Residents across St. Vincent and the Grenadines are being urged to prepare for possible flash flooding, strong winds and dangerous sea conditions as a vigorous tropical wave approaches the country.

The St. Vincent and the Grenadines Meteorological Services issued a Flash Flood Watch at 6 p.m. on Friday, August 14, warning that unsettled weather is expected to affect the country through Saturday.

Forecasters say cloudy to overcast skies, periods of light to heavy showers, rain, gusty winds and scattered thunderstorms are likely over the next 18 to 20 hours. Rainfall totals of 50 to 75 millimetres (around two to three inches) are forecast, with isolated higher amounts possible in mountainous areas.

The Flash Flood Watch will remain in effect until 2 p.m. on Saturday, August 15.

Residents and motorists, particularly those living in flood-prone communities or near rivers and streams, are being advised to remain alert and take the necessary precautions. Areas susceptible to landslides are also at increased risk if heavy rainfall develops.

A High Wind Advisory also remains in effect until 6 p.m. on Saturday. The Meteorological Services warned that higher elevations could experience stronger winds than lower-lying areas. Residents are urged to secure loose outdoor items and stay vigilant for falling tree limbs and damaged overhead utility lines.

Marine conditions are also expected to remain hazardous. A Small Craft Advisory has been extended until 6 p.m. on Saturday, with sustained winds of 37 to 46 km/h (23 to 29 mph) and sea swells of 2.5 to 3 metres (8 to 10 feet) continuing to affect local waters.

Large waves and dangerous rip currents are expected to create unsafe conditions for small vessels, especially along the northern and eastern coastlines. Conditions may deteriorate further during periods of high tide.

The Meteorological Services is advising that only vessels capable of safely operating in these sea conditions should venture out, while sea bathers are urged to stay out of the water until conditions improve.

Images from weather monitoring show the approaching tropical wave, reduced visibility south of mainland St. Vincent and choppy seas, underscoring the deteriorating conditions expected across the islands.

A Flash Flood Watch means conditions are favourable for flash flooding to develop. Residents are encouraged to monitor official forecasts and advisories and be prepared to act should warnings become necessary.
