A weather system bringing cooler temperatures and rain reached some western areas of Finland by Monday afternoon and heavy downpours are expected in many areas of the country as the week progresses, according to Yle meteorologist Anniina Valtonen.
Valtonen said the rain would be moderate to begin with, but will be extremely heavy in some areas on Tuesday. Particularly eastern areas - as well as northern Lapland - could get more rain than normally falls during the entire month of June, she explained.
Very heavy rainfall is particularly expected in an area stretching from Loviisa on the south coast 500km northwards to Kajaani on Tuesday, bringing as much as 50-70mm of rain. On Wednesday, the area is expected to get an additional 20-50mm more rain. The city of Kuopio, which is roughly in the middle of that area, got an average of 66mm of rain during the years 1981-2010, according to the Finnish Meteorological Institute (FMI).

Meanwhile, further up north, Lapland is set to get about 50mm of rain on Tuesday, 30mm on Wednesday and 5-10mm on Thursday.
There might even be some snow in store this week in the fells of northern Finnish Lapland, according to Valtonen.
FMI has issued warnings for heavy rain and thunderstorms across many areas of the country over the next few days.
