St. Vincent and the Grenadines is once again under heightened weather alert as a tropical wave makes its way across the Eastern Caribbean, triggering a Flash Flood Watch for the entire country. This watch, issued by the St. Vincent and the Grenadines Meteorological Services, comes after significant rainfall was recorded across the islands and anticipates worsening weather over the next 12 to 36 hours.
According to Meteorologist Gregory Cato, the wave is bringing an influx of moisture-laden clouds, which are expected to produce showers of varying intensities, ranging from light drizzle to intense downpours. Residents can also expect periods of persistent light rain interspersed with isolated thunderstorms, particularly during the late evening into Wednesday.
At the Argyle International Airport, over 25 mm (1 inch) of rain has already been measured within the last 24 hours — a figure likely to climb significantly as the system progresses. Forecast models suggest that rainfall accumulations between 50 and 100 mm (2 to 4 inches) are possible across the country, with higher localized amounts anticipated in elevated or mountainous areas such as the interior of mainland St. Vincent.
The Flash Flood Watch, which upgrades the previous low-risk weather advisory, signals that flooding is possible in vulnerable areas — particularly low-lying zones, coastal communities, riverbanks, and regions prone to landslides.

Impacts & Hazards
Flash flooding in valleys and urban areas with poor drainage
Landslides in hilly or unstable terrains, especially in rural districts
Reduced visibility and slick road conditions, increasing the risk of traffic accidents
Rising river levels and rapidly overflowing streams
Residents in areas such as Vermont, Buccament, Mesopotamia, Sandy Bay, and Marriaqua should remain especially vigilant, as these communities have historically experienced rapid-onset flooding and landslide events during prolonged rainfall.

Next Steps
The Flash Flood Watch will remain in effect until further notice, and may be upgraded to a Flash Flood Warning if conditions deteriorate further or rainfall thresholds are met.
As the hurricane season continues to ramp up, this event is a reminder of the importance of early preparation and community vigilance. The Meteorological Services will continue to monitor the system and provide timely updates.
