On the railway, Network Rail has been working to clear heavy snowdrifts blocking lines across northern Scotland.
Multiple snowploughs have been deployed across affected lines with specialist teams working to remove snow and ice.
Rail services are now running between Inverness and Elgin, as well as Aberdeen and Dundee.
However, deep snowdrifts continue to block the Inverness-Kyle of Lochalsh line and between Elgin and Aberdeen.
