The atmosphere is moist and occasional showers are forecast across Saint Vincent and the Grenadines during the next 72 hours. Showers are likely to be moderate becoming heavy at times with possible isolated thunderstorms due to the presence of an upper level trough that will be lingering around the region for the next few days.

Model guidance is indicating that ‘flare - ups’ (sudden moderate to heavy showers and thunderstorms) are possible tonight and tomorrow. Instability will continue on Tuesday night into Wednesday, triggering some occasional light showers.

Moderate to heavy showers, possible isolated thunderstorms and gusty winds are forecast around Wednesday night into Thursday as another tropical wave inches closer to the island chain.

A moderate easterly wind flow (15km/h-30km/h) will move across the islands, backing to east north east (ENE) around Tuesday night. An easterly flow will return by Wednesday, increasing to fresh breeze, becoming gusty at times near showers from Wednesday night. 

Sea conditions will be slight to moderate (1.2m-2.0m) in open waters today and Tuesday, with deterioration possible (2.5m) on the eastern coasts from Wednesday as wind speeds increase. Small craft operators and sea bathers should exercise caution around this time.  In addition, there will be no significant haze intrusion within this forecast period.
