Heavy snowfall and deadly blizzards lashed Europe on Thursday with temperatures dipping below minus 10 degrees.
Heavy snowfall and deadly blizzards lashed Europe Thursday, forcing Geneva's busy airport to close, as the region shivered in a deep freeze that has gripped countries from the far north to Mediterranean beaches in the south.
The snowstorms, unusual for much of Europe at this time of year, left roads blocked, thousands of drivers stranded and schools shut, with weather agencies predicting the biting cold would continue in parts of the region at least through Thursday evening.
The death toll continued to mount, as another three people perished in Poland, taking the number of victims there to 21, most of them rough sleepers.
There have also been six deaths in the Czech Republic in recent days, five in Lithuania, four each in France and Slovakia, three in Spain, two each in Italy, Serbia, Romania and Slovenia, and one each in Britain and the Netherlands.
One of the Spanish victims was a 39-year-old homeless man who had been sleeping in an abandoned truck.
"Those most at risk of cold-related illness include elderly people, children, and people who have chronic diseases or physical or mental limitations," the World Health Organization said in a statement, adding that the poor, the homeless and migrants were often hardest hit.
The Siberian cold front -- dubbed the "Beast from the East" in Britain, "Siberian bear" by the Dutch and the "snow cannon" by Swedes -- on Thursday forced Geneva airport to announce it was shut until further notice. (AFP)
Switzerland has in recent days seen temperatures plunge to nearly minus 40 degrees Celsius (minus 38 Fahrenheit) at higher altitudes.
In Britain, Storm Emma, rolling in from the Atlantic, looked poised to meet the Siberian chill, causing further snowfall and bitterly cold temperatures.
A red alert was extended Thursday for southwestern England, southern Wales and Scotland -- meaning extreme weather, a risk to life, widespread damage and transport disruptions -- with wind and snow expected through the night. (AFP)
In Edinburgh, all schools were closed, as police advised people not to travel "unless you're an emergency worker".
Glasgow airport remained shut, as Gatwick in London expected "a large number of cancellations and delays to flights today".
"This is a very difficult situation but everything possible is being done," Scottish leader Nicola Sturgeon said on Twitter.
The mercury also dropped below freezing across southern Europe.
Snowfall in northern Italy forced the cancellation of 50 percent of regional trains, while in the city of Naples, schools were shut.
In normally-balmy southern France, beaches in Nice were blanketed in a thick layer of snow.
Near the city of Montpellier, around 2,000 drivers were stranded on a motorway, causing anger from those sitting behind the wheel for hours on end.
"The motorway looks like a cemetery of trucks and cars," tweeted Anthony Jammot, describing an "apocalyptic" 24 hours in his car with two young children and no information or help from local authorities.
In Paris, which awoke Thursday under a blanket of snow, authorities continued operating emergency shelters for the city's roughly 3,000 homeless.
Demanding more efforts to keep people off the streets, around 30 local officials spent the night near the city's Gare d'Austerlitz train station as temperatures dipped below zero.
"We can't keep considering the homeless just another part of the scenery," Greens lawmaker Ali Id Elouali said.
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.
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. (AFP)
Europe's cold snap comes as the Arctic experiences record-high temperatures, prompting scientists to ask if global warming may be playing a role in turning things upside down.
The unusually cold weather has also impacted local customs, as the first spring month began.
In Romania, people were marking the day without the amulets they traditionally exchange.
In the capital Bucharest, where it has been snowing since Monday and where temperatures have been hovering around minus 10 degrees Celsius, sales of the "martisor" good luck charms have plummeted along with the temperature.
Florists have also suffered, as the amulet is often given with a bunch of flowers.
"The 1st of March is the most important day of the year for us, where we sell the most flowers," florists' association president Adrian Dinca told AFP.
