A WATCH remains in effect for Saint Vincent and the Grenadines... This watch may be upgraded if flooding becomes imminent. Unstable conditions with few trough systems are expected across the islands until mid-week. More showers are expected overnight as a weak trough in the low to mid levels crosses the area with enhancement by an upper level trough dipping across the Eastern Caribbean.
During Monday, an east south-easterly wind flow bringing equatorial moisture across our area could result in showers increasing towards the afternoon. A mid- level trough approaching late Monday could maintain shower activity from early Tuesday. Another mid level trough oriented north-south is expected late Wednesday. Meanwhile, favourable upper level conditions could occasionally enhance showers/thunderstorm activity. These unstable conditions should be lifting from our area during Thursday.
Expect moderate (20 - 30km/h) breeze tonight, decreasing to gentle (10 - 20km/h) late Monday. On Tuesday, south south-easterly wind flow is expected, becoming a light breeze by evening then increasing to gentle early Wednesday.
A 1040 mb Atlantic High Pressure dominates the far North Atlantic, while mean sea level (MSL) readings across our area should be ranging 1008 – 1010 mb overnight. An increase is possible by Monday ranging 1010 – 1012 mb while a 1026 mb High enters the Atlantic off the USA east coast. Small areas of low pressure could deepen north-east of the island chain late Wednesday keeping a check on MSL readings.
Slight to moderate seas ranging 0.5m -1.5 on west coasts and 1.2m -1.8m on the east coasts, gradually falling to slight (0.5m - 1.2m) by late Tuesday across SVG.
