Weather Outlook 27th January 2019 (12 noon)
A lower level shearline/trough feature is affecting the Windward Islands, with occasional showers across our islands (St.Vincent and the Grenadines). Few occasional showers this afternoon should be reduced by tonight as the shearline is expected to shift westward into the Caribbean Sea. Meanwhile, the Central Atlantic High Pressure System could struggle to rebuild, with the presence of a deep layered
low in the Atlantic. An induced trough propagating from the ‘Low’ could be deepening across our islands during Tuesday with a dry elongated circulation across our islands. Some cloudiness with few showers should be crossing our area behind the trough axis late Tuesday into Wednesday.
Expect moderate (20 - 30km/h) east south-easterly wind flow this afternoon, increasing to fresh (up to 45km/h) tonight. Increased wind speeds may not be sustained beyond Monday evening due to a struggling High Pressure System. Wind direction should then be backing to north-easterly, varying in direction during Tuesday as another trough (dry axis) crosses the area.
Wave heights have decreased with slight to moderate sea swells ranging 1.2 – 2.2m across St. Vincent and the Grenadines; originating from north north-east should be slightly falling to range 1.0 – 2.0m by late Monday.
Barometric readings should fluctuate between 1013 - 1018mb over the next few days with the presences of the Low and Atlantic High Pressure System.
No significant dust concentrations are expected across our area over the next few days...JMCD
