Much of the UK has woken up to snow after blizzard conditions blanketed much of the north of England and Scotland as well as parts of Wales in a coating of Arctic conditions.
And forecasters are warning of the risk to life, power supplies and travel disruption following the heavy snow overnight and into this morning.
An amber alert for snow means there is “potential risk to life and property” and the Met Office has issued such an alert for the north of England including Yorkshire as well as much of Scotland.
Meanwhile another yellow warning for snow has been issued across most of the UK, with rain warnings for potential flooding further south.
The Met Office has issued an amber warning for snow and ice for parts of Scotland and northern England, with a “good chance some rural communities could be cut off”.
Amber warnings mean there is the potential for risk to life and property.

Met Office meteorologist Craig Snell said the effects of the storm would continue throughout the weekend.
“We expect the worst of the snow to pass by 12pm in Yorkshire but there will be some heavy rain and travelling conditions throughout the day will be pretty poor,” he said.
He told the PA news agency there was 13cm of snow measured in Leek in Staffordshire on Saturday morning and 68mph winds in Brixham, Devon.
“As milder weather comes in snow will melt, leading to pretty hazardous conditions,” Mr Snell said.
