The Central Atlantic High Pressure System is the dominant feature across the islands bringing occasional brisk winds and lower level cloud patches, hence possible brief showers. A shift to the eastern Atlantic is possible by Saturday, with our islands positioned on the southwestern edge of the High Pressure System.
This will allow for a weak area of low pressure near northern Venezuela to spread marginal moisture across our area, with occasional cloudy skies and few showers possible over the weekend into early next week. Dryer upper levels should inhibit any significant rainfall accumulations.
East south-easterly moderate (20 - 35km/h) breeze should continue across our islands this afternoon, backing to north north-easterly and becoming occasionally fresh (up to 40km/h tonight. Wind directions should vary over the weekend, but speeds should be increasing late Monday with gusts near 50km/h.
Slight to moderate sea conditions with swells peaking near 1.2m on the west coasts and near 2.2m on the east coast, are expected to rise across SVG tonight. Wave heights could range 1.2-1.8m on the west and 1.5 – 2.5m on the east during the weekend. Meanwhile, small craft operators should note that northerly swells are expected beyond 60 degree longitude overnight and beyond 55degrees longitude during Saturday. Slight reduction in wave heights is possible by late Sunday before increasing again during Monday… this may trigger advisories/warnings.
Barometric readings now ranging 1017 – 1019mb, could be fluctuating during the weekend as the High Pressure shifts eastward and weakens, as two Low Pressure areas move off the North American coast.
Slight haze on our horizon due to patches of dust concentrations of varying intensity, could result in occasional reduced visibility.
