Unstable conditions due to a mid-upper level trough which has deepened to the lower levels, resulted in continued cloudiness with light to moderate rain, pockets of moderate to heavy showers and isolated thunderstorm activity across St. Vincent and the Grenadines over the past couple days. A deepening low to mid-level trough over the South-Eastern Caribbean could maintain unstable conditions continuing into
the weekend, maintaining the potential for further outbreaks of moderate to heavy showers across SVG. Some slopes are now vulnerable to slippage and isolated cases of flooding could continue in areas prone to flooding.
At our Argyle Station, between the period Tuesday 6:00pm to Thursday 6:00pm over 4 inches (108.7 mm) rainfall was recorded. Latest model analysis indicate close to 1 inch (25 mm) overnight, 2 inches (40 - 50 mm) on Friday, near 2 inches (35 mm) Saturday, just under 1 inch (20 mm) on Sunday.
A FLOOD WARNING is in effect for Saint Vincent and the Grenadines until 6 pm Friday 19th October, 2018... This warning may be extended if conditions warrant.
Expect fresh (30 - 40km/h) easterly breeze to continue tonight into Friday. The wind direction should back to east north-easterly Friday afternoon. A reduction in speeds should be noticeable during Saturday, varying in direction and becoming light by evening continuing on Sunday.
There are patches of dust which are reducing visibility as well as inhibit shower activity. A break in the patch could allow for some moderate/heavy showers overnight. Hazy conditions should be across our area again tomorrow Friday, alternating with shower activity. By Saturday afternoon, the dust should give way to showers associated with the possibly deepening mid-level trough.
Mean sea level readings should be dipping to 1010 -1012mb by early morning, further to 1008 – 1010mb late Saturday with a 1040mb Atlantic High dominating the far North Atlantic by Sunday.
Moderate seas are across SVG with wave heights on west coast could peak near 1.8m and on east coasts near 2.4m….Mariners should continue to exercise caution due to above normal swells and gusty winds. A reduction in wave heights could start late Friday, becoming slight to moderate (0.5m - 1.5m) by Sunday.
