Varying concentrations of Saharan dust will move across the islands over the next few days, possibly increasing around Sunday afternoon before thinning out. Apart from a few light early morning showers, fair conditions should be noticeable during Sunday. However, during the night, heading into Monday, a tropical wave would affect the islands 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 would begin to affect the islands.
