Brief scattered showers will continue across SVG today, with isolated showers possible on Thursday as weak pulses embedded within a predominantly easterly wind flow continue to move across SVG. A tropical wave currently located in the mid Atlantic, from 11N southward, is approaching the Guianas. A veering of the winds will allow for a south easterly flow to generate moisture from this region across Saint Vincent and the Grenadines around Friday. The Grenadines will be affected first, as moderate showers and gusty winds are forecast across Saint Vincent and the Grenadines. The chance of isolated thunderstorms is high around Friday afternoon. Model guidance is indicating that moderate showers from this wave will linger into Saturday morning.
Winds will blow predominantly from the east at 15km/h – 25km/h, becoming 25km/h- 30km/h from Wednesday night. An east south easterly flow is likely from Thursday, and by Friday, winds speeds of approximately 25km/h – 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 possible around Friday into Saturday due to increase gusty winds. In addition, there will be no significant haze intrusion within this forecast period.
