Weather Outlook 8th August 2019 (6 pm)

  • Outlook

The Atlantic High Pressure is dominant across the islands. A weak trough should trail across the islands on Friday, followed by a low level trough creating weak instability with scattered showers on Saturday. Gentle to occasionally moderate (10 – 30km/h) south-easterly wind-flow should become north-easterly by late Friday. 

Sea conditions are slight to moderate (1.0 - 2.0 m) in open water with east north-easterly swells across St.Vincent and the Grenadines (SVG).  

Slight haze should be noticeable on our horizon by late Thursday, occasionally thickening to moderate haze on Friday which could limit shower activity and reduce visibility. Visibility should be improved again by Saturday.

Barometric readings should range 1014 - 1017mb, dipping slightly (1013mb) on Saturday.
