In Fredrikstad, a change in weather led to treacherous conditions for pedestrians, resulting in dozens of falls due to supercooled rain creating extremely slippery surfaces. Hospitals have reported a surge in related injuries.

The last time the water levels were this high in some places was in the late 1990s or early 2000s. According to the Finnish Environment Institute (Syke), floodwaters will likely spill onto fields and roads in parts of southern and western Finland, but not into buildings.

Packed ice crystals have pushed up water levels on the Kokemäki River, soaking some buildings in Huittinen and Pori.

Mild, wet weather has raised water levels in rivers and lakes around the country.
