The Barbados Meteorological Services (BMS) has upgraded the flash-flood watch to a flash-flood warning for the island.

According to the BMS, surface to low-level troughing supported by upper-level atmospheric conditions is expected to generate moderate to intense showers as well as periods of sustained rain throughout Tuesday night.

With soils across the island already heavily saturated, an additional one to two inches of rainfall is forecast to trigger new flooding and worsen existing water accumulation.

Potential impacts include rapid runoff from higher elevations, soil erosion, land slippage on exposed terrain, water pooling on roads and open fields, and rising water levels in ponds and other natural basins.

The BMS also warned that debris carried from elevated areas could flow rapidly through waterways, creating hazards for both motorists and residents. Some roads, including those near hillsides and coastal corridors, may become impassable, leading to delays or limited access to smaller towns.

A flash-flood warning is issued when heavy or excessive rainfall is either occurring or imminent, typically within a six-hour period.

The public is strongly advised to stay alert and monitor weather updates from the BMS.

This warning will remain in effect until 6 a.m. on Wednesday, December 3, or may be updated earlier if conditions change. (BMS)
