Motorists in Scotland have been urged to exercise caution following a return of heavy snowfall in the north of the country.
Drivers on Orkney and Shetland woke up to fresh snow and treacherous road conditions as Britain's big freeze continues to cling on into February.
Weather warnings have been issued for drivers in Caithness, where minor roads were "badly affected" by snow and ice, police said.
Elsewhere, the A9 Inverness to Wick road and the A93 at Glenshee were closed after heavy snow brought traffic to a halt.
Drivers in the south west of the country have also been warned of a new band of snow that is moving in across from Northern Ireland, bringing with it the prospect of further travel disruption as temperatures continue to plummet.
Julian Mayes, a forecaster for MeteoGroup, the weather forecasting arm of the Press Association, said: "Scotland is heralding the arrival of less cold weather.
"Towards the end of the week, it will be less cold than previously, and relatively dry and cloudy."
