Dry cyclonic low-mid level circulation is expected to cross the Trinidad area today, but models indicate isolated pockets of moisture could cross our islands (SVG) as the north-south oriented trough trails the low increasing the chance (though slight) of few scattered showers Monday night into Tuesday morning.
Some moisture trailing the trough could cross our area bringing few scattered showers late Tuesday into early Wednesday. Meanwhile, a mini-High Pressure should build temporarily across our area Wednesday, to be replaced by a mid level trough on Thursday.
Moderate easterly breeze should continue today, veering slightly to east south-easterly and becoming possibly gentle by evening. The approach of a weak surface to mid-level trough should result in winds backing to east north-easterly tonight, gradually increasing (moderate to fresh) by Tuesday afternoon.
Mean sea-level pressure which dipped slightly overnight (1010-1012 mb), is expected to rise again Tuesday (1013-1016 mb).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 1.8 m on east coasts) in open water, possibly rising again by mid-week.
Few patches of Sahara dust could cause occasional fluctuations in visibility over next few days.
Note: Undersea volcano 'Kick em Jenny', north of Grenada near 12.18N 61.38W, is in a state of unrest. The government of Grenada advises mariners to observe a 5 kilometer (3.1 nautical miles) exclusion zone around 'Kick em Jenny'. Please see www.nadma.gd for additional information.
