Tonight, occasional cloudy skies, scattered showers and the possibility of isolated thunderstorms exists across SVG. A few isolated showers are likely during the early parts of Thursday. Meanwhile, an approaching tropical wave should begin to affect the islands by nightfall with an upper level trough expected to provide support to this wave. This trough increases the chance of moderate to heavy showers and thunderstorm activity across our islands. Instability trailing the wave could generate showers into the weekend as favourable upper level conditions are expected to continue and this could aid in rapid cloud development. The SVG Meteorological Service will continue to monitor and provide the necessary updates.
Moderate to fresh(25-35km/h) east north easterly trades will cross the islands tonight, becoming easterly and decreasing(20-30km/h) during Thursday. Wind speeds will increase again to strong(25-40km/h) on Friday before decreasing(20-30km/h) again on Saturday.
Seas will generally be slight to moderate in open waters with swells peaking up to 1.0m on the western coasts and ranging between 2.0m-2.5m on the eastern coasts. Small craft operators and sea-bathers should continue to exercise caution for above normal sea swells and occasional gusty winds. In addition, varying concentrations of Saharan dust haze will be visible across the islands gradually thinning out around Saturday.
