Richard Brown, Head of Hydrology for the Scottish Environment Protection Agency (SEPA), said:
Exceptionally strong winds and tidal surge in the Atlantic continues to produce unusually high tides and large waves along the north and west coast of Scotland.
“The greatest risk of coastal flooding is expected today (Wednesday 10 December), especially along the coastlines of Caithness, Sutherland, the Western Isles, Orkney and Shetland Isles, as strong to gale force winds create very large waves and tidal surges which could result in localised flooding to roads, coastal pathways, causeways and individual properties from spray and wave overtopping. There may also be lesser impacts affecting Argyll and Bute, Firth of Clyde, Clyde estuary and Dumfries and Galloway.
“The effects of the storm are expected to subside slowly but continue overnight into Thursday and Friday this week with a risk of flooding from wave overtopping and spray, before conditions start to ease substantially over the weekend.
“The Moray coast and Eastern stretches of coastline may also experience smaller surges and isolated instances of localised flooding due to high tides.
“We would strongly encourage people to remain vigilant and be mindful of the conditions in their locality and when travelling, especially along more exposed coastal areas. Members of the public can access the latest flood updates for their area via our website, and sign up to the Floodline direct warning service by calling 0345 988 1188.”
