Tropical wave, trough system to affect St Vincent

High wind advisory, DVG

A tropical wave is forecast to move across the island chain around Wednesday generating cloudy conditions and some showers across Saint Vincent and the Grenadines.

An upper-level trough around this time period can also lend some support to this wave resulting in possible isolated thunderstorms.

By Thursday afternoon, model guidance is indicating a drying out of the atmosphere and some fair conditions along with the intrusion of the Saharan dust may be observed.

Generally, easterly trades, varying from ENE-ESE on occasions at 20km/h to 40km/h are forecast. Seas are to remain moderate (1.5m-2.0m) in open waters, increasing to 2.5m on the east coast around Thursday.
