Instability remains elevated across the islands with moisture pooling ahead of another tropical wave/trough which detached from previous tropical wave. The axis is expected to cross the northern Windward and Leeward Islands late Tuesday. A northward positioning of the Inter-Tropical Convergence Zone (ITCZ) should add equatorial moisture on Wednesday. Following quickly behind, is another tropical wave to bring cloudy skies, showers and possibly thunderstorm activity across the island chain by Wednesday night into Thursday.

Light/gentle southerly breeze should continue into Tuesday, becoming variable at times. Gentle to moderate breeze should be across the islands by Wednesday and backing to north-east by evening.

Sea conditions are slight to moderate in open water with east north-easterly swells ranging 1.0 - 2.0 m across SVG.

Slight (0.5 - 1.2 m) seas are expected by Wednesday with easterly swells.
