72 Hours Outlook

A relatively moist atmosphere will continue across Saint Vincent and the Grenadines during the next 3 days. Model guidance indicates that this moisture level will be elevated sometime around Tuesday night into Wednesday. In addition, a favourable upper level environment due to the presence of the upper level trough can add to the instability across the island chain and hence, some showers and isolated thunderstorms are likely. By Wednesday night, roughly 1 ½ inch of rainfall is possible to the north of the mainland, and close to 1 inch is likely elsewhere. Residents and motorists in the red and orange zones near La Soufriere volcano should remain alert. This advisory may be upgraded if necessary.
