Adverse Weather Alert Discontinued, Isolated T-Storms Possible Overnight

Adverse Weather Alert Discontinued

The Trinidad and Tobago Meteorological Service has discontinued the Adverse Weather Alert (Yellow Level) for Trinidad. However, we are monitoring showers and thunderstorms developing along the northern coast of Venezuela, south of Trinidad which could move across the island into tomorrow. However, most of the thunderstorm activity will remain out in the Gulf of Paria.

Information from the Trinidad and Tobago Meteorological Service concerning the Adverse Weather Alert Discontinuation for September 11th, 2020.

According to the TTMS, “Severe weather activity has subsided. The remainder of the afternoon and evening is expected to remain settled.”

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.

Models show an increase in shower and thunderstorm activity after nightfall, but this depends on if convection can develop along the Northern coast of Venezuela and drift northward. If this occurs, the heavier activity will favor Southern and Southwestern Trinidad, with hazardous marine conditions in the Gulf of Paria.

Low-level winds are forecast to be from the south to southeast at 10 knots initially. These winds may become south to southwesterly overnight Friday into Saturday. In sheltered areas, waves are forecast to be near calm to below 1.0 meter and choppy at times. Long period swells (generally between 10-12 seconds) will produce larger than usual waves in nearshore areas of northern and eastern coasts of T&T through Sunday.

Note: Overnight Friday into Saturday, strong winds and agitated seas are possible in the Gulf of Paria. Particularly along the Northwestern coasts, waves near 1 meter are possible. Particularly if strong thunderstorms persist across the Gulf of Paria as it moves north.

Hazards: The main hazards include heavy rainfall, which may reduce visibility and gusty winds 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. Gusty winds may cause power dips/outages, downed trees, and localized wind damage.
