Southern Finland has also been in a deep freeze. The mercury plunged to below -30 degrees at the weekend, setting cold records for the South this winter.
In Lappeenranta’s Konnunsuo the temperature fell to -37 degrees, while Helsinki was chilled to -25 degrees, as measured in Kaisaniemi.
On Sunday, the cold has brought disruptions and delays to long-distance train-traffic, including the Allegro service between Helsinki and St. Petersburg. However, road traffic has been moving mostly as normal.
According to YLE meteorologists, severe cold weather is set to continue in most of the country. South of the line running between Helsinki and Vaasa the skies will get cloudier, with southerly winds picking up. These changes will bring up the mercury to temperatures of less than -10 degrees Celsius.
