St. Vincent and the Grenadines can expect breezy conditions to persist this week, even as Saharan dust haze will continue to cross the country over the next 72 hours.
In a 72-hour weather outlook issued at noon on Monday, meteorological forecaster Gregory Cato said residents should remain alert for reduced air quality and visibility.
“A ridge pattern would dominate the conditions within the next 48 hours, allowing for a few sporadic showers,” Cato said, adding that around late Wednesday, unstable conditions will instigate unsettled conditions across the country.
“This would continue on Thursday. Residents should remain alert,” Cato said.
He said fresh to strong (approximately 30-45 km/h) east-northeast trade winds will cross the islands within the next 36 hours.
“Consequently, seas will become further agitated,” Cato said, and announced a small craft and high surf advisory for SVG and its coastal waters.
Seas are moderate in open water with swells increasing to beyond 2.5m (8.2 ft) in the next few days.
“Only vessels capable of withstanding swells of these magnitudes should venture out. Sea bathers are advised to stay out of the water,” the forecaster said.
A small-craft advisory is issued when sustained winds of 37 to 46 km/h (23 to 29 mph) and/or sea swells of 2.5 to 3 meters (8 to 10 feet) are affecting or forecast to affect the marine area within the next 36 hours.
A high surf advisory is issued when breaking wave action is forecast to pose a threat to life and property within the surf zone during the next 36 hours.
“Large waves and dangerous rip currents will create unsafe conditions for small-craft operators, particularly on the northern and eastern coastlines. These conditions may become even more adverse at times of high tide,” Cato said.
The forecaster said the maritime advisory may be discontinued at 6 a.m. Thursday or sooner if conditions improve. It may also be extended if conditions warrant.
