A high pressure system moving over the northwestern Atlantic and Eastern Caribbean is expected to continue affecting the coastal waters of Dominica into late Tuesday/early Wednesday and may become even more adverse at times of high tide.
The system was expected to generate surface winds of 25 – 30 knots (47 to 56km/h), and large northerly to northeasterly swells peaking between 3.5 – 4.5 metres (12 to 15ft), which were forecast to begin affecting the Eastern Caribbean on Saturday.
As a consequence, a HIGH-SURF ADVISORY and a SMALL-CRAFT WARNING has been in effect for Dominica from 12:00 p.m Saturday 27th January, 2018 through to 6:00 a.m Wednesday 31st January, 2018.
Large waves and dangerous rip-currents can be expected, which will create unsafe conditions for small-craft operators. Sea-bathers are also advised to stay out of the water.
A small-craft warning means in this case that mean wind-speeds of 25 knots (47 km/h) and 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.
Can the Met Office say why they have recently changed their easy to view satellite imagery to the difficult to view GOES-East Image Viewer?
