Some scattered showers will continue tonight with isolated activity possible along Thursday as weak pulses embedded within the wind flow continue to move across SVG. An approaching tropical wave is on course for the Guianas(South America) and a south easterly wind flow would assist with the migration of moisture from that region towards our islands around Friday. The Grenadines will be affected first, with moderate showers and gusty winds forecast to spread towards the mainland shortly after. The chance of thunderstorms is high around Friday afternoon. Model data suggests significant rainfall accumulation is likely across the weekend. Therefore, the St.Vincent and the Grenadines Meteorological Service will continue to monitor and issue the necessary updates/advisories.
Gentle to fresh(15-30km/h) east north easterly trades will cross the islands tonight. An east to east south easterly flow is likely from Thursday, and by Friday, winds speeds of approximately 25 – 40km/h will move across the islands. Seas will remain slight to moderate in open waters, with swells peaking at 1.0m on the western coasts and 2.0m on the eastern coasts. Deterioration in sea conditions is quite possible around Friday into Saturday due to the anticipated increase in wind speeds. In addition, slight haze intrusion is also likely from late Thursday
