Freezing weather conditions continue to affect Britain as yellow weather warnings kick in for much of the country.
Forecasters from the Met Office brought forward a snow and ice weather warning which now starts on Monday night from 8pm and continues until 3pm on Tuesday.
They say snow is likely to be confined to hills above 100 metres over Northern Ireland and low levels elsewhere.
Between 1-3cm of snow is possible away from the coasts with up to 5cm predicted above 200 metres.
The chief forecaster said: “This warning has been updated to extend the southern boundary further south across parts of Wales for snow, and further north over Orkney to cater for the ice risk following clearance of rain or sleet here on Monday morning.
“The start time has also been brought forward to 8pm.”
The first yellow warning is an ice warning affecting the East Midlands, east and north-east England and Yorkshire and Humber.
Another snow and ice warning is in place for East of England, London and south-east England. They are both in force until 10am on Monday.
A third snow and ice warning affecting Scotland, Wales, West Midlands and Yorkshire and Humber begins at 8pm on Monday and continues until 3pm on Tuesday.
Experts say ice is expected to develop across western Scotland and Northern Ireland during this period.
Looking further ahead, a fourth yellow warning comes into play from 5am on Tuesday until 9am on Wednesday affecting the Highlands, Northern Ireland, south-west Scotland, Lothian and Borders, Strathclyde, Wales and south-west England.
Craig Snell, forecaster with the Met Office, said the whole country will be affected over the next few days.
He said: “We’ve got a weather warning which came into force from 6pm on Sunday which affects the east coast of England.
“Untreated surfaces will be prone to some ice and there could be some disruption to travel.”

Snow and ice are expected to affect the east England, London and the south east of England until 10am on Monday with rain, sleet and snow showers likely and up to 1-3cm of snow expected over the hills.
Snow is expected to fall on hills above 100 metres in Northern Ireland early on Tuesday morning.
But the warning has been extended to include Wales, West Midlands and Yorkshire and Humber from Monday night.
Mr Snell added: “It’s going to be a very cold spell across the UK and our message is to allow some extra time for your journeys.”
