Occasional isolated showers are likely across SVG within the next 48 hours as shallow cloud patches cross the islands. Saharan dust concentrations would continue to vary and eventually intensify by the beginning of the week. This intrusion of dry air would affect both visibility and air quality and also seek to inhibit shower activity in the process. The Atlantic high pressure system is expected to be dominant until around Sunday evening. An increase in cloud cover is anticipated along with moderate scattered showers into Monday as a tropical wave interacts with the island chain.
