A Low-Pressure system anchored in the north-central Atlantic has been generating large swells which are propagating southwards into the Lesser Antilles.
Northerly to north-easterly swells of 3.5 to 4.0m (10 to 13 ft) have been affecting the coastal waters around St. Vincent and the Grenadines, particularly on the west, north and eastern sides of these islands.
This activity is expected to persist for the remainder of the week and may become even more adverse at times of high tide.
As a consequence, a HIGH-SURF ADVISORY and SMALL-CRAFT WARNING is in effect for St. Vincent and the Grenadines as of Tuesday 7th March through 6:00 p.m Saturday 11th March 2017.
Large waves and dangerous rip currents can be expected mainly along the west, north, and east as of St. Vincent and the Grenadines which will create unsafe conditions for small-craft operators.
A small-craft Warning means in this case that wind speeds of 25 to 33 knots (46 to 61 km/h) and/or seas equal to or greater than 3m (10ft) will be affecting the marine area.
A High-Surf Advisory is issued when breaking wave action poses a threat to life and property within the surf zone.
The Barbados Meteorological Services and the St. Vincent and the Grenadines Meteorological Services will continue to monitor the situation.
