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.
Gentle to moderate (15-25km/h) east north easterly (ENE) trades could become east south easterly by Saturday afternoon. Winds speeds should increase(near 30km/h) and revert to east north easterly by late Sunday, before further increasing(near 45km/h) on Monday.
Seas will remain slight to moderate in open waters, with easterly swells peaking at 1.0m on western coasts and between 1.5m – 2.0m on eastern coasts within the next 48 hours. A deterioration relative to these conditions is likely from late Sunday into Monday as wind speeds increase. Small craft operators and sea bathers should exercise caution for reduced visibility/air-quality due to Saharan dust haze
