A layer of Saharan dust encompasses a tropical wave approaching the Eastern Caribbean. While the majority of the showers associated with this wave is concentrated mostly to the south, dust interaction may limit the intensity. Nevertheless, instability ahead of this wave could still trigger some moderate showers early Saturday morning. Models are further suggesting a cessation in shower activity during Saturday, but by nightfall, and into early Sunday morning, some light to moderate showers with low chance of isolated thunderstorms are likely across St. Vincent & the Grenadines. Partly cloudy skies with some scattered showers are likely on Monday as patches of moisture trails the wave. Pleasant(fair) conditions should return by mid afternoon Monday.
Moderate to occasionally strong (~25 - 40km/h) east north easterly trades will move across the islands over the next 12 hours. The flow will become fresh (~35km/h) and east south easterly(ESE) by late Saturday after the passage of the wave's axis. Occasionally strong(~40km/h) trades may return on Sunday before slightly decreasing on Monday again.
Moderate sea conditions with swells peaking to 1.5m on the western coasts and 2.0m on the eastern coasts are forecast during the next 24 hours. Small craft operators and sea bathers should exercise caution for above normal sea swells especially on eastern coasts. A return to slight to moderate(1.0m - 1.5m) conditions are likely on Monday.
Varying concentrations of Saharan dust haze will continue to cross the island chain over the next 72 hours. Residents should continue exercise caution for reduced visibility and poor air quality.
