A strengthening Atlantic High Pressure System is expected to generate strong surface winds and above normal north-easterly swells across Saint Vincent and the Grenadines into late Sunday.
During this time period, strong winds with speeds of 25 to 33 knots (47 to 61 km/h) with higher gusts, and rough seas with swells peaking to 3.0 meters (10 feet) are anticipated. As a result, a High-Wind Advisory and Small-craft Warning will be in effect for Saint Vincent and the Grenadines and its coastal waters from today 6:00 p.m., Thursday, 31st December, 2020 until 6:00 pm Sunday 3rd January, 2021.
A High-Wind Advisory is issued when sustained winds of 25 to 33 knots (47 to 61km/h), not associated with a tropical cyclone, are forecast to affect the land area. Residents are strongly urged to be vigilant against falling trees limbs, loose outdoor objects and disconnected over-head wires. Residents are also advised to check roofs for loose sheeting/nails and do the necessary repairs.
A Small-Craft Warning in this case means that seas equal to or greater than 3.0 meters (10feet) and/or mean wind-speeds of 25 to 33 knots (47 to 61km/h) will affect the marine area.
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. Therefore, small-craft operators should exercise extreme caution, possibly securing their vessels by this evening. Sea-bathers are also advised to stay out of the water.
High-tide times are expected near 6:36 am Friday
7:21 am and 11:37 pm Saturday
8:09 am and 11:10 pm Sunday
This high wind advisory and small craft warning may be extended if conditions warrant.
