Britain's big freeze begins: Fresh weather warnings in place as lows of -12C possible across UK

A yellow warning of snow and ice which covered the country as far south as Perth until the end of Monday has now been extended until midnight on Tuesday.

The Met Office has also issued a yellow warning of snow and ice for the country from the central belt southwards down beyond the border which is valid until 11am on January 6.

On Tuesday forecasters predict that a further 2-5cm of snow is likely to fall fairly widely, with the possibility of a further 10-15cm in some areas.

From the central belt southwards forecasters predict an area of "mainly light snow" with most places likely to see no more than 1-2cm.

Pupils are enjoying an unexpected extra day of holiday at schools in Shetland, Orkney, the Western Isles and Aberdeenshire while dozens in Moray are also shut as a result of the weather conditions.

In Aberdeen city, dozens of schools were closed for the day after opening was initially delayed until 11am.

The weather has disrupted rail travel with the Inverness to Wick/Thurso, Inverness to Kyle, Inverness to Aberdeen and Aberdeen to Dundee lines shut after heavy snow drifts on the tracks.

Network Rail Scotland said that multiple snowploughs have been deployed across the affected lines, where specialist teams are working to remove snow and ice from key routes and restore services.

Gary Hopkirk, route programme director at Network Rail Scotland, said: "Deep snow can pose a serious risk to the railway, and when snow depth exceeds 30cm, trains can't run safely unless fitted with snow ploughs.

"Our teams are working as hard as they can, however, in some parts the snowdrifts are forming as quickly as we're clearing them.

"We'll only reopen lines and return to normal operations once we're confident it's safe to do so. We appreciate the patience of passengers while we manage the impact of this heavy snowfall."

Mark Ilderton, ScotRail said the majority of the ScotRail network remains open despite the "challenging" weather conditions in the north of the country.

He said: "The Met Office yellow weather warning for snow and ice has been extended until Tuesday, 6 January, covering the entire country.

"Conditions can change quickly, so we'd encourage customers to plan ahead and check their journey before travelling."

Some flights have also been disrupted by the weather conditions.

Loganair cancelled flights from Aberdeen and Inverness airports following heavy snowfall, while a number of flights to and from Sumburgh Airport in Shetland were cancelled as were several departures from Kirkwall Airport in Orkney.

A Highlands and Islands Airports Limited (HIAL) spokesman said: "Forecasted adverse weather may impact flight schedules across Scotland. Please contact your airline for the latest flight information before travelling."

The A90 was closed between Goval and Craibstone at Bogenjoss because of weather conditions, while snow gates were closed on the A939 between Cock Bridge and Tomintoul.

Meanwhile the A9 south of Berridale will be shut from 9am to 11am on Tuesday so a Royal Mail lorry can be recovered, after

Infrastructure firm Amey said all 27 trunk routes in the south west of the country will receive "double salt treatments" at 1pm and 1am throughout most of the week, while all 15 patrol gritters will remain on the network continuously.

In the yellow alert area, forecasters predict that Grampian, the north-west Highlands and Aberdeenshire will see the most frequent snow showers on Monday, with 5-10cm likely to fall fairly widely and a few places seeing 20-30cm.

A Met Office amber warning of heavy snow showers covering Shetland, Orkney and parts of the Highlands and Aberdeenshire expired at 10am on Monday.

Assistant Chief Constable Alan Waddell, of Police Scotland, said: "The forecasted heavy snow showers and ice means driving conditions are likely to be hazardous in some areas.

"Our advice is to plan ahead and consider if your journey is really necessary during the weather warnings.

"We continue to work with partners to help our communities impacted by the adverse weather.

"If you need to travel, please drive to the conditions, be prepared for delays and allow extra time for your journey.

"Please don't drive through road closures, the decision to close roads is not taken lightly and is done for public safety."

Ministers met with police, local authorities, utilities companies and other bodies on Monday to discuss efforts to recover from the current snowfall and to prepare for further snow and ice warnings.

Following the meeting, John Swinney said snowfall across northern Scotland has had a "significant" impact and that a "huge effort" was going into keeping transport moving and public services open.

"At present, there is still some travel disruption but trunk roads are open and rail, ferry and air services are working to get back to normal as quickly as possible," he said.

"Likewise, many schools are closed today but remote learning is in place for young people while contingency plans are in place for affected health and social care services.

"There will be further snow and ice, with yellow warnings in large parts of Scotland and temperatures set to remain cold, so impacts will continue to be felt in the coming days which could include transport problems and I would encourage everyone to plan ahead, look out for each other and pay close attention to the range of weather and travel advice available."

He also paid tribute to the "truly exceptional" efforts of farmers, volunteers and members of the public in helping clear roads, dig out cars and keep people safe, which he said showed "heartening" community spirit.

He added that ministers will continue to keep the situation "under review".

Police travel advice has been issued following a further amber weather warning for snow across north and north-east Scotland.

Assistant Chief Constable Alan Waddell: "The forecasted heavy snow showers and ice means driving conditions are likely to be hazardous in some areas.

"Our advice is to plan ahead and consider if your journey is really necessary during the weather warnings.

"We continue to work with partners to help our communities impacted by the adverse weather.

"If you need to travel, please drive to the conditions, be prepared for delays and allow extra time for your journey.

Loganair cancelled flights from Aberdeen and Inverness airports following heavy snowfall.

Liverpool John Lennon Airport posted on X on Monday at 8am to say the runway was closed due to wintry conditions and some flights were "subject to delay and there have been some cancellations".

A spokesperson for Aberdeen City Council said schools and ELC provisions in the city will not open until 11am on Monday and breakfast clubs will not run.

Scottish Transport Secretary Fiona Hyslop said: "We've already seen challenging conditions and freezing temperatures, with more snow and ice on the way for the same areas.

"Of course for many, Monday marks a return to work from the festive break. If you have to travel then please ensure your vehicle is winter-ready and have a winter kit in your car.

"Follow Police Scotland travel advice. If you can delay your journey until the amber warning has expired, please do so.

"I'd also like to thank all the frontline staff such as gritter drivers, chainsaw gangs, police officers and many others who have been out working in dreadful conditions these past few days and over the next 48 hours."

The amber warning expires at 10am on Monday and covers Aberdeen, Aviemore in the Cairngorms, and Ullapool, Ross-shire.

The warnings cover much of the Highlands and Aberdeenshire areas, Orkney, Shetland, and Outer Hebridean Islands, from Sunday evening until 10am on Monday - with the potential for another 5-10cm of snow accumulating at low levels, with the potential for 20-30cm on high ground.

Separate yellow warnings for snow and ice cover much of the UK, including Northern Ireland, Wales, much of Scotland north of Glasgow, south-west England, north-west England, the Midlands, east England and the north-east of England, stretching up to the Scottish Borders.

Amber weather warnings are issued when there is an increased likelihood of impacts from severe weather, including the possibility of travel delays, road and rail closures, power cuts and the potential risk to life and property.

Yellow warnings are issued for a range of weather situations, including when it is likely that the weather will cause some low-level impacts, including some disruption to travel in a few places, or when the weather could bring much more severe effects on the majority of people, but the certainty of those impacts occurring is much lower, according to the Met Office.

The UK Health Security Agency (UKHSA) has issued amber cold health alerts for England as an early warning that adverse temperatures are likely to affect health and wellbeing, running until Friday.
