A FLASH-FLOOD WATCH is in effect for St. Vincent and the Grenadines

Issued: 12:00 pm Sunday, 27th September, 2020 

Moderate to heavy showers, intermittent rain and scattered thunderstorms are anticipated across Saint Vincent and the Grenadines due to the passage of a tropical wave currently affecting the Windward Islands. Rainfall accumulations of 50 – 75mm (approximately 2-3 inches) with isolated higher amounts in mountainous areas are possible during the next 12-18 hours. In addition, this wave will generate wind speeds between 6 – 16 mph (10 – 25km/h) with higher gusts near showers. 

As a result, the weather advisory which is in effect for St. Vincent & the Grenadines has been upgraded to a flash-flood watch and will remain in effect until 6:00 am Monday 28th, September 2020. 

Residents and motorists in areas prone to flooding and landslides or near rivers and streams should continue to exercise 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.
