The Met Office has issued a severe warning for wind across wide areas of the north of Scotland.
Showers will turn wintry this evening across the warning area, with the risk of a more prolonged spell of snowfall late in the night and early Wednesday morning, especially in the south.
This will give a covering of snow with 2-5 cm possible in many places and locally 5-10 cm, these higher accumulations mainly above 100 m. Icy stretches on untreated roads and pavements are also likely to form.
A Met Office statement said: “Please be aware of some difficult driving conditions and the potential for travel disruption into the Wednesday morning rush hour.
“A cold front will move east and south across the United Kingdom through Tuesday night and Wednesday morning.
“This will introduce significantly colder air with frequent showers these turning readily to sleet and snow even at low levels. 2 to 5 cm is expected in many areas by dawn Wednesday with up to 10 cm in places.
“These higher accumulations are more likely over higher ground above 100 m but may also occur to low levels where showers are heavy and prolonged. Clear spells between showers will also lead to icy stretches forming on untreated surfaces.”
