Over the next 3 days, the atmosphere will remain relatively moist as a tropical wave exits the region, and a trough system moves into the area. There is a possibility that moisture levels can fluctuate as Friday progresses into Saturday, reducing the chance of showers, but due to the approaching deep layered trough, residents and motorists are asked to be alert.
The trough should begin to affect sometime around Sunday. Model guidance is indicating 20 mm-50 mm of rainfall accumulation lingering to the east of SVG by Sunday night.
Friday: A few light to moderate scattered showers are forecast throughout the day and in the night.
Saturday: Fair to occasionally cloudy skies with a high chance of some scattered showers and slight isolated thunderstorms as the trough draws closer.
Sunday: Some fair to occasionally cloudy skies is possible with a high chance of showers and isolated thunderstorm activity as the day progresses as the trough system influences the weather pattern.
Winds will become generally from the east north east (ENE) at 20km/h - 30 km/h. Seas are forecast to be slight to moderate in open waters with swells peaking at 1.0m on the western coasts and 2.0m on the eastern coasts. In addition, there should be no significant haze intrusion within this forecast period.
