The police department of Southwestern Finland warns people driving in the region of wandering elk that may cross roads unexpectedly in search of fresh drinking water.
The ongoing heatwave is drying up the drinking holes and ponds that elks use to stay hydrated, forcing the animals to seek larger bodies of water outside of their natural habitats.
A total of 140 crashes and other accidents involving elk have been reported in the last week alone, police said, especially in the area around Pyhäjärvi lake near the town of Säkylä in the southwest of Finland.
The number of accidents is exceptionally high, according to inspector Marko Luotonen of the Southwestern Finland police department.
"I don't recall there ever being this many collisions in July," he said.
Police urge drivers to stay especially alert and to drive slower on roads that pass near bodies of water.
Do not disturb swimming animals
The elk (Alces alces) is Finland's largest animal, and the species is known to jump into lakes for a swim in order to cool off on hot days.
Police issued a reminder that animals such as elk seen swimming in a body of water should be left alone and not approached.
"All wild animals must be allowed to swim in peace and move on to their natural routes," Luotonen said. "If a swimming animal is disturbed it may become distressed and even drown."
