Scotland and northern England are expecting up to 20cm (eight inches) of snow from today into Wednesday morning, with temperatures dropping as low as minus 15C (5F) overnight.
The central band of Scotland could be hard hit into Tuesday.
Heavy snow has already begun to affect road and air travel as the Met Office issues yellow “be aware” warnings.
A number of trains have been delayed or cancelled in Hampshire, Surrey and Kent, while passengers were left waiting for trains between Rugby, Northampton and London.
Meanwhile, flights in and out of Leeds-Bradford Airport were halted on Monday morning.
The A66 across the Pennines between Bowes, County Durham, and Stainmore, Cumbria, was also closed because of heavy snow.
