The low pressure area north-east of the island chain developed into Tropical Storm Sebastien and is moving away from the islands...NOAA 5pm forecast track and Satellite image at 4:30 pm compliments CIMMS below... A trough associated with ‘Sebastien’ lingered close to our islands with a few showers this afternoon. Scattered showers and isolated thunderstorms are likely across St. Vincent and the Grenadines (SVG) as the trough detaches and crosses the islands during Wednesday.
Shower activity should be decreased Wednesday night and another trough should be approaching the region late Thursday into Friday.
Gentle to moderate (15 - 30 km/h) north-easterly breeze could become light by Thursday, with varying directions and calm at times.
Slight to moderate (1.0 – 1.5 m) sea conditions with north-easterly swells are across our islands, temporarily rising (1.0 - 2.0m) late Wednesday to Friday morning. Slight haze tonight, should thin out early Wednesday.
