Met office 72 hour forecast notes increased rains

In their 72 hour outlook update on 29th June 2021, the SVG Meteorological Services noted increased rain and wetness expectancy.

“Moisture will increase by this evening (Tuesday, 29th June 2021) as instability from a strong tropical wave approaches the islands. Generally, cloudy skies and showers with the chance of isolated thunderstorms are forecast Tuesday night into Wednesday; intensifying from Wednesday afternoon into Wednesday night as this broad wave moves across Saint Vincent and the Grenadines. Model guidance is indicating approximately 35mm of rainfall accumulation by 8 o’clock Wednesday night. Showers are forecast to continue throughout the night as the wave axis crosses over the islands.  A further 25mm is possible by early Thursday night as the wave moves west north-westward to affect the Northern Windward Islands.”

Further to this “another well defined tropical wave traversing the Atlantic, and based on model guidance it is likely to develop further as it crosses SVG around Friday night...” According to the 72 hour outlook, over 2 inches of rain is expected on the weekend beginning Friday. The continued presence of Sahara Dust is also anticipated. As weak and unstable conditions continue, ensure your home and surroundings are clear of debris, clear drains and gutters, and monitor your environment for hazards which may arise.
