Weather Outlook 9th September 2019 (6 pm)
Moisture associated with a weak tropical wave will affect Saint Vincent and the Grenadines tonight. This wave is forecast to affect mostly Grenada and Trinidad and Tobago tonight into tomorrow. Nevertheless, some brief occasional showers are likely across SVG tonight. Meanwhile, a surface to mid level trough will continue to affect the Northern Windward Islands.
Model guidance is indicating a drying of the low and mid levels as the night progress and some fair conditions are likely across SVG on Tuesday into Wednesday as a weak ridge pattern becomes the dominant feature. An approaching tropical wave will be in the vicinity around Wednesday and moisture levels will once again increase. Model guidance is indicating mostly the Northern Windwards to be affected with some scattered showers possible across SVG as Wednesday progress. Lingering moisture from the wave and further instability can result in an increase of shower activity and possible isolated thunderstorms across SVG on Thursday.
North-easterly winds at 15km/h-30km/h will be experienced tonight, with a gradual decrease in wind speeds becoming more south-easterly around Thursday. Sea conditions are forecast to be slight to moderate (1.0m-1.5m) this evening becoming generally slight by Thursday. No significant haze intrusion is anticipated within this forecast period.
