Many areas of Britain faced frosty and icy conditions this morning ahead of the arrival of Storm Bert tomorrow.
The Met Office said it expects the storm to bring "heavy rain, strong winds and disruptive snow to parts of the UK through the weekend" and potentially cause travel disruption and flooding.
Much of the UK experienced temperatures close to freezing last night, the Met Office said, with -6C (21.2F) recorded at Tulloch Bridge in Scotland.

Several yellow warnings for snow and ice were in place across the UK until 10am on Friday, while one covering parts of Scotland will remain in place until midday.
They came ahead of an amber warning for heavy snow and ice in place between 7am and 5pm on Saturday in central parts of Scotland.
The Met Office said 10-20cm of snow was likely on ground above 200m and there could be as much as 20-40cm on hills above 400m.
Several other yellow alerts for wind, rain and snow will also cover much of the UK.

Met Office meteorologist Honor Criswick said: "Through into Friday... snow showers are set to continue mainly around coastal areas though once again still a few feeding inland at times.
"There will also still be plenty of autumnal sunshine. Still feeling cold though, particularly in those brisk winds - once again we're only looking at highs of around 5C, slightly higher in the southwest around 7C.
"Across the north those temperatures struggling to move past 2-3C.
"As we head into Friday evening, a change is on its way as we introduce Storm Bert moving its way in from the Atlantic. So we'll see clouds spilling in from the southwest with outbreaks of rain - heavy at times by the time we reach Saturday morning."
"Heavy" outbreaks of rain are likely throughout Saturday, "falling as snow" at times across parts of England and Scotland, Ms Criswick said.
More than 114 schools were shut in the Highland Council area on Thursday because of snow, almost 40 were shut in Aberdeenshire and 12 were closed in Moray.
In England, 89 schools were shut in Devon, 60 in Cornwall and 18 in Dorset, while in Wales 18 were closed in Denbighshire, 10 in Conwy and two in Wrexham.
