Heavy snowfall brought both chaos and joy across Europe Monday, with some 15,000 people stranded overnight in the French Alps while skiers reveled in the fresh powder blanketing slopes. A winter storm left thousands of Britons without power, sent trucks sliding across icy highways in Germany and caused airport delays and traffic disruptions across the region. A Swiss national died and 30 people were injured, two of them seriously, in a highway pile-up some 40 kilometres (24 miles) from the Slovenian capital after heavy snow across the centre of the country, police said. The abundant powder created idyllic conditions for skiers in France and Germany, who have anxiously been watching bare slopes as temperatures remained unseasonably warm in recent weeks.
