The approaching snowstorm is going to bring up to 20 centimeters of snow to southern Finland. The driving weather is going to be bad over the weekend.

Today’s rain-in-your-face weather in Helsinki is going to turn into flurries and a snowstorm on Friday night.
“Most of the snow will fall in the southern parts of Finland and some of it will land in the western parts, too,” weather service Foreca noted on their website.
Meteorologist Joanna Rinne from Foreca said that as much as 10–20 centimeters of snow may fall in southern Finland over the weekend. The driving weather is going to be bad at least for the next two days.
The storm has been christened “Otto.” At this writing, it was unclear where the name derives from, but many hurricanes and cyclones have been called “Otto” in the past. What we do know, however, is that the storm created problems in Great Britain, then canceled ferries in Denmark and has blown up to 30 meters per second in Sweden.
In Finland, the gusts of wind may reach 20 meters per second in the coastal areas but likely not in inland areas.
The temperatures are going to be around minus 0 and 5 degrees Celsius in most parts of the country. On Sunday, the mercury is likely to drop to minus 7 degrees in southern Finland.
Next week is, according to Foreca, likely to be sunny and cold.
