Temperatures have plummeted to Arctic lows in much of the UK
Wintry weather has caused problems right across the UK, with schools closing, shops running low on supplies and transport services grinding to a halt.
As well as the big headlines, there have also been many tales of personal struggle, and more positive experiences of coping with - and even enjoying - the snow and ice.
Here is a round-up of some of those stories.
- The British Red Cross said it was on standby to assist pregnant women on Skye as they reached their due dates and needed to be taken to hospital.

refuse to pay their council tax for a month
in protest at the perceived lack of snow clearing.

- Another Twitter user summed up many feelings, writing: "Scotland in the snow... entrancingly beautiful, as long as you don't have to drive."
- Brian Doolan, in East Kilbride, told the BBC why he thought so many schools had closed. "I think the problem... is mostly down to the inability or lack of confidence in young female teachers to drive on snow."

She said: "I had no way of doing this, and having spent most of the morning looking after a stranger who had slid into the hedge outside my house trying to retrieve the car with the help of a local farmer, I was not about to risk life and limb to go and get it."
- Gritting was forced to stop on Londonderry's Creggan estate after

- Joseph Kent, in Woking, Surrey, wrote to the BBC about the impact of school and sixth-form closures: "One of the biggest issues is whether January examinations will be taking place.

- One man told the BBC he could see a very positive side to the snow in Birmingham: "Walking in the snow yesterday, it was very cheering to be called 'Good morning' to and have some banter with nearly everyone else on foot.

I fully support any school not opening in these conditions."
- Andrew Hetherington, from near Carlisle in Cumbria, told the BBC: "I have not seen a piece of green grass since 18 December, and we have had less than 24 hours since 12 December when the temp has risen above freezing. This is a proper winter."
