Although the gales and squally, wintry showers are now beginning to ease, please be aware of the likelihood of some ice forming through the evening as temperatures fall, says the UK Met Office.
And the Loganair service from Edinburgh to Stornoway was predicted to be almost three hours three hours late this afternoon/evening.
But Shetland was worst hit. At 15:30, the airline have decided to cancel operations to Sumburgh for the rest of today as exceptionally strong winds caused damage to the construction works to upgrade the terminal building. The risk of further damage in continuing high winds is present and so for safety reasons, Loganair have cancelled flights to and from Edinburgh and Aberdeen.
Contingency plans to offer additional seats on tomorrow’s flights on the affected routes are being put in place now. Strong winds also led to the cancellation of today’s service between Glasgow and Barra. An extra flight will operate in each direction on this route tomorrow.
For all other services, aircraft captains will assess the weather conditions before each flight and make the final decision as to whether the flight can take place.
In view of the high probability of travel disruption, Loganair have extended their rebooking policy to offer you additional peace of mind around your travel plans. If you hold a reservation to travel on 26 December yet wish to travel later, you can now change your booking to any flight with available seats within the next seven days.
Tomorrow (Tuesday 27 December) they expect to operate their full planned schedule of flights. Delays on early services to and from Sumburgh are possible subject to requirements to inspect and secure construction materials around the terminal building.
Meanwhile services across CalMac's network were today (Monday December 26), beginning to resume after a very difficult weekend of festive weather, though some disruption remains, particularly on routes from Oban. High winds and rough sea states persist in many areas, but forecasts indicate that conditions may improve later.
The current period of bad weather looks likely to subside later today and into tomorrow (December 27) and it is hoped that Tuesday will bring with it a greater degree of certainty for passengers and a further increase in the number of routes returning to full service. "Thankfully conditions do appear to be improving and we are continuously monitoring each route," said CalMac's operations director Drew Collier. "There is no doubt this has been a difficult weekend for our communities, customers, crews and port staff, and we can hopefully look forward to a period of increased certainty for travellers.
"I remain appreciative of the support and forbearance we have experienced in light of these conditions, which are out of our control but, nonetheless, frustrating."
Further very strong winds, associated with Storm Conor, continued through much of Boxing Day (Monday). Gusts of 50 to 60 mph were likely to occur quite widely, locally up to 70 mph. These stronger gusts are likely to be more frequent over the far north of Scotland, where there is a risk of gusts of up to 80 mph. Winds were easing from west to east through the afternoon and evening. Frequent wintry showers will be an additional hazard across northern Scotland, the Met Office warned.
