Rain followed in some places by heavy showers is expected. Relatively high temperatures and windy conditions, causes significant snowmelting.

Steep slopes, as well as streams and river with high discharge are particularly exposed. Risk of slush flows is especially high in areas with more than 40 cm snow. The snow may in some places be fully water-saturated. Slush flows are triggered even in relatively gentle slopes, where water accumulates. Slush flows follow terrain depressions and may develop into debris flows.
Danger increase Friday evening
Danger decrease Monday early morning
Altitude 0 - 1000 masl
Consequence Some landslides are expected. A few large events may occur. Exposed railways and roads may be closed. Slush slides: A flow of waterlogged snow. These landslides can start in relatively flat terrain and seek towards streams and steep slopes. Debris avalanches/shallow slides: Soil slides and rapid movement of saturated soil in steep terrain. Debris floods: A "flood" of water, soil and rocks in steep creeks. Surface runoff in steep terrain can cause streams to change regular flow patterns.
Advice 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.
