Parts of the UK woke up to snow on Friday morning as forecasters warned up to 20cm (8in) could fall in some regions.
Temperatures plunged across the UK as Storm Caroline brought winds of up to 90mph to northern Scotland and left an Arctic air flow in its wake.
About 8cm of snow had already fallen in Aviemore, in the Scottish Highlands, by dawn on Friday, while parts of Northern Ireland, Wales and areas to the west of the Pennines had also seen a covering.
Forecasters said snow was likely to become more widespread throughout the day, and a yellow weather warning was in place for ice and snow across much of Scotland, Northern Ireland, Wales and parts of northern and western England.

Met Office meteorologist John West said: “We saw a fairly consistent stream of snow showers overnight, and there will be a constant feed throughout the day and into Friday.
“We could see some fairly significant accumulations. Broadly speaking we're looking at 2cm to 5cm, but in more exposed areas we could see 10cm to 20cm.
“It will also be bitterly cold, with highs of 2C or 3C outside those snow showers. But the wind chill is going to make it feel sub-zero.”
