Adverse Weather Alert Discontinued

The Trinidad and Tobago Meteorological Service has discontinued the Adverse Weather Alert (Yellow Level) for Trinidad and Tobago as adverse weather did not materialize. We mentioned this yesterday as strong wind shear continues to keep heavy rainfall east of T&T. Still, isolated showers and thunderstorms are possible this afternoon through Tuesday due to favorable atmospheric conditions across the region, in addition to an approaching Tropical Wave 65.

The Forecast

Monday: Stronger shower and thunderstorm activity is forecast to remain east of T&T. Few isolated showers are possible but not likely overnight. By daybreak, partly cloudy skies are forecast with the odd light to moderate shower. By the late morning (10:00 AM), showers and isolated thunderstorms are forecast, with mostly cloudy intervals through the afternoon. Heavy rainfall will still favor Eastern Trinidad. A break in activity will come by the late afternoon into the night, with brisk showers and light rain still possible. A resurgence of activity is possible near midnight.

For Trinidad and Tobago, the main hazards will be heavy rainfall, mainly across eastern halves of both islands producing flooding, as well as gusty winds up to and in excess of 55 KM/H. Street and flash flooding will be likely on Monday and Tuesday.

While thunderstorm activity is forecast to be brief, due to strong low-level winds, frequent lightning will still be possible as upper-level enhancement may trigger locally severe thunderstorm activity. This means violent rainfall, gusty winds in a downburst-like fashion, up to and in excess of 55 KM/H, and frequent lightning. Landslides are also possible in elevated areas, particularly Monday and Tuesday.
