Generally cloudy skies are expected into Wednesday as moisture trails behind the tropical wave that is to the west of the islands. The possibility exists for scattered showers, occasionally breezy conditions and a low chance of isolated thunderstorms across Saint Vincent and the Grenadines tonight into tomorrow. A southward migration of the ITCZ could bring showers across the Grenadines tomorrow. On Thursday fair to occasionally cloudy conditions are anticipated whereas a shearline associated with an approaching tropical wave could trigger some showers across the islands early Friday. Instability associated with a tropical disturbance just behind the tropical wave should allow for some scattered showers and isolated thunderstorms during the afternoon period although the feature is projected to pass further north of the chain.
Winds will be generally from the east north east tonight, becoming strong(~40 km/h) closer to midnight. Winds would gradually decease across the next two days until they become east south easterly and light(10~20km/h) around Friday afternoon.
Sea conditions are currently moderate in open waters with swells peaking to 1.5m on the western coasts and 2.5m on the eastern coasts. Small craft operators and sea bathers should exercise caution for above normal sea swells and gusty winds. General slight sea conditions (1.0-1.2m) are likely to return around Thursday.
Slight intrusion should become visible on Wednesday but could thin out by the end of the week.
