Flash-Flood Watch 23rd August 4pm
A FLASH-FLOOD WARNING IS IN EFFECT FOR ST VINCENT AND THE GRENADINES UNTIL 6 AM 24th AUGUST 2021
Issued at 4:00 pm, Monday 23rd August, 2021
Frequent pockets of moderate to heavy showers associated with the passage of a tropical wave will continue to affect Saint Vincent and the Grenadines this evening into tonight. In addition, another tropical wave is approaching the islands and upper levels remain favorable. Rainfall accumulations of 75-100mm (approximately 3-4 inches) are possible during the next 12 hours period.
Due to the already saturated nature of the soils, any additional rainfall could lead to additional flooding and land slippage.
As a result, the Flash- Flood watch that was already in effect has been upgraded to a Flash-Flood warning for St. Vincent and the Grenadines until 6:00 am, Tuesday 24th 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.
In addition, wind speeds ranging between 30 - 50km/h or (19 - 31mph) are anticipated into Tuesday. These near gale speeds has been agitating the ocean surface with swells peaking to 2.5m on the eastern coasts. Small craft operators and sea bathers should exercise extreme caution for above normal sea swells and gusty winds and reduced visibility due to heavy showers.
A Flash-Flood Warning is issued when flooding is imminent or already occurring.
