Weather Outlook 6th January 2019 (12 noon)

A shearline feature lingers across the Central Windward Islands, with isolated shower activity north of our islands today. A southward dip of the shearline should bring scattered showers across SVG by early morning Monday, decreasing by afternoon. Late Tuesday into Wednesday, mid to upper level features and moisture could support another lower-level shearline feature with some showers. 

Moderate (20 -30km/h) east south-easterly wind-flow bringing equatorial moisture/few isolated showers by evening. Wind speeds should increase to fresh (up to 40km/h) breeze and backing overnight into Monday. Gentle to moderate breeze by Tuesday afternoon should be veering by Wednesday to east south-easterly.

Slight to moderate seas (1.0 - 2.0m) are expected across SVG, slightly rising on Monday to 1.2 – 2.2m in response to fresh breeze.  

Barometric readings should range 1015 - 1018mb, falling by Monday afternoon as a couple Low Pressure Systems move eastwards in the North Atlantic. 

Hazy conditions are expected to increase by evening as a mass of dust concentration approaches from the east with PM2.5 levels nearing 14µg/m3 and PM10 levels nearing 23 µg/m3 by Monday night. ….JMCD
