Vincentians have been advised to pay attention to weather reports for the island.
This as the St Vincent and the Grenadines Meteorological Service continues to monitor the progress of a strong tropical wave approximately 900 miles east- southeast of SVG.
It says the wave is presently moving westward to west-northwest around 15 miles per hour and producing disorganised showers and thunderstorms.
The Met Office says some development of this disturbance will be possible during the next couple of days before upper-level winds become less conducive for further organisation by Thursday.
It says regardless of the development, activity head of the wave should begin to affect the islands by late Wednesday with moderate to heavy showers accompanied by thunderstorms and gusty winds.
Due to expected rainfall accumulations and the saturated nature of the soils from recent rainfall events, flash flood watches or warnings may be issued during the upcoming days for SVG.
