Finland saw a sharp turn to winter with temperatures down to –20°C in Lapland and widespread snowfall, prompting traffic weather warnings in eastern and northern regions.

Heavy snowfall caused widespread power outages in Salla and eastern Lapland, leaving some customers without electricity for over 16 hours as repair crews worked into the evening. Thousands lost power at the peak; even a mobile phone base station went down.

January in Finland showcased extreme contrasts with Lapland recording frigid temperatures, including a low of -38.9°C, while southern regions experienced unseasonably mild conditions with a peak of 9.5°C driven by föhn winds.

A cold wave from Siberia and Finland is bringing frigid temperatures to Norway, with conditions falling to minus 25 degrees Celsius in some parts.
