Event description

A tropical wave continues to affect Saint Vincent and the Grenadines. Cloudy to overcast skies, pockets of moderate to heavy showers, periods of light rain and thunderstorms will persist across Saint Vincent and the Grenadines. Model guidance suggests rainfall accumulations of 75 mm to 100 mm (approximately 3–4 inches), with isolated higher amounts in mountainous areas possible within the upcoming days. During the last six hours, close to 2 inches (50 mm) of rainfall has been recorded at the Argyle International Airport, with moderate to heavy showers ongoing. There have also been reports of rivers overflowing their banks in communities across SVG. Therefore, the weather advisory previously in effect for a low risk of flooding has been upgraded to a Flash-Flood Watch for Saint Vincent and the Grenadines.

Instructions

Residents and motorists in areas prone to flooding and landslides or near rivers and streams should exercise extreme caution and continue to monitor official weather. Flooding expected in Arnos Vale (ET Joshua center, Sunrise supermarket) .
