A couple lower-level troughs just east of the island chain are expected to cross the islands with little fanfare due to limited moisture content. Dry conditions remain above 850mb (4800ft) which also limits any shower activity. Few isolated showers are possible tonight ahead of a trough-axis on Monday. Models indicate isolated showers could be expected on Tuesday behind the first trough, with better chance
for few showers behind the second trough late Wednesday into Thursday. The latter, due to the Atlantic High Pressure Center possibly shifting eastward along with an upper level-long-wave trough; resulting in marginal increase in mid to upper level moisture. This eastward shift would accommodate two low pressure areas deepening off the South-east US (seen in 18z analysis below compliments NOAA) and another off the North-east US coast in the Western Atlantic by Tuesday this week.
Expect gentle (10 - 20km/h) breeze to increase to moderate overnight with varying directions. Over the next few days, the crossing of troughs could result in occasional reduction of wind speed from moderate to gentle breeze during afternoons into evening.
Slight to moderate sea conditions (1.0 – 1.5m), are expected across St. Vincent and the Grenadines (SVG), with wave heights gradually rising by midweek.
No significant dust concentrations are expected across our area, but very slight haze may be noticeable on our horizon due to patches of thin dust concentrations….JMCD
