The heaviest snowfall was early Monday evening, over 4mm of precipitation an hour. A general meteorology rule of thumb is that one millimetre of measured precipitation equals one centimetre of snow.
Road conditions in the region are expected to remain hazardous until at least early evening on Tuesday. One person died Tuesday morning in a collision between a car and a delivery lorry in Jyväskylä.
An air dome at Jyväskylä's Vehkalampi sports venue was taken down when the weight of snow began to raise safety concerns.
"This is the first time we've had to do this. These conditions are impossible. Of course we're not open," commented Jarmo Korhonen who supervises the facility for the city of Jyväskylä.
