Moisture from a tropical wave is being enhanced by an upper level trough resulting in moderate to heavy showers with isolated thunderstorms across Saint Vincent and the Grenadines. This activity will continue into tonight, with a few showers anticipated in the morning.

Varying concentrations of Saharan dust haze would be visible across St. Vincent & the Grenadines over the next few days. In addition, breezy conditions would persist.  A few showers are anticipated into Saturday along with occasionally cloudy skies as a wave approaches the islands by nightfall. Moderate showers are expected across the islands from Saturday night into early Sunday especially across the southern Grenadines. Conditions should improve by early Sunday afternoon.

Today, a tropical wave triggered some moderate to heavy showers and isolated thunderstorms across St. Vincent & the Grenadines. Similar conditions are anticipated tonight into Friday morning as the feature progresses westward. Therefore, residents and motorists in areas prone to flooding and landslides or near rivers and streams are asked to remain alert. Saturday is forecast to be occasionally cloudy and breezy with scattered showers. Apart from some early morning showers on Sunday, fair to partly cloudy and warm conditions should persist.

A tropical wave will begin to affect the island chain tonight, resulting in a few scattered showers. This wave will continue to affect the islands on Thursday. Model guidance is indicating some moderate showers around Thursday night into Friday. Saturday is forecast to be occasionally cloudy and breezy with scattered showers.

Unstable conditions may trigger some occasional showers by nightfall and into the early hours of Wednesday. A tropical wave should begin to interact with the island chain by Wednesday evening with light to moderate showers quite likely heading into Thursday. There is also a slight chance for isolated thunderstorms by mid-afternoon Thursday as this feature affects the islands. Instability trailing the wave would allow for similar conditions on Friday.

The light wind regime continues, resulting in humid conditions across St. Vincent & the Grenadines tonight. A few light isolated showers are anticipated by mid-morning Tuesday while unstable conditions may trigger some occasional moderate showers by nightfall and into the early hours of Wednesday. A topical wave should begin to interact with the island chain by Wednesday evening with light to moderate showers quite likely heading into Thursday. There is also a slight chance for isolated thunderstorms by mid-afternoon Thursday as this feature affects the islands.

A fluctuation in moisture level will result in intermittent showers across Saint Vincent and the Grenadines during the next 48 hours.

The most significant shower activity is forecast from around Wednesday afternoon. Model guidance is indicating moderate showers across the Grenadine Islands around this time, spreading to the mainland by evening.

Humid conditions and localised activity should persist into tomorrow as a south easterly light wind regime continues. Although fair conditions are anticipated early Sunday, a northward migration of the ITCZ coupled with interaction from a tropical wave could generate occasionally cloudy skies and trigger a few scattered showers over the Grenadines during mid afternoon. These conditions could extend to the mainland by nightfall into Monday with a low chance of isolated thunderstorms.

A few isolated showers are forecast across St. Vincent & the Grenadines tonight into tomorrow morning. Humid conditions are anticipated across Saturday as a south easterly light wind regime persists. In addition, a tropical wave edges closer to the islands by mid afternoon and could trigger some scattered showers in the process. Mostly fair conditions are anticipated early Sunday, however a northward migration of the ITCZ coupled with interaction from the aforementioned tropical wave should generate some cloudy conditions with light to moderate scattered showers over the Grenadines during the afternoon. These conditions could extend to the mainland by nightfall into Monday with a low chance of isolated thunderstorms.

Occasional showers are forecast across Saint Vincent and the Grenadines tonight, with the chance of showers increasing tomorrow morning as a weak trough move across the island chain. Model guidance is indicating the possibility of isolated thunderstorms. After which, mostly fair conditions are forecast into Saturday before a tropical wave begins to affect SVG sometime around Saturday afternoon. Moderate showers and isolated thunderstorms are possible mainly across the Grenadine Islands. Sunday is forecast to be mostly fair.
