Tropical Wave To Affect SVG: Scattered Showers, Isolated Thunderstorms Forecast

The SVG met service said a tropical wave is affecting the extreme  Southern Windwards Islands. With this weather system, St Vincent can expect, scattered showers and isolated thunderstorms.

In its outlook, the met service said the Inter-Tropical Convergence Zone (ITCZ) is positioned near 10o N and upper level conditions are favouring cloud build-ups with showers and thunderstorm activity across that latitude.

Additionally, a tropical wave is affecting the extreme southern Windward Islands today. However, a layer of dry air is hindering shower activity within the northern portion of the wave environment.

SVG met stated that the southernmost Grenadine Islands, as well as Grenada, are experiencing abundant moisture as upper-level conditions support scattered moderate convection and isolated thunderstorms, with periods of rain to continue this afternoon.

Instability and moisture could spread northward reaching mainland Saint Vincent by evening. As instability lingers, moisture at the mid-levels is expected to enhance shower activity into Thursday morning, with showers decreasing by afternoon.
