The St. Vincent and the Grenadines Meteorological Services in its midday weather report stated that a weak lower level trough would be affecting the island.
A trough is an elongated (extended) region of relatively low atmospheric pressure, often associated with fronts. Troughs may be at the surface, or aloft, or both under various conditions. Most troughs bring clouds, showers, and a wind shift, particularly following the passage of the trough.
The forecast calls for partly cloudy to cloudy skies, with scattered showers, seas are expected to be slight to moderate in open water; 1.0m to 2.0m.
The met office would update at 6 pm.
