Type

Landslide

Heavy rain is expected, as rain up to 800-1000 meters above sea level. Heavy rain is expected.

The soil is water-saturated. 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 Friday morning 21. Feb. 2020
Danger decrease Sunday morning 23. Feb. 2020
Altitude 0 - 1000 masl
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 flows: 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.
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.
