Fresh snowfall and gale force winds in parts of the UK are causing disruption, just weeks after severe weather led to school closures and transport problems.
More than 50 schools have closed in Northern Ireland and Scotland, and Manchester, Leeds Bradford and Belfast City airports are experiencing delays.
Snow fell overnight in Scotland, Northern Ireland and northern England, with up to 4in (10cm) on higher ground.
More snow is expected throughout the day along with 60mph to 70mph winds.
The Met Office has issued yellow warnings for snow, meaning be aware, for much of Scotland and England.
Strong winds are adding to the difficult driving conditions in affected parts of the UK. Drivers are being urged to be careful, particularly on untreated roads.
Police in Dumfries and Galloway say there has been a spate of minor accidents.
In other developments:
BBC weather forecaster Peter Gibbs said there had been quite a bit of drifting and snow storms would later turn to sleet and rain in some places. He warned of widespread ice on Tuesday night.
"However, the weather will not be as severe as a week or two ago. The snow will not settle as much at low levels," he added.
Blizzard conditions brought much of the UK to a standstill at the end of January. The cold snap was followed by widespread flooding caused by melting snow and heavy rain.
