Fresh warnings have been issued over icy roads and flooding as Scotland continued to thaw out after two weeks of snow and sub-zero temperatures.
East Lothian and the Borders have been particularly hit by flooding.
There is heavy flooding on the A1 between North Berwick and Berwick on Tweed.
Central Scotland Police said parts of the M9 and M876 motorways were affected by black ice resulting in several collisions.
Tayside Police are warning of icy conditions on the M90, there have been several crashes around junction 9.
Conditions are also believed to be dangerous on parts of the A90 between Dundee and Aberdeen.
On the rail network, First Scotrail said there were line problems between Inverness and Wick, Inverness and Aberdeen, Edinburgh and North Berwick, Motherwell and Cumbernauld and Glasgow Central and Whifflet.
However, a second night of milder temperatures has led to much of the snow and ice of the past two weeks melting away.
Temperatures have risen by as much as 20C in some parts of the country - leading to floods and burst pipes.
Strathclyde Fire & Rescue attended 239 flood-related incidents on Friday and warned there could be more to come.
Glasgow City Council's arm's-length construction company City Building has responded to 702 reports of burst pipes.
It also received 1,700 gas callouts since the big thaw began two days ago and provided 1,000 temporary heaters.
Environment Minister Roseanna Cunningham said: "Warmer temperatures have led to a thaw at lower levels which is due to continue over the weekend.
"But with thaw comes the potential of flooding from the thawing of lying snow.
"The overall situation is improving and the Scottish government continues to work with key bodies across the country to ensure that disruption is minimised and critical services maintained during the period of severe winter weather."
Temperatures are expected to stay above freezing across the central belt of Scotland over the weekend, before the cold weather returns next week.
BBC One Scotland will be showing another special programme on Frozen Scotland at 1730 GMT on Sunday.
