Sweden has recorded its coldest January night in 25 years, with a reading of -43.6C in the far north as a cold snap hit the Nordics.
"To put that into perspective, that is the lowest January temperature in Sweden since 1999," Mattias Lind, meteorologist at Sweden's national weather agency SMHI, said
In January 1999, a temperature of -49C was recorded in Sweden, which tied the record set in 1951.
Mr Lind said that today's measurement was made at the Kvikkjokk-Arrenjarka station in Sweden's far north.
"It is the lowest temperature that has been recorded in this specific spot since measurements began" in 1888, he said.
Several other stations recorded temperatures of below - 40C in Sweden's north.
While residents of the region are used to seeing freezing temperatures, the recent cold snap has forced local bus operators to suspend services.
Train operator Vy said yesterday that it had cancelled all trains north of the city of Umea for several days.
Trains were also disrupted in neighbouring Finland, where a seasonal record of -38.7C was recorded yesterday evening in the northern Lapland region.
Several instances of frozen or burst water pipes were also reported, and Finnish broadcaster YLE said around 300 people in the city of Tampere were left without running water.
The cold front is expected to move south over the next few days, with the Finnish capital Helsinki already seeing temperatures falling to -15C today.
But despite colder temperatures being expected tomorrow, some of the capital's residents were unfazed by the prospect.
"I'm really loving it. It's a mindset thing I guess," Katja, a woman in Helsinki, said.
"It's all about the clothing," she said, wearing a thick black winter jacket with the hood pulled over her head.
"Yeah, just a lot of clothes and the attitude ... it's going to be cold but it's beautiful," her friend Nita agreed as snow fell.
The extreme cold is also expected to hit Norway towards the end of the week, with temperatures in Oslo potentially falling to -27C this weekend, according to the national weather service.
Heavy snowfall has already affected the south of the country with school closures and cancelled flights.
Meanwhile, the Danish Meteorological Institute said there was a risk of snowy and icy roads in large parts of the country as it issued an orange warning - its second highest - for heavy rain in the south, which is battling flooding.
Further south, parts of Germany - where the weather has been mild and wet - are dealing with flooding, which could be aggravated by further rain in the worst-affected north-western state of Lower Saxony.
In the Netherlands, police near the southern city of Eindhoven said that strong winds may have played a role in the death of a 75-year-old man who fell off his bike yesterday as high winds lashed much of the country.
