Thursday: Cloudy skies, hazy conditions and showers are forecast to continue across the Grenadines.

Friday: Generally cloudy with showers and chance of isolated thunderstorms as that fresh south easterly wind flow continues, coupled with a tropical wave being in the vicinity.
Saturday & Sunday: Scattered showers, possibly increasing around the nighttime, as the tropical wave continues to affect the islands.
Winds will blow generally from the south backing to east on occasions at 20km/h - 35km/h, with higher gusts. A decrease in wind speeds is anticipated around Saturday to about 15km/h - 30km/h. Seas are forecast to be moderate in open waters, with swells peaking at 1.5m on the western coasts and peaking at 2.5m on the eastern coasts. Small craft operators and sea bathers are asked to exercise caution. Slight improvement is expected on Saturday (0.5m on the western coasts and 2.0m on the eastern coasts).
