Most of Finland on Monday was experiencing a return of wintry weather with high winds, rain, sleet and snow.
Southern areas, where temperatures continue to be well above freezing, will get off easier. Daytime rain and sleet in the south are, however, expected to turn to light snow overnight.
In central regions, snow accumulation could reach as much as 10cm by Tuesday morning, according to Yle Meteorologist Anniina Valtonen.
Tuesday night may well bring a further 5cm of snow to central Finland. At the same time, storms are in the forecast over western sea areas.
Power companies have made preparations to deal with heavy snowfall, though it is unlikely that this week's weather will lead to major outages.
This past weekend, daytime temperatures were over 10C in large parts of the country, but have now dropped to just a few degrees above freezing in most areas.
Even though there have been major temperature variations seen, this is not unusual for the time of year, according to Valtonen.
"This is normally a part of the arrival of spring," she says.
Meanwhile the Finnish Meteorological Institute advises motorists not to switch to summer tyres just yet.
