An Arctic airmass remains locked over Scotland, bringing prolonged cold conditions, heavy snowfall, drifting snow and widespread ice across the Highlands and much of the north.
The whole of Scotland remains under Yellow warnings for snow and ice, with the Met Office warning that further disruption is likely through Monday and Tuesday.
Some of the most severe conditions have been recorded in Highland and rural areas, with 52cm of snow measured at Tomintoul in Banffshire and 34cm at Loch Glascarnoch in Ross and Cromarty by Monday morning.
Temperatures have remained well below freezing, with overnight lows expected to fall to as low as minus 12°C in areas with lying snow.
While some inland areas may see dry and sunny spells, snow showers are continuing across northern and eastern parts of Scotland, easing at times but still posing risks on untreated roads and footpaths.
The Met Office has warned there is potential for a further spell of disruptive snow affecting central and northern Scotland later on Tuesday, alongside the ongoing risk of ice.
Matthew Lehnert said winter hazards are likely to persist.
“The UK will continue to experience a range of winter weather hazards this week, with low temperatures, snow showers and the risk of ice for many.
“Warnings are likely to be updated, so it is important to keep up to date with the forecast.”
Local authorities across the Highlands and north east are working around the clock to respond.
Highland Council confirmed its teams are prioritising primary routes across the region, warning that drifting snow and rapidly changing conditions mean journeys should only be made if essential.
Significant disruption has been reported across Sutherland, Caithness, Ross and Cromarty, Lochaber, Skye and Badenoch and Strathspey, with some routes closed and others passable only with care.
Moray Council said gritter drivers have been working extended shifts since before Hogmanay to keep key routes open, while urging residents to avoid unnecessary travel.
Schools across parts of the Highlands and Moray have moved to remote learning or delayed reopening, with councils advising parents to check local service status portals for updates.
Public transport disruption remains likely, with bus and rail services under review and travellers advised to check operator updates before setting out.
Looking further ahead, the Met Office has warned that a low pressure system later in the week could bring a mix of strong winds, heavy rain and further snow, depending on its track.
Mike Silverstone said confidence will improve as the week progresses.
“The exact position of the low pressure system will determine whether areas see heavy rain, strong winds or further snow, so staying informed is essential.”
Advice has also been issued for people to look out for vulnerable neighbours during the cold spell.
Age Scotland urged people to check older residents have food, medication and warm spaces, and to help clear paths safely where possible.
Authorities continue to stress that conditions can change rapidly and that caution, patience and preparation remain vital as winter weather tightens its grip on the Highlands.
