Apart from Fair to partly cloudy skies with localized showers this afternoon, (wake cloud west of Barbados towards mainland St.Vincent) generally small patches of fair weather/shallow clouds should drift across the islands with insignificant shower activity.
Dry cyclonic low-mid level circulation is expected to cross the Trinidad area Monday, but models indicate pockets of moisture converging across our islands (SVG) increasing the chance of few scattered showers Monday night into early Tuesday morning as a north-south oriented trough trails the low. Moisture should converge across our area bringing few scattered showers late Tuesday into Wednesday. Meanwhile, a mini-High Pressure should build (due) temporarily across our area late Wednesday, to be replaced by a mid level trough on Thursday.
Moderate (20-35km/h) east north-easterly breeze should continue this afternoon, veering to east south-easterly late Monday. The approach of the trailing trough should result in winds backing again to east north-easterly late Monday and becoming possibly gentle. Winds should gradually increase (moderate to fresh) by Tuesday afternoon.
Mean sea-level pressure could dip slightly later tonight (1010-1012mb), generally rising again Tuesday (1013-1016mb).Harmless small streaks of Sargassum sea weed are along coastal areas (creating smelly fumes). Seas should remain slight to moderate (up to 1.2m on west coasts and up to 1.8m on east coasts) in open water, possibly rising again by middle of next week.
Thin patches of Sahara dust cause fluctuations in visibility, but a general thickening of dust concentrations is expected overnight Tuesday, to thin out by Thursday.
