A Flood Watch means that the conditions are favourable and there exists the possibility of some flooding within the Watch area, in this case, within the next 24 hours.
An approaching tropical wave located just east of the island chain is expected to generate moderate to heavy showers, periods of rain, thunderstorms and occasional gusty winds across Saint Vincent and the Grenadines from late tonight, with a likely increase in intensity by early tomorrow morning.
As a result, a Flood-Watch is now in effect for St. Vincent and the Grenadines, and will remain in effect until 6:00 pm Saturday 18th August 2018.
Current model data is suggesting rainfall accumulations of 100 mm to 150 mm (4 inches to 6 inches) during the watch period.
Residents and motorists in flood-prone areas, areas prone to land slippage, near rivers and streams should exercise caution and remain alert.
This flood-watch may be upgraded to a flood-warning if conditions warrant.
The Barbados Meteorological Services and St Vincent and the Grenadines Meteorological Services will continue to monitor this system and provide the necessary updates.
