Flash flood watch 10th November 2020 (12:00 noon)

A Flash-Flood Watch is in effect for St. Vincent and the Grenadines (SVG) until further notice

Issued: 12:00 noon Tuesday, 10th November, 2020

From tonight until Saturday, there is a high chance of occasional showers across SVG, some of which are likely to become moderate to heavy, as an upper level trough interacts with unstable conditions at lower levels.

The atmosphere is moist across the region. Firstly, from an area of disturbance located over the eastern Caribbean Sea that is forecast to turn into a depression later this week as it moves westward. Secondly, from an approaching surface trough , and thirdly from a favourable positioned upper level trough that will become more pronounced as time progress.

Model guidance is indicating a little over 2 inches (50mm) of rainfall during the next 48 hours period for SVG, and due to the already saturated nature of the soil, and current reports of landslides, a flash- flood watch remains in effect until further notice.

 

Residents and motorists should be prepared in areas prone to flooding and landslides or near rivers and streams.

 

A Flood-Watch is issued when conditions are favourable and there exists the possibility of flooding during the watch period, and may be upgraded to a warning if conditions warrant.
