SVG Met issues a Flash Flood Watch for St.Vincent and The Grenadines 22.08.22
A FLASH-FLOOD WATCH IS IN EFFECT FOR ST VINCENT AND THE
GRENADINES UNTIL 6:00 AM Tuesday, 23rd AUGUST 2022
Issued at 12:00 noon, Monday 22nd August, 2022
An upper level trough is favourably positioned over Saint Vincent and the Grenadines producing rain and thunderstorm activity. The trough will continue to linger across our area into Tuesday morning, and therefore these weather conditions are forecast to persist. Model guidance is indicating 50mm of rainfall by tonight, especially on the Windward side of the island. As a result, the weather advisory that was already in effect for a low risk of flooding for St.Vincent and the Grenadines is now upgraded to a Flash-Flood watch and will remain in effect until 6:00 am, Tuesday 23rd August 2022.
NEMO advises residents and motorists in areas prone to flooding and landslides or near rivers and streams to exercise caution.
A Flood-Watch is issued when conditions are favourable and there exists the possibility of flooding during the watch period.
This flash-flood watch may be upgraded to a warning if conditions warrant.
