Snow is blanketing southern areas on Saturday, reports the Finnish Meteorological Institute (FMI).
Snowfall is expected to strengthen throughout Saturday, the FMI said on Twitter.
An area stretching from Hanko to Porvoo will see the most white stuff—approximately five centimetres—according to the institute's forecasters.
Snowfall is contributing to slippery roads. The FMI has issued a traffic weather warning for Uusimaa through Sunday morning.
The current weather front could bring wintry landscapes as far north as Tampere.
Daytime highs on Saturday and Sunday will be a few degrees below zero, with the exception of the far north, where the mercury may plummet to -25 degrees Celsius on Sunday.
