Weather Outlook 11th July 2019 (12 pm Noon)

The Atlantic High Pressure System will remain the dominate feature across our islands during the next 6-12 hours, resulting in occasional cloudy skies and brief passing showers.

Thereafter, an approaching tropical moving westward near 20 mph will move across the island chain. This wave is expected to generate pockets of moderate to heavy showers and thunderstorms across St. Vincent and the Grenadines (SVG), tomorrow through Saturday. Due to the latest projected rainfall accumulations, a Weather Advisory is likely to come in effect for SVG during its passage.  Residents and motorists in low lying areas and near rivers and streams should be alert.

Meanwhile, another tropical wave presently analyzed over the Eastern Atlantic is moving near 15 -20 mph with disorganized showers and thunderstorms.  Some slight development of this wave is possible during the next two days, before conditions become less favorable over the weekend. This wave is expected to affect the islands during Sunday.

Northeasterly winds ranging between 20 to 30 km/h (12 to 19 mph) are expected to gradual increase; peaking near 50 km/h (31 mph) by Sunday.

Slight to moderate easterly sea swells are forecast during the next 48 hours with swells peaking near 2.0 meters (7.0 feet). However, an increase to 2.5 meters (8.0 feet) is expected by Saturday.

No significant Saharan dust haze is expected during this forecast period.

Additionally, Tropical Storm Barry, the second named storm of the 2019 Atlantic Season, has recently formed over the North Central Gulf Coast.  This system does not pose a threat to SVG.
