Swathes of the UK are under snow, rain and ice warnings causes travel chaos and threatens to bring further misery to towns ravaged by flooding.
Motorists became stranded and there were a number of crashes as snow, sleet and rain led to hazardous driving conditions across England and Wales during Thursday morning's commute.
In Wales, police closed roads that became "impassable" because they were buried under so much snow in places that looked like a winter wonderland after temperatures plunged overnight.
The Met Office has issued snow warnings for South Wales, parts of southern England and the West Midlands, as half a month's worth of rain in a single day threatens to flood more homes in Yorkshire and the Midlands.

A separate rain warning is in place across South Wales and much of southern England.
The Environment Agency (EA) warned that Britain's flooding was far from over and told residents of flood-hit areas in South Yorkshire and Lincolnshire to remain vigilant.
It had issued 30 flood warnings (meaning "immediate action required) - many of them in Yorkshire and the Midlands - as of Thursday morning, in addition to 125 alerts (meaning "be prepared) scattered across England.
Some places saw their first flurries of the season on Wednesday night and Thursday morning as snow hit South Wales and South West England.
In Wales, cars got stuck in snow on the A482 at Lampeter and at least two roads - the A4109 at Seven Sisters and the A4221 between Abercrave and Coelbren in Powys - were shut because they were "impassable", WalesOnline reports.
Drivers faced hazardous driving conditions on routes on high ground in Wales, where there were also eight flood alerts.
Tricky driving conditions were also posing problems for commuters in South West England, including Gloucestershire.
A number of schools were closed or forced to open late due to inclement weather.
St. Andrews Church of England Primary School in Wotton-under-Edge, Gloucestershire, said it would open late "to allow the roads to settle" after overnight snowfall.
In Herefordshire, Peterchurch Primary School said it was closed due to flooding, and Stoke Prior Primary School, on the outskirts of Leominster, said it was shut because “many of our staff are unable to make it through flooded roads”.
Temperatures plummeted to -4C in parts of Scotland overnight, when an ice weather warning was in force across the country.
Met Office meteorologist Luke Miall said "the worst of the winter weather has now moved through" the South West, but "it's the same one that's going to push its way north and will affect the flooded areas from last week".
Swollen rivers are at risk of rising again, putting more homes and businesses in danger of being swamped by floodwater.
Kate Marks, the Environment Agency's (EA) flood duty manager, said: "Heavy rain is expected on Thursday, Friday and over the weekend which could lead to further flooding for communities in South Yorkshire around the Lower River Don.
"Parts of Lincolnshire and the Midlands could also be affected by rain falling on already saturated ground over Thursday and Friday, as well as other parts of England as rain crosses the country from west to east.
"It's really important that impacted communities remain vigilant and take steps to prepare for flooding by checking their flood risk regularly and making plans to stay safe."
The EA said 300 staff were working around the clock in various parts of the country, deploying pumps to disperse water through five of the worst-hit locations.
Since flooding began on November 7, around 14,400 properties had been protected by flood defences, including 5,000 in South Yorkshire, the EA said.
The Government's response to the flooding has spilled over into an election issue, with Prime Minister Boris Johnson facing heavy criticism during a visit to affected areas in South Yorkshire on Wednesday.
The PM later paid a visit to the badly-hit village of Fishlake, where he told reporters: "We will get people back on their feet."
On Tuesday, Mr Johnson announced that relief funding would be made available for those affected by the floods and said funding for local councils to help affected households would be made available to the tune of £500 per eligible household.
The Met Office snow warning for today affects parts of Wales and central England.
It predicts: "A mix of rain and sleet at lower levels, but snow falling at elevations above 200m, with some snow settling on roads above 250-300m. A few cm is possible on the highest routes."
The areas which could see snow in Wales include: Blaenau Gwent, Caerphilly, Carmarthenshire, Ceredigion, Merthyr Tydfil, Monmouthshire, Neath Port Talbot, Powys, Rhondda Cynon Taf, Swansea, Torfaen.
In England: Herefordshire, Worcestershire Shropshire, Bath, Somerset, Gloucestershire, Swindon, Oxfordshire, west Berkshire and Wiltshire can expect flurries.
try above 200m away from the coast across Aberdeenshire and Moray, with 1-2cm of snow possible."
Today's Met Office ice warning for Scotland states: "Scattered showers will affect much of the east coast of Scotland this evening and overnight, falling onto freezing surfaces.
"These will be heavy at times and will lead to a risk of icy surfaces where any treatment is washed off.
"Showers will be win
Two rain warnings are also in force in the UK today, one in north-east England and another larger alert covering south Wales and the south, south-east, south-west and centre of England.
Both warn of 'danger to life flooding', with the larger alert also predicting up to 60mm of rain in some places, which is equivalent to half a month's worth of showers.
Another Met Office alert has been issued for parts of the Midlands and north-east England tomorrow, warning of 'danger to life' flooding.
