A yellow weather warning for snow and ice has been issued for large parts of the Highlands and Islands as frequent and heavy snow showers are forecast to continue through the weekend.
The warning, issued by Met Office, runs from 12am on Saturday 3 January until 11.59pm on Sunday 4 January and covers Highland, Na h-Eileanan Siar, Orkney and Shetland.
Forecasters warn that strong northerly winds will drive snow showers well inland, with conditions remaining cold enough to prevent any meaningful thaw of lying snow.
Further accumulations of between 2cm and 5cm are expected at lower levels, with localised totals of 10cm to 15cm possible in places.
Above 200 metres, particularly across the northwest Highlands and higher ground, accumulations of 15cm to 30cm are possible, with drifting snow and temporary blizzard conditions likely at times.
Temperatures inland are expected to stay below freezing throughout the weekend, increasing the risk of ice on untreated roads, pavements and cycle paths.
Travel disruption is likely, with possible delays on roads, rail services and flights, while some rural and island communities could become temporarily cut off.
There is also a risk of power outages and disruption to mobile phone coverage in exposed areas, alongside an increased risk of slips and falls.
Lightning has also been highlighted as an additional hazard near heavier snow showers, particularly in coastal areas.
Drivers are being urged to plan journeys carefully, allow extra time, and carry essential supplies including warm clothing, food, water, torches, phone chargers and de-icing equipment.
Residents are also advised to prepare for possible power cuts by gathering torches, batteries and backup charging packs, particularly in remote areas.
The Met Office has stressed that weather warnings may change quickly and people should continue to check local forecasts and updates as conditions develop.
