St. Vincent and the Grenadines is expected to experience unstable weather conditions over the next 72 hours, as a trough system brings periods of showers and isolated thunderstorms. According to the latest forecast from the SVG Meteorological Services, residents should prepare for fluctuating weather beginning this weekend.
On Sunday, September 15th, the day will start off partly cloudy and warm, but conditions are expected to deteriorate by the evening with the possibility of isolated thunderstorms. The seas will remain smooth to moderate, with wave heights between 0.5m to 1.5m, making marine conditions relatively stable.
The most significant weather changes will occur on Monday, September 16th, when a trough system could trigger more widespread showers and isolated thunderstorms. The weather office is advising residents, especially those in flood-prone areas or near rivers and streams, to remain alert for potential flooding or landslides. Seas will continue to remain moderate, with no marine advisories issued at this time, but boaters should stay cautious.
By Tuesday, September 17th, while conditions may still be cloudy with scattered showers, the likelihood of thunderstorms will decrease. Skies are forecast to clear by the end of the day, with periods of occasional fair weather returning.
As winds are expected to be light to moderate (15-25 km/h) from the east-southeast, occasional gusts near showers may occur. Additionally, a film of Saharan dust is predicted to linger into early Sunday, gradually thinning out as the day progresses.
Residents are encouraged to remain vigilant, particularly in vulnerable areas, as the forecast indicates the potential for moderate showers and changing weather patterns over the weekend and into Monday.
