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.
