Britain weathered the coldest night of the year as numerous areas in the country fell below freezing.
Clear skies overnight resulted in a major temperature drop to below -12.4C (9.6F), with a new low recorded in Shawbury in Shropshire.
Large areas of the country – including London, the Midlands, Northern Ireland and Wales – are subject to a yellow weather warning for snow and ice until 11:00am on Tuesday.
Meanwhile, dozens of schools in the West Midlands, Wales, and the South West will remain closed for a second day after the cold conditions.
Tuesday morning will also bring freezing fog patches, with rain and snow expected later in the day.
Craig Snell, a meteorologist for the Met Office, told the Press Association there was risk of further problems caused by rain falling in icy areas and the snow would take a few good days to melt away.
