Consequence

Slushflows are expected, some with considerable consequences. Large slides may reach settlements, roads and railways. Slushflows may reach the valley bottom even if they are triggered high in the terrain.

Advice

Keep yourself updated about the development of the weather, the landslide and flood situation, and follow the weather radar. Keep away from steep slopes, as well as streams and rivers with high discharge. Keep water paths and culverts free of snow, ice, gravel, waste, twigs and leaves. Clogged waterways with dammed water may cause landslides. Municipalities, Counties and other emergency operators should continuously evaluate the need for preparedness and prevention measures.

Description

Risk of slushflows is especially high in areas with less than 1 meter deep snow. The snow is in some places fully water-saturated. Slushflows are triggered even in relatively gentle slopes, where water accumulates. Slushflows follow terrain depressions and may develop into debris flows. Rain and snowmelt will increase the risk of slushflows.
