The toll from Europe's killer cold snap hit at least 360 on Monday with nine new victims found in Poland, most of them homeless, and five drowned when a Bulgarian dam burst after torrential rain.
The rain and snowstorms lashing southern Bulgaria collapsed the dam early Monday, submerging the small village of Biser under 2.5 metres (eight feet) of water, emergency services said.
Biser mayor Zlatka Valkova told state news agency BTA three elderly men had drowned in their homes and a massive rescue effort was under way in the village of about 800 people. National radio reported two other people were killed when their car was swept off a bridge.
"People are in panic," regional mayor Mihail Liskov said on national radio. "Ninety percent of the village is under water."
Two larger dams in southern Bulgaria risked spilling over and residents were told to prepare to evacuate. Heavy rains also triggered a landslide that derailed a train near the Turkish border. No injuries were reported.
Meanwhile, temperatures in Poland plunged to as low as minus 24 degrees Celsius (minus 11 Fahrenheit), bringing another deadly night for the homeless.
As has been the case throughout the 10-day-old cold snap, transients have borne the brunt of the suffering, with frozen victims found in abandoned and unheated homes, fire escapes or makeshift shelters on Europe's streets.
In a bid to save lives, Poland's homeless shelters have dropped a ban on drunken individuals.
Monika Golebiewska, a Warsaw police officer whose beat is a daily patrol bringing food and clothing to the homeless in the city's hardscrabble Praga district, said she has been unrelentingly busy since the cold snap started.
"New (fatal) cases are reported to us daily. Just today we got calls telling us about two new ones, one of someone who was living in a tent and another of someone in an abandoned train station," Golebiewska said. "I've got more and more people to feed, but just 40 portions of soup a day."
Overall, 107 people have died of hypothermia in Poland since winter hit in November. The current cold snap began at the end of January and across the continent, authorities have reported at least 360 weather-related deaths.
In neighbouring Lithuania, where the mercury has dipped to minus 31 Celsius (minus 24 Fahrenheit), the deaths of 12 more people over the weekend brought the cold snap's toll to 23.
