This comes after unprecedented warm weather across Europe thawed the snow on ski slopes and forced ski resorts to close this winter. French resorts near Mont-Blanc had to cancel the World Cup telemark ski race. Some ski destination had to resort to artificial snow. Since the majority of the snow had melted from the slopes, many ski resorts in France and Switzerland announced that they would be closed. Among the countries affected by the winter heatwave were Denmark, France, Germany, Poland, Spain, and Switzerland which had their warmest January days on record, with temperatures climbing to 21 degrees Celsius.
