A weak tropical wave is crossing the islands and a few scattered showers and isolated thunderstorms are likely across St. Vincent and the Grenadines (SVG) tonight. Saharan dust concentrations vary between a thin-film and slight haze across our area. The next tropical wave could be approaching the islands Friday night, with scattered showers and thunderstorms by early Saturday. A few showers could linger across SVG on Sunday…Be alert in areas prone to flash-flooding, or near rivers and streams.
Moderate to fresh (20 – 35 km/h) east north-easterly trades could gust near 40 km/h at times and directions are likely to turn east south-easterly on occasions, as the tropical waves cross our islands.
East north-easterly swells range between 0.5 m and 1.2 m on western coasts with slight sea-conditions and up to 1.8 m on eastern coasts of SVG with slight to moderate sea-conditions. Swell heights could temporarily rise (1.0 m – 1.5 m on west and up to 2.0 m on east) on Friday and start falling during the night; ranging (0.5 m – 1.2 m) on western coasts and near 1.5 m on eastern coasts by Saturday.
