A tropical wave coupled with the Inter-Tropical Convergence Zone (ITCZ) and a favourable
upper level environment will continue to generate moderate to heavy showers and isolated
thunderstorms across Saint Vincent and the Grenadines tonight into tomorrow. In addition, this
instability will produce wind speeds near 12 – 25 mph (20 – 40km/h) with higher gusts near
showers.
Rainfall accumulations of 75mm (approximately 3 inches) are possible through Tuesday with
isolated higher amounts in mountainous areas.
Thus, a Flash-Flood Watch is in effect for St. Vincent and the Grenadines from 6:00 p.m
today, August 17th 2020 until 12:00 noon Tuesday 18th, 2020.
Residents and motorist in areas prone to flooding and landslides or near rivers and
streams should exercise caution.
A Flood-Watch is issued when conditions are favourable and there exists the possibility of
flooding during the watch period.
This flood watch may be upgraded to a warning if conditions warrant.
