Scattered showers this afternoon could intensify overnight/early Thursday with thunderstorm activity across SVG, as mid-upper level moisture enhances a tropical wave crossing the island chain.
The instability could be temporarily decreased during Friday, but a trailing trough could result in scattered showers with isolated thunderstorms by evening to decrease Saturday.
Gentle and occasionally light (less than 20km/h) breeze is expected this afternoon into tonight, mainly from the north-north-east, turning southeasterly by Thursday afternoon and becoming moderate (20 -30 km/h) Friday.
Slight to moderate (1.0 – 1.5m) sea conditions with easterly swells are expected across SVG, gently falling to slight (0.6 to 1.2m) during Thursday, before returning to slight to moderate again Friday
