Some moisture and wind convergence could result in few scattered showers overnight with shallow low level cloud patches. A weak trough could bring marginal increase in mid-level moisture, resulting in increased cloudiness and scattered showers late Tuesday into Wednesday (especially across the Southern Grenadines). Thereafter, the Western Atlantic High Pressure should be rebuilding
by late Wednesday, with few isolated showers possible on Thursday.
Moderate north-easterly trades (20 - 30km/h) can be expected overnight, veering to east south-easterly early Tuesday. Direction should be backing with moderate to fresh (20 - 35km/h) north-easterlies returning Tuesday night.
Wave heights across St. Vincent and the Grenadines (SVG) are decreasing, with slight to moderate seas peaking near 1.5m on west coasts and near 2.2m on east coasts overnight. Moderate to rough northerly swells on the eastern side of Barbados (beyond 59W) in the open Atlantic Ocean, are pushing southward to the Guianas to decrease by late Tuesday. Wave heights should be rising again during Thursday with northerly swells possible across SVG by Friday afternoon…Small craft operators and sea-bathers should be alert...
