Adverse Weather Alert Discontinued For T&T

Adverse Weather Alert Discontinued

The Trinidad and Tobago Meteorological Service has discontinued the Adverse Weather Alert (Yellow Level) for Trinidad and Tobago. However, as we’ve been mentioning, adverse weather is possible from Wednesday through the end of the week due to the ITCZ, Tropical Wave 53, and favorable atmospheric dynamics.

Information from the Trinidad and Tobago Meteorological Service concerning the Adverse Weather Alert Discontinuation for September 29th, 2020.

According to the TTMS, “Most of the showers and thunderstorms are now well north of Trinidad and Tobago, so the threat of impactful weather has significantly decreased. Keep monitoring our updates, as another weather event is possible from Wednesday 30th.

Trinidad and Tobago is NOT under any tropical storm threat, watch or warning.

The color of the alert indicates the severity of the event and the probability of the event occurring. Currently, the alert level is at Green, as the Discontinuation was issued.

The Forecast

Overview: A surface to low-level high-pressure ridge is forecast to briefly strengthen, reducing atmospheric moisture and increasing wind speeds across the region, particularly due to the presence of a low-level jet. Tropical Wave 52 will move across the islands today but much of the shower and thunderstorm activity will remain north of T&T. Daytime heating and sea breeze convergence are may act as triggers for late morning afternoon shower and thunderstorm development, though precipitation chances remain low for Tuesday.


Forecast: A mostly hot and sunny day is forecast across both islands. By the late morning, partly cloudy skies are forecast to develop Trinidad. By 11 AM, isolated showers are possible, mainly across hilly areas, but by the afternoon, isolated thunderstorms are possible across Western Trinidad. Conditions are forecast to settle by the evening, with shower and thunderstorms possible by nightfall, particularly after midnight.


Marine: Seas are forecast to be slight to moderate. Generally, in open waters, waves between 1.0 meter and 1.5 meters are possible, particularly north and east of T&T. In sheltered areas, generally below 1 meter to near calm conditions.

Hazards: With mostly settled conditions, today’s high temperatures and heat indices will be the main hazard so particularly between 9:00 AM and 3:00 PM, stay cool and hydrated! In the event of a heavy downpour or thunderstorm during the afternoon, the main hazards include localized heavy rainfall, which may reduce visibility and gusty winds in downburst-like fashion, up to and in excess of 50 KM/H. Street or flash flooding will be possible in slow-moving showers and thunderstorms. In thunderstorm activity, frequent lightning is also possible.
