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.
