Analysis indicates that a High Pressure System moving over the northwestern Atlantic will generate surface winds of 20 – 25 knots (37 to 47.km/h), and large northerly to northeasterly swells peaking between 3.0 – 4.0 meters (10 to 13ft), which could begin affecting the eastern Caribbean late tomorrow, Saturday 27th January, 2018.
Wind speeds are expected to gradually increase on Saturday with fresh breeze 16 – 21kts (29-38km/h) and possible strong/high wind gusts reaching 25-30kts (46 – 56km/h) Sunday and Monday.
Swells across St. Vincent and the Grenadines are expected to start increasing Saturday, reaching 2.5m on the east coasts with north-north easterly swells by early Sunday morning. Marine conditions are expected to deteriorate Sunday night with moderate to rough swells (2.5 – 4.0m).
As a consequence, a HIGH-SURF ADVISORY and SMALL-CRAFT WARNING will be in effect for St. Vincent and the Grenadines from 6:00 pm Saturday 27th January, 2018 until 6:00 am Wednesday 31st January, 2018.
Large waves and dangerous rip-currents could create unsafe conditions for small-craft operators, becoming even more adverse at times of high tide. High tide times are expected Sunday 2:11 am and 2:49 pm
Monday 3:01 am and 4:05 pm
Tuesday 3:54 am and 5:26 pm
The Small-Craft Warning means in this case that winds of 20 – 25 knots or greater and seas equal to or greater than 3 meters (10ft) are forecast to affect our marine area.
The High-Surf Advisory means that breaking wave action could pose a threat to life and property within the surf zone.
Sea bathers and other users of the sea are advised to stay out of the water during the these times. Conditions should start improving by late Tuesday/early Wednesday.
The High-Surf Advisory and Small-Craft Warning remain in effect for St.Vincent and the Grenadines until 6:00 am Wednesday 31st January 2018.
The St.Vincent and the Grenadines Meteorological Service continues to monitor, and will update as necessary.
