Instability trailing a tropical wave would continue to generate cloudy skies and trigger moderate showers and isolated thunderstorms across SVG tonight. A flash flood watch remains in effect. Residents and motorists in areas prone to flash-flooding and landslides or near rivers and streams should be prepared. Lingering moisture would still allow for cloudy skies on Friday however, the chance of showers decreases as the day progresses. As a weak ridge pattern rebuilds, additional improvement to the weather conditions are anticipated across the weekend. Model guidance suggests however, that the Grenadine islands to the extreme south could still experience occasional showers as patches of moisture linger.
Moderate to fresh(20-30km/h) east south easterly trades will cross the islands during Thursday night becoming easterly to east north easterly from Friday. Gusts may accompany showers during Thursday night. Seas are moderate in open water with swells peaking near 1.5m on western coasts and up to 2.5m on eastern coasts. Small craft operators and sea bathers should exercise caution for occasional gusty winds and above normal sea swells. Seas could improve late Friday. In addition, Saharan dust concentrations could begin to thin out around Saturday evening.
