Today's forecast:
Synopsis: A surface to mid level trough system is affecting the islands
Forecast: Fair to occasionally cloudy with some showers, increasing towards afternoon
Weather Advisory/Warning: A Flood Watch is in effect for SVG…flooding and land slippage still possible
This watch may be upgraded if flooding becomes imminent.
Outlook:
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 - 30 km/h) breeze tonight, decreasing to gentle (10-20 km/h) late Monday. On Tuesday, south south-easterly wind flow is expected, becoming a light breeze by evening then increasing to gentle early Wednesday.
Slight to moderate seas ranging 0.5 m - 1.5 m on west coasts and 1.2 m – 1.8 m on the east coasts, gradually falling to slight 0.5 m -1.2 m by late Tuesday across SVG.
