Snow and ice alerts issued across Scotland as temperatures drop
'The public should be aware of potential for increased iciness and possible disruption to travel.'
Drivers were warned to take care on the roads as the Met Office issued snow and ice alerts covering all of Scotland on Tuesday evening.
Sleet and snow showers are expected to accompany a cold airmass which will move southwards on Tuesday evening through Orkney and Shetland, the Highlands, Grampian, Tayside, Fife, Central, Lothian and the Borders and southwest Scotland.
Some of the showers are forecast to be "on the heavy side", with five to ten centimetres of snow likely to accumulate over hills and on higher routes.
Icy stretches are also likely, especially on untreated surfaces at lower levels.
The Yellow weather warning extends until 3pm on Wednesday as does another warning for ice in the Highlands, Strathclyde, Central Scotland, Tayside, Fife, Lothian and the Borders are southwest Scotland.
A spokesman for the Met Office said: "Icy stretches are also likely, especially on untreated surfaces at lower levels.
"Outbreaks of rain and sleet will be clearing southwards on Tuesday night and early Wednesday, leaving surfaces wet and prone to freezing as skies clear and temperatures fall.
"The public should be aware of the potential for increased iciness, especially early on Wednesday, and possible disruption to travel."
The warnings come after two bad accidents on Scotland's roads on Tuesday.
In Dumfries and Galloway a man was airlifted to hospital after a crash involving a livestock carrier and a car. The collision happened at around 7.20am on the B723 at Longmoor near Hoddom.
In another crash in Bathgate, in West Lothian, a man had to be cut free and taken to hospital. He was treated for minor injuries after the crash at around 6.10am.
STV weatherman Sean Batty warned that more wintry weather is on the way. He said: "Very wintry weather can be expected by the end of the week with a band of rain, sleet and snow spreading in from the west on Thursday.
"Much of this will fall as snow, especially on high levels where significant levels of snow can be expected."
