As an east- north easterly to easterly wind flow associated with the Atlantic high pressure system continues to bring shallow moisture across the islands, occasional cloudiness and a few brief showers may be generated tonight over a few areas in Saint Vincent and the Grenadines.
Furthermore, by tomorrow, the Atlantic high pressure system will regain full dominance across the region and some occasional showers are likely throughout the day.
Weak instability can be seen approaching from the north east around Wednesday night and by Thursday the dominance of the Atlantic high pressure system will be weaken by a weak surface trough. Cloudy periods are therefore likely from Thursday evening and by Friday the weak low level trough will be in control of the weather across the island chain. Model guidance is indicating some scattered showers throughout Friday.
Seas are to remain slight to moderate in open waters with swells peaking to 2.0m. In addition, model guidance is indicating haze intrusion from tomorrow afternoon reducing visibility.
