (12.5 mm) across Eastern Trinidad over the last 6 hours.

Elsewhere across the country, mostly cloudy to cloudy skies are ongoing and forecast to persist, with brief showers and isolated thunderstorms throughout the day. Winds are forecast to predominantly flow from the east-southeast to south-southeast, meaning heavier shower and thunderstorm development will set up across northern and western areas of Trinidad, as well as eastern coastal areas of both islands. Rainfall forecast to favor the late morning through the afternoon (9:00 AM through 4:00 PM) and then again closer to midnight.

Overall rainfall totals today are forecast to be between 5 to 15 millimeters across much of the country, with isolated totals up to 50 millimeters, particularly across eastern parts of T&T. Street/flash flooding, gusty winds and lightning possible in heavy showers and thunderstorms.

These conditions are due to the passage of Tropical Wave 64 and a surface to low-level trough anchored across the Southern Windward islands. In addition, the mid to upper-level environment is expected to become slightly more favorable for convective development as the day progresses supporting occasional moderate to heavy showers. These conditions are expected to persist overnight.

However, as a more diffluent mid to upper-level pattern shifts east of the southern Windwards and strong westerly wind shear, much of the deeper convection is expected to remain east of T&T.
