Type

Landslide

Heavy rain is expected. Relatively high temperatures and windy conditions, causes significant snowmelting. Snowmelting will occur even in the high mountains Significant snowmelting will occur in the valleys.

The amount of water in the soil is significant. 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. Debris flows may reach the valley bottom even if they are triggered high in the terrain.
Danger increase Monday morning
Danger decrease Tuesday evening
Consequence Some landslides are expected. A few large events may occur. Exposed railways and roads may be closed. 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. Slush slides: A flow of waterlogged snow. These landslides can start in relatively flat terrain and seek towards streams and steep slopes. Along the watercourses in the flood areas: High discharge can lead to excavation of masses at the foot of slopes. Rapid lowering of water levels after flood can also cause local landslides.
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.
Warning level meaning Challenging situation which requires monitoring and may cause local damages. Yellow level is the lowest of our warning levels.
