Showers and thunderstorm activity could become heavy, with squally conditions possible across St. Vincent and the Grenadines (SVG) Thursday afternoon…Significant rainfall accumulations are very likely…Take precautions; in areas prone to flash-flooding and land-slides, or near rivers and streams. Showers and thunderstorm activity could continue into Friday, but moderate/thick haze due to Saharan dust concentrations can be expected by evening. A few showers and isolated thunderstorms inter-mixed with hazy conditions can be expected during Saturday.

At short notice, the St Vincent and the Grenadines Meteorological Service may issue a Flash-Flood watch/warning. 

Moderate to fresh (‘~25 – 40 km/h’) easterly breeze across our islands could turn east south-easterly early Thursday, with occasional strong gusts/squally (40 – 50 km/h) conditions across SVG Thursday afternoon into the night.

Swell heights are rising, possibly nearing 1.8 m on western coasts and 2.5 m on eastern coasts by Thursday evening…Small-craft operators and sea-bathers should exercise caution for above normal east north-easterly sea-swells and gusty winds…gradually decreasing Friday to range 1.2 m to 2.0 m by evening.
