FLASH-FLOOD WATCH IS IN EFFECT FOR ST VINCENT AND THE
GRENADINES

LIssued at 6:00 pm, Monday 26th June, 2023
Instability ahead of an approaching tropical wave will continue to generate occasional
showers over some areas of Saint Vincent and the Grenadines (SVG). However, as the
night progresses, the upper atmosphere is predicted to gradually become favourable,
thus increasing the frequency and intensity of shower/thunderstorm activity. As a result,
the forecast into tomorrow is for cloudy to overcast skies, pockets of moderate to heavy
showers, occasionally gusty winds and isolated thunderstorms. Similar conditions are
likely during Wednesday as instability trailing the tropical wave persist.
The latest forecast model guidance suggests rainfall accumulations of 50-75 millimeters
(approximately 2-3 inches) with isolated higher amounts in mountainous areas. Due to
the saturated nature of the soils following the passage of Tropical Storm Bret, there is a
high probability of flash-flooding and landslides occurring during the watch period.
Consequently, a Flash-Flood Watch is now in effect for St. Vincent and the Grenadines
until 6 pm, Wednesday 28th June, 2023. Residents and motorists in areas prone to
flooding and landslides or near rivers and streams should be prepared.
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.
