FLASH-FLOOD WATCH IS IN EFFECT FOR SVG

Issued at 6:00 am, Sunday 29th November, 2020

Occasional moderate to heavy showers and isolated thunderstorms are anticipated across Saint Vincent and the Grenadines due to the passage of a surface to low-level trough. Rainfall accumulations of 50-75mm (approximately 2-3 inches) with isolated higher amounts in mountainous areas are possible during the next 6 hours.

During the last 12 hours, rainfall accumulations of over 4 inches (~100 mm) have been recorded by some stations as well as increase in the water levels across the mainland. Due to the saturated nature of the soils, any additional rainfall could lead to additional flooding and land slippage.

As a result, the flood advisory that was already in effect has been upgraded to a Flash-Flood watch for St. Vincent and the Grenadines until 12 noon today. Residents and motorists in areas prone to flooding and landslides or near rivers and streams should exercise extreme caution.

A Flood-Watch is issued when conditions are favourable and there exists the possibility of flooding during the watch period.

This flash-flood watch may be upgraded to a warning if conditions warrant.
