Feeder bands associated with Tropical Storm Grace which is presently affecting the Northern Leeward islands is  affecting the Windward Islands. As a result, occasional light to moderate shower activity which have  started across Saint Vincent and the Grenadines (SVG) this afternoon, is likely to intensify tonight with heavy  showers, thunderstorms and gusty winds. 

Latest model guidance is suggesting rainfall accumulations of 50-75mm (approximately 2-3 inches) with isolated  higher amounts in mountainous areas within the next 12 hours. Therefore, the potential for flash-flooding is  elevated. 

Consequently, the Flash Flood Advisory for a low risk of flooding which is already in effect for St. Vincent and  the Grenadines, has now been upgraded to a Flash-Flood Warning until 12:00 pm Sunday 15th, August 2021. 

Residents and motorists in areas prone to flooding and landslides or near rivers and streams should take  the necessary precautionary measures to protect life and property. 

A Flash-Flood Warning in this case means that flooding is imminent or already occurring.
