Residents, motorists, and mariners across St. Vincent and the Grenadines are advised to maintain vigilance as atmospheric instability, heavy rainfall risks, Saharan dust haze, and marine hazards affect the islands from Sunday, September 13, 2026, through early next week.
A surface trough supported by favorable upper-level atmospheric conditions will continue to bring mostly cloudy and hazy weather with showers and thunderstorms across the islands on Sunday. The St. Vincent and the Grenadines Meteorological Services has issued a weather advisory urging residents and motorists in areas prone to flash flooding and landslides, as well as those living near rivers and streams, to remain on alert.
Concurrently, a thick blanket of Saharan dust continues to impact the area, significantly reducing air quality and visibility. Although dust levels are forecast to show brief improvement late Sunday, residents are advised to continue taking necessary health and safety precautions.
Atmospheric instability will linger into Monday, September 14, maintaining occasionally cloudy conditions with ongoing showers ahead of an approaching tropical wave. While the explicit flash-flood alert eases after Sunday, the advisory to take precautions regarding Saharan haze and reduced visibility remains active.
Looking further ahead, the temporary relief from atmospheric dust will be short-lived, as another plume of Saharan dust is projected to arrive on Tuesday.
