A tropical wave would affect the islands late tonight into Monday morning, resulting in possible moderate to heavy showers and isolated thunderstorms across St. Vincent & the Grenadines. Residents and motorists should exercise caution. Instability trailing the wave could see cloudy conditions persist into the evening. On Tuesday afternoon another tropical wave should begin to affect the islands. On Wednesday, a shearline could generate some cloudy skies, triggering a few scattered showers in the process.
