The National Emergency Management Organisation (NEMO) is urging residents and motorist in low lying areas, areas prone to flooding, lahar or mudflows and landslide to be vigilant and exercise caution.
A Flash Flood Warning is in effect for St. Vincent and the Grenadines until 12:00 pm on Sunday 15th, August 2021. In this case a Flash-Flood Warning means that flooding is about to occur or already occurring.
According to Meteorological Forecaster, Gregory Cato, the latest model guidance is suggesting rainfall accumulations of approximately 2-3 inches with isolated higher amounts in mountainous areas within the next 12 hours.
The National Emergency Management Organisation (NEMO) urges all residents especially persons living near rivers and streams in areas such as Fitz-Hughes, Chateaubelair, Spring Village, Vermont, Buccament, Rose Place, Calliaqua, Belair, Dauphine, Arnos Vale, Marriaqua, Lowmans, Greggs, South Rivers, Dickson and Langley Park to be vigilant.
Residents in the red and orange volcano hazard zones are also reminded that lahar flows within the river system is also possible. Lahars are dense mixture of ash and water. This usually occurs during heavy rain which creates mudflow that destroys everything in its path as it rushes down the volcano’s slopes faster than a river.
The lahars are very dangerous. Persons who are in the red zone areas are asked to take the necessary precaution and stay away from the rivers.
Flood Advisory has been upgraded to a Flash-flood warning Issued at 5:00 pm, Saturday 14th August 2021
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.
