Where have the deaths been?
In Poland, most of the victims were rough sleepers.
The deaths are partially attributed to a combination of the severe cold and alcohol consumption by homeless people, who drink hoping to warm up, the BBC's Warsaw correspondent Adam Easton reports.
When the night time temperature is -15C (5F), as it has been all week in the Polish capital, this is a deadly combination, our correspondent adds.
Over the past week, the cold weather has killed seven in Slovakia, six in the Czech Republic, five each in Lithuania and France (excluding the avalanche victims) and at least three in Spain, according to AFP.
Italy, Romania, Serbia and Slovenia have all counted two deaths each, while one person has died in Britain. The Netherlands, Sweden, and Norway each also recorded one weather-related death.
In Spain, one of the three victims was a homeless man who had been sleeping in an abandoned truck.
In France, another homeless man died in an abandoned home in Lens of smoke inhalation after lighting a fire to stay warm, AFP said.

The northeast of Europe is expected to remain cold, however – and relatively cold weather is likely to continue in parts of the UK and Ireland. (BBC)
