Flash Flood Watch - 14th August 2026 (6 pm)
A FLASH-FLOOD WATCH is in effect for ST. VINCENT AND THE GRENADINES
Issued at 6:00 pm, Friday 14th August, 2026
Cloudy to overcast skies, light to heavy showers, periods of rain, gusty winds and scattered thunderstorms are anticipated across SVG tonight into Saturday as a strong tropical wave approaches our islands. Current model guidance suggests rainfall accumulations of 50mm-75mm (approximately 2-3 inches) with isolated higher amounts in mountainous areas are possible within the next 18-20 hours. As a result a Flash-Flood watch is now in effect for St. Vincent and the Grenadines and will remain in effect until 2:00 pm tomorrow Saturday 15th August 2026. Residents and motorists in areas prone to flash-flooding and landslides or near rivers and streams should be prepared.
A Flood-Watch is issued when conditions are favorable and there exists the possibility of flooding during the watch period.
This flash-flood watch may be upgraded to a warning if conditions warrant.
A high wind advisory remains in effect for SVG and will be extended until 6pm Saturday 15th August 2026. Residents are strongly urged to be vigilant against falling trees limbs, loose outdoor objects and disconnected over-head wires.
A Small-Craft Advisory also remains in effect for SVG and will be extended until 6pm Saturday 15th August 2026. Sustained winds of 37 to 46 km/h (23 to 29 mph) and sea swells of 2.5 to 3.0 meters (8 to 10 feet) continues to affect the marine area. Large waves and dangerous rip-currents will create unsafe conditions for small-craft operators, particularly on the northern and eastern coastlines. These conditions may become even more adverse during times of high tide. Therefore, only vessels capable of withstanding swells of these magnitudes should venture out. Sea-bathers are also advised to stay out of the water.
Upcoming High-tide times:
Friday 07:03 pm

Small Craft & High Wind Advisory - 13th August 2026 (6 pm)
DUST HAZE, HIGH WIND AND SMALL CRAFT ADVISORIES ARE IN EFFECT FOR ST VINCENT AND THE GRENADINES
Issued at 6:00 pm, Thursday 13th August, 2026
An increase in winds speeds between 35 to 50 km/h (19 to 27 mph) will result in a deterioration of sea conditions. These brisk wind speeds will generate north-easterly swells ranging from 2.5 to 3.0 meters (8 to 10 feet). As a result, a High-Wind and Small-craft Advisory will be in effect for St. Vincent and the Grenadines and its coastal waters from today 6:00 p.m., Thursday, 13th August, 2026 until 9:00 am Saturday August, 2026.
A High-Wind Advisory is issued when sustained winds of 47 to 61 km/h (29 to 38 mph),not associated with a tropical cyclone, are forecast to affect the land area. Residents are strongly urged to be vigilant against falling trees limbs, loose outdoor objects and disconnected over-head wires.
A Small-Craft Advisory is issued when sustained winds of 37 to 46 km/h (23 to 29 mph) and/or sea swells of 2.5 to 3.0 meters (8 to 10 feet) are affecting or forecast to affect the marine area. Large waves and dangerous rip-currents will create unsafe conditions for small-craft operators, particularly on the northern and eastern coastlines. These conditions may become even more adverse during times of high tide. Therefore, only vessels capable of withstanding these swells should venture out. Sea-bathers are also advised to stay out of the water.
Upcoming High-tide times: Thursday 05:55 pm (ongoing)
Friday 07:49 am and 07:03 pm
Saturday 08:40 am
These advisories will be discontinued at 9:00 am Saturday 15th August 2026 or sooner if conditions improve. It may also be extended if conditions warrant.
In addition, moderate-thick Saharan dust haze will continue to cross our islands along Friday, affecting air quality and visibility. Therefore, the dust advisory remains in effect for SVG. Residents should continue to take the necessary precautions for poor air quality and reduced visibility due to Saharan dust-haze. Marine users should also exercise extreme caution due to reduced visibility in dust haze.
