A shearline moved across the island chain overnight with occasional cloudiness and scattered showers and few isolated thunderstorm activity across St.Vincent and the Grenadines (SVG). Another shearline/trough is expected by Saturday afternoon. In the intervals fair conditions are expected as the Atlantic High Pressure System struggles to rebuild across our area. Slight hazy conditions are expected over the weekend.
Lower level moisture below 700mb (cloud patches) ahead of an approaching tropical wave, should result in scattered showers from late Sunday.
A cluster of showers and thunderstorm activity with a 1012mb low pressure area associated with a tropical wave in the Central Atlantic Ocean, about 1400 miles east-southeast of the Windward Islands is being monitored. Deep layered shear is favourable across the area, which could allow for some development during the next few days as it moves westward and nears the Lesser Antilles by mid-week.
Gentle to moderate (10 – 25km/h) east south-easterly breeze should continue, increasing by Sunday to moderate and fresh (25-40 km/h). Directions should back to east north-easterly late Sunday.
Sea conditions across SVG should be slight to moderate (1.0 – 1.5m), increasing slightly by Sunday to peak 2.0m on east coasts. Barometric readings should range 1014 - 1017mb over the next few days.
Tropical waves and troughs between west coast Africa and Lesser Antilles:
Along 22/23W from 21N southward, moving W around 10 kt with scattered moderate to isolated strong convection is from 09N-14N between 19W-31W...2280miles away…vicinity next weekend
A cluster of showers and thunderstorm (near 41.7W 9.8N at 8am today) about 1400 miles east-southeast of the Windward Islands moving westward… vicinity of Lesser Antilles by Wednesday/Thursday 29th
Shearline/trough along 51/52W from 06N-21N, moving W at 15-20 kt with little/no significant convection at this time, but scattered moderate convection is from 08N-11N between 45W-49W...540miles away…vicinity Saturday 24th
