The Inter-Tropical Convergence Zone (ITCZ) is resulting in weak unstable conditions with scattered showers and isolated thunderstorms across the Grenadine Islands. Instability should spread across St.Vincent and the Grenadines (SVG) tonight and during Friday, temporarily decreasing Saturday afternoon until early Sunday, when a tropical wave approaches the area.
Moderate (20 - 30km/h) east north-easterly breeze should decrease to gentle tonight and light early Friday,
while turning east south-easterly. North- easterly moderate breeze is expected during Sunday with the approach of a tropical wave.
Slight to moderate (1.0 to 2.0m) sea conditions with north-easterly swells are across SVG. While slight seas are expected on west coasts, moderate swells on east coasts should gradually fall, peaking near 1.5m during Friday and further to 1.2m Sunday afternoon.
