Few isolated showers are forecast tonight across Saint Vincent and the Grenadines as a weak tropical wave affects the island. An increase in cloud cover and showers is expected on Tuesday, but model guidance suggests that this instability may be confined more to the south of the mainland and over the Grenadines. By Wednesday, expect a mixture of cloudy skies and sunshine as the Atlantic high-pressure system regains its dominance across the region. Similar conditions from the previous day are anticipated on Thursday.
