From Tuesday night 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 leveltrough 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
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.
