The Emergency Response Centre Agency took to Twitter on Monday to warn people about weakening ice on lakes and waterways across Finland.
In recent days, the emergency services have received several reports of people stranded in water due to weakened ice.
The emergency response service noted that the recent sunny days have made the ice cover brittle and the thickness of the ice does not necessarily indicate how strong it is.
"In many places, the ice is no longer accessible," the tweet said.
Deceptive snow cover
Snow cover can also make it difficult to assess the strength of the ice.
According to Yle forecasts, southern Finland is expected to receive up to 15 centimetres of snowfall between Monday and Tuesday, making the strength of the ice on lakes more difficult to assess.
