An induced mid to lower-level cyclonic circulation across the Leeward Islands continues to fuel the unstable conditions lingering across Eastern Caribbean. Across St.Vincent and the Grenadines (SVG), elevated moisture levels throughout the atmosphere could trigger occasional light to moderate showers tonight. The Flood–watch is now discontinued, but a Flash flood alert is in effect for residents and motorists in areas prone to flash-flooding…See image at 5:20pm compliments RAMMB.
Unstable conditions across the Leewards and northern Windward Islands could spread southwards across our area this evening into Friday, bringing occasional showers and isolated thunderstorm activity.…motorists and residents should exercise caution as shower activity could be enhanced (become moderate to heavy showers overnight/early morning) with an upper-level trough deepening near the Eastern Caribbean inducing lower-level trough.
Unstable conditions associated with the passage of a tropical wave resulted in pockets of moderate to heavy showers across St. Vincent and the Grenadines during the earlier hours of this morning. However, by mid- morning, improvements in the weather conditions with mainly partly cloudy skies were noticeable.
Mostly fair weather conditions are expected across St. Vincent and the Grenadines (SVG) during the next 12-18 hours, as the Atlantic High Pressure System continues to be the dominate feature.
Unstable conditions associated with a low level shearline will remain the dominant feature. However, due to a dry and stable mid-level atmosphere, showers across Saint Vincent and the Grenadines (SVG) will continue to be short-lived, and light to moderate in intensity
Mostly fair weather is expected across St. Vincent and the Grenadines (SVG) during the next 24 to 36 hours, as the Atlantic high pressure system continues to be the dominate feature. However, patches of low level clouds moving along an easterly wind flow are likely to generate occasional isolated showers.
The Atlantic high pressure system has re-established itself across the islands. As a result, occasional brisk easterly winds can be expected across the Eastern Caribbean Islands. Due to a dry and stable atmosphere, showers across Saint Vincent and the Grenadines (SVG) are likely to be limited, and light to moderate in intensity
The Atlantic High Pressure System will remain the dominate feature across our islands during the next 24 hours. As a result, occasional cloudy skies and a few brief passing showers can be expected.
