A relatively moist atmosphere would allow for occasionally cloudy skies and brief sporadic shower activity across St. Vincent & the Grenadines over the next 24hours. There is a chance of showers around Tuesday morning to the northern portion of the island as low-level instability affects the Central Windwards. By late evening, unstable conditions from the south may trigger a few showers as well. Similar conditions are anticipated early Wednesday as weak pulses cross the island chain. A tropical wave is anticipated around Thursday afternoon and should generate cloudy to overcast skies, scattered showers, periods of rain and possible isolated thunderstorms by late evening.
