Thousands of households across northern Sweden and southern Finland were without power Wednesday after a heavy snowfall, and forecasters warned that particularly icy temperatures lay ahead for the Baltic Sea region. In southwestern Finland, some 4,000 households were without power, according to Finnish broadcaster YLE, with authorities saying that number could rise. In Sweden, electricity provider Eon said some 3,000 homes were affected and added that power outages may go on longer than usual because it may be too risky to send out maintenance workers. The Swedish weather service said the snowfall, which had affected the northern part of Sweden over the past 24 hours, was still taking place but was slowing down. The Swedish Meteorological and Hydrological Institute reported snow depths of up to 60 centimeters (24 inches) in northern Sweden.
