Occasional shallow showers under breezy and hazy conditions are likely within the next 24 hours before another tropical wave begins to affect St Vincent & the Grenadines on Wednesday. An increase in cloudiness is likely as the day progresses with pockets of moderate showers and the possibility of isolated thunderstorms. Lingering instability associated with the wave should allow for additional activity on Thursday with showers intensifying across the Grenadines firstly before spreading to the mainland by late afternoon. In addition, Saharan dust concentrations will remain across the islands during the next 72 hours period, reducing visibility and decreasing air quality.
