Tonight, unstable conditions will be affecting the islands as a shearline pushes from the northwest over the Southern Windward Islands. An increase in cloud cover and showers are likely as the night progress into Friday morning across Saint Vincent and the Grenadines. A dry mid-level is likely to suppress shower activity during Friday.

Model guidance is indicating that by Saturday morning, further instability is likely to result in scattered showers with a slight chance of isolated thunderstorms across Saint Vincent and the Grenadines. Sunday is forecast to be mostly fair.

A light to gentle (10km/h- 20km/h) north easterly wind flow, becoming moderate (25km/h) on occasions will persist across Saint Vincent and the Grenadines. Sea conditions will be slight to moderate in open water (1.0m -1.5m) becoming generally slight (0.5m-1.2m) on Sunday. There will be no significant haze intrusion within this forecast period.
