We got a snowstorm today, wind speeds up to 30 m/s at sea, wave heights of 10 m, and 30-40 cm of snow on the ground. Traffic didn't get totally jammed, but didn't go all that fine either. In Helsinki I saw maybe six number 4 tram cars one after another when the first one had got stuck.
I didn't commute by bicycle or by car, using bus instead. Even though bus traffic was slow, at least it got you where you were supposed to go.
