A surface to mid-level trough will continue to affect Saint Vincent and the Grenadines during the next 72 hours. Some scattered showers are forecast for tonight over the mainland. However, as time passes, a favourable upper level is likely to enhance shower activity and increase the chance of a few isolated thunderstorms. Therefore, from tomorrow afternoon into the weekend, occasional light rain, and some showers with a moderate (50%) chance of isolated thunderstorms are possible across Saint Vincent and the Grenadines.

The Atlantic High Pressure System is causing increased wind speeds across our area. Meanwhile, a weak shearline across the Northern Windward Islands is gradually dipping southward with occasional cloudiness and few showers across St. Vincent and the Grenadines (SVG). Scattered showers are expected by late Tuesday and instability could linger a few days.  

Fresh to occasionally strong (30 – 45 km/h) north-easterly breeze could increase Tuesday night (40 - 50 km/h) in exposed areas. Wind speeds should be generally reduced by Friday. 

Moderate (1.5 – 2.5 m) sea conditions with east north-easterly swells are across SVG and could become rough

A surface to mid-level trough will continue to affect Saint Vincent and the Grenadines during the next 72 hours. Some scattered showers are forecast for tonight over the mainland. However, as time passes, a favourable upper level is likely to enhance shower activity and increase the chance of a few isolated thunderstorms. Therefore, from tomorrow afternoon into the weekend, occasional light rain, and some showers with a moderate (50%) chance of isolated thunderstorms are possible across Saint Vincent and the Grenadines.

The Atlantic High Pressure System dominates across the region, with occasional showers as brisk winds push low-level clouds across the islands. A few showers are possible early morning Monday, associated with a weak low-level shearline across the Northern Windward Islands. As the shearline dips southward and lingers across our area, the chance for scattered showers across St. Vincent and the Grenadines (SVG) increases during Tuesday.  

Moderate to occasionally fresh (25 – 40 km/h) north-easterly breeze and occasional gusts are expected, with a temporary increase (up to 50 km/h) possible during Tuesday night.

Atlantic High Pressure System should dominate across the region for the next few days with occasional showers across St.Vincent and the Grenadines (SVG), as brisk winds push low-level clouds across the area. Model analysis now indicates the low-level shearline could approach the northern Windward Islands late Sunday. 

Moderate to fresh (25 – 40 km/h) east north-easterly breeze could be occasionally reduced (15 - 25 km/h) during the weekend, as a shearline approaches the area. Fresh north-easterly trades with higher gusts (30 - 45 km/h) are possible late Sunday

Atlantic High Pressure System should dominate across the region for the next few days. Dry air is across St. Vincent and the Grenadines (SVG), but occasional showers are likely tonight, Friday and Saturday, as brisk winds push low-level clouds across the area. A low-level shearline could approach the island chain late Sunday, possibly increasing cloudiness with showers.

Moderate to fresh (25 – 40 km/h) east north-easterly breeze could be temporarily decreased (15 - 25 km/h) Sunday evening as a shearline approaches the area.  

Slight to moderate (1.2 – 2.0 m) sea conditions are across our islands, with easterly swells.

The surface to mid level Atlantic high pressure system is forecast to dominate the weather pattern across the island chain during the next 72 hours. Therefore, mostly fair to occasionally cloudy skies will be experienced, and the likelihood of some showers tonight and tomorrow morning as low level moisture move along with a moderate to fresh easterly wind flow.

A low-level trough is crossing the islands and scattered showers across the Grenadines this morning could continue across St. Vincent and the Grenadines (SVG) this afternoon, possibly increasing tonight. Shower activity is likely to decrease during Tuesday. Thereafter, occasional showers can be expected as low level-moisture/clouds move along with the wind-flow.
Moderate (20 - 35km/h) east south-easterly breeze should increase to fresh (up to 40km/h) by Tuesday, turning east north-easterly late Wednesday as High Pressure builds across the region.

Moderate sea conditions are across our islands, with northerly swells

Saint Vincent and the Grenadines will experience fair conditions interchange with occasional scattered showers during the next 72 hours. A light north easterly wind flow will become mostly easterly and increase in speed (20km/h to 40km/h) from Sunday into Monday as a ridge of high pressure builds.  Smooth to slight sea conditions will be noticeable, before moderate conditions (1.5m) return to the east coast around Monday. There will be no significant haze intrusion within this forecast period.

 

A few shallow showers are forecast across Saint Vincent and the Grenadines during the next 24hours. The chance of any significant shower activity is likely to take place on Thursday, with instability lingering into Friday as a shearline coupled with an upper level trough move across the island chain.
