A low-level trough would begin to affect St. Vincent & the Grenadines from tonight, generating cloudy skies and triggering some scattered showers with varying intensities into and across Sunday. Instability trailing this feature could result in cloudy conditions again on Monday. Meanwhile, a plume of Saharan dust is expected to thicken across our islands by late Sunday. Persons with respiratory concerns should be aware that air quality may be reduced and take the necessary precautions.
