Moisture trailing a tropical wave is expected to cross our islands overnight into early morning. Light to moderate rain and pockets of moderate/heavy showers with thunderstorm activity are likely across St. Vincent and the Grenadines (SVG) tonight into early Thursday…Be alert in areas prone to flash-flooding, or near rivers and streams. Moderate haze is likely across our area late Thursday, due to patches of Saharan dust. Thereafter, there is a high chance that a Tropical Storm (T.S) could be approaching the island chain by Friday. POTENTIAL T.S center located near 9.6N 43.7W at 5pm today. Showers and winds could increase across SVG by Friday morning, increasing during the afternoon/evening and shower
activity could linger during Saturday. A TROPICAL STORM WATCH is in effect for St. Vincent and the Grenadines.
Moderate to fresh (25 – 35 km/h) easterly breeze could increase occasionally near 45 km/h tonight and turn east south-easterly. North-easterly trades are expected late Thursday, becoming northerly during Friday with steady increase as the Potential T.S crosses the islands. A southerly wind-flow is likely during Friday night and Saturday. Light breeze from the east is possible by Saturday evening.
East north-easterly swells range between 1.2 m to 1.8 m on western coasts with slight to moderate sea-conditions and up to 2.5 m on eastern coasts of SVG, with moderate sea-conditions based on increased wind speeds…Small-craft operators and sea-bathers should exercise caution for above normal sea-swells and occasional gusty winds. Temporary fall in swell heights may be noticeable late Thursday, but steady rise is expected Friday. Mariners should be aware that rough/very rough (nearing 5.0 m) swells with storm conditions are likely as the Potential T.S crosses the islands. Swell heights are expected to fall during Saturday, becoming slight to moderate (0.5 m – 1.5 m) by evening.
