A depression in the Atlantic is causing the pressure gradient to weaken, allowing for light wind speeds across our area. In addition, an east south easterly wind flow would transfer equatorial moisture to our islands.
Consequently, warm conditions are expected over the next few days although afternoons may be interrupted by localised shower activity accompanied by isolated thunderstorms. Residents and motorists in areas prone to flooding and landslides or near rivers and streams should remain alert.
Gentle(10-15km/h) east to east south easterly trades would cross the islands over the next few days, decreasing(<10km/h) further on Tuesday.
A slight increase(15-20km/h) is expected for Wednesday. Seas are slight on western coasts peaking up to 1.0 m and moderate on eastern coasts peaking up to 1.5 m. Seas are expected to become slight(0.5m – 1.2m) from tonight as the light wind regime continues. Varying Saharan dust concentrations will traverse our area over the next 3 days.

A tropical depression is in the Mid-Atlantic and by this afternoon, will likely turn into a tropical storm. This storm is forecast to remain over open waters away from the Lesser Antilles, and will not be directly impacting SVG.
However, due to the presence of this storm in the Atlantic, the wind speeds across Saint Vincent and the Grenadines will be affected, decreasing to 15km/h-25km/h around Sunday and Monday.
In addition, moisture will gradually build up from the south as the storm makes its northward progression over the Central Atlantic Ocean. This light wind regime and the gradual build up of moisture will likely result in unstable conditions across the island chain.
Therefore, from this afternoon a few shallow scattered showers are forecast, becoming more frequent on Sunday with the possibility of isolated thunderstorms around Sunday afternoon. Similar conditions are forecast for Monday.
Seas will be slight to moderate in open waters, with swells ranging between 0.5m- 1.0m on the western coasts, and 1.5m-2.0m on the eastern coasts. Haze is forecast to thin out from tonight, with no significant intrusion expected on Monday.
