The Saint Vincent and the Grenadines Meteorological Services is monitoring an area of instability associated with a dissipating frontal boundary.
This activity, which has been affecting the Leewards and northern Windward Islands over the past 24 hours, is expected to move southward across our area by tomorrow, Thursday, 20th April, and persist to the end of the week. As a result, a gradual increase in shower activity and possible isolated thunderstorms are likely across Saint Vincent and the Grenadines.
This activity is likely to peak in intensity on Thursday, as the mid to upper atmosphere become more favorable for enhancement. Current model projected rainfall accumulations are approximately 2 inches, or up to 50 mm, with higher amounts in mountainous areas. Residents and motorists are being advised to be vigilant and exercise caution during the passage of this system.
Additionally, moderate to rough northerly swells are expected during the next 24 hours, peaking near 13.0 feet. A High-Surf Advisory and a Small Craft Warning are in effect for above normal seas. Small craft operators and sea bathers are advised to exercise caution.
The Saint Vincent and the Grenadines Meteorological Services will continue to monitor the situation, and if necessary, provide updates.
