The Beast from the East has claimed at least 48 lives throughout Europe as the freezing conditions blast their way across the continent.
Schools are shut and weather agencies predict the brutal cold will continue as the death toll from the freezing snap rose to around 48 since last Friday, with icy conditions causing accidents and endangering vulnerable rough sleepers.
In London, a man in his sixties died after falling into the water at Danson Park in Bexleyheath while trying to save his dog.
The dog was rescued by boat, the London Ambulance Service said.
In the Netherlands, an elderly skater plunged through cracked ice in the western village of Hank.
The victims also include 18 people killed in Poland, six in the Czech Republic, five in Lithuania, four each in France and Slovakia, two each in Italy, Serbia, Romania and Slovenia and one in Spain.
Authorities are also urging people to look out for elderly relatives and neighbours after a French woman in her nineties was found frozen to death outside her retirement home in Paris, where up to 5cm of snow was expected overnight.
The Siberian cold front – dubbed the ‘Beast from the East’ in Britain, ‘Siberian bear’ by the Dutch and the ‘snow cannon’ by Swedes – has blanketed huge swathes of the region in snow and played havoc with transport networks.
Further blasts of wintery weather are expected, with authorities in Ireland and southern France among those to have issued red alerts on Wednesday.
Homeless people account for many of the dead, and cities across Europe have been racing to open emergency shelters to protect people sleeping rough.
In Germany, the National Homeless Association urged shelters to open during the day and not just at night.
‘You can die of cold during the day too,’ its chief Werena Rosenke warned.
And in the northern port of Calais, authorities were launching emergency plans to shelter migrants who camp out near the coast hoping to stow away on trucks bound for Britain.
Schools were shut across Kosovo, western Bosnia and much of Albania, as well as in parts of Britain, Italy and Portugal.
Temperatures again plunged below -20C overnight in numerous parts of Europe – even hitting -36C in Glattalp, 1,850 metres (6,000 feet) above sea level in the Swiss mountains.
Ahead of a predicted thaw towards the end of the week, both Belgium and Switzerland marked their coldest nights of the winter so far.
