The Western Atlantic High Pressure is gaining dominance across the Leeward and Northern Windward Islands, but a deep ‘cut-off low’ pressure area is deepening in the Central Atlantic creating instability across the southernmost section of the island chain. This ‘cut-off low’ feature, could create favourable mid to upper level (tropical upper tropospheric trough-TUTT) support for shower activity across the southernmost islands as weak troughs propagate across the island chain. Occasional cloudiness and showers across St. Vincent and the Grenadines (SVG) could spike with shower activity late Saturday
into early Sunday and again late Tuesday.
Breezy conditions can be expected with moderate to fresh (25 - 40km/h) east north-easterly trades across our islands with occasional strong gusts. A reduction in wind speeds can be expected by late Sunday with the approach of couple lower level troughs.
East north-easterly sea-swells are rising and moderate sea conditions are expected across SVG. On the west coasts, sea-swells could range between 1.2 and 1.8m while east coasts can expect sea-swells between 1.5 and 2.5m. Mariners are advised to exercise caution as rising wave heights are possible with steady brisk wind speeds….Wind speeds and wave heights should be reduced by late Sunday.
In upcoming days, barometric readings should fluctuate between 1012mb and 1017mb across our area, with the passage of couple lower level troughs.
No significant dust concentrations are expected across our islands over the next few days.
