The Saint Vincent and the Grenadines Meteorological Office is monitoring the progress of a Westward moving Tropical Wave now located in the Central Atlantic.
The wave should move S.V.G. late Sunday night into early Monday morning. An increase in shower and thunderstorm activity is expected.
The tropical wave extends from 08N to 17N with axis near 50W moving W at 20 kt over the past 24 hours. The wave is in a region of unfavorable deep layer wind shear and dry air is in the N-NW wave environment according to CIRA LPW imagery from the surface to 850 mb as well as water vapor imagery.
However, abundant shallow moisture in the remainder wave environment along with a diffluent flow in both the middle and upper levels support scattered heavy showers from 09N to 14N between 47W and 53W.
The Met Office says weak instability will continue to affect the islands during the next 24 hrs producing occasional cloudiness and scattered showers.
