UK weather: Snow and ice warnings remain as thaw begins
Icy roads and snow are continuing to cause disruption in parts of the the UK but forecasters say temperatures in many areas have risen.
Warnings of snow remain in Scotland and ice warnings are in place for north-east England and Northern Ireland.
Many rail services are still affected while two flood warnings are in place.
It comes as Scotland's government is considering action against employers accused of docking the wages of staff who were stranded in the snow.
Meanwhile, many rural communities in south-west England which had been cut off by poor conditions can now be reached.
People in London and the south east of England are being urged to only use water when it is "essential" after supplies were hit following the severe weather.
They urged people to take short showers rather than baths and only run washing machines and dishwashers with a full load, adding: "This will make a real difference."

Elsewhere, the villages of Lynmouth and Lynton in Devon had their water supply cut off, and roads into the village were impassable due to snow drift.
On Sunday evening Devon County Council said the roads to cut-off communities were now clear.
Across the country, the NHS said it "urgently" needs blood donors to help rebuild stocks after the bad weather led to fewer donations.
The UK's economic growth is also likely to take a short-term hit, experts have warned, predicting a "disaster" for the high street as people staying at home turned to online shopping.
Scottish Transport Minister Humza Yousaf said he had been contacted by workers who were facing disciplinary action or reduced wages for missing work - despite heeding warnings from police not to travel.
He told the BBC's Sunday Politics Scotland programme that it was not acceptable and ministers would be looking at the legal position.
Weather warnings until Tuesday
The Met Office currently has two active yellow warnings in place, covering large areas of the UK.
One, warning of snow and ice, is in place until Monday night across a large area of central and eastern Scotland.
Snow showers are expected to continue, the warning says, and there could be icy stretches on untreated surfaces.
A second warning for ice in parts of north-east England and Northern Ireland is in force until 11:00 GMT on Monday.
The Met Office has also issued a third yellow warning of snow and ice for Tuesday covering northern Scotland.
However, temperatures have been rising across England on Sunday.
Two flood warnings - which were reduced from 16 on Sunday - have been issued for coastal parts of south-west and north-east England and are because of high tides, rather than thawing snow.
But in Devon there is a lower-scale flood alert - meaning flooding is possible, rather than expected - on the rivers Clyst and Culm due to snow melt.
The Environment Agency, which had over 30 live flood alerts on Sunday, has warned of a potential surge in water levels.
On Saturday the Dawlish rail line, also in Devon, was closed as a result of flooding, but was later reopened.
Met Office forecaster Becky Mitchell said there would be a reduced risk of snow across much of southern England and Wales.
"The main point is it's gradually turning milder so we are seeing an end to widespread cold conditions from this weekend onwards."
