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.
Gentle and seldom moderate (15km/h – 25km/h) east to east south easterly (E-ESE) trades will move across Saint Vincent and the Grenadines over the next 24 hours. The light wind regime should persist until a slight increase(near 30km/h) around Wednesday. The flow would become east north easterly on Thursday ahead of the anticipated tropical wave. Slight sea conditions, with swells peaking to 0.5m on the western coasts and 1.2m on the eastern coasts are forecast across the chain over the next 72 hours.
Saharan dust intrusion with varying concentrations will continue to affect SVG with some slight improvement around Wednesday afternoon.
