Consequence

Some landslides are expected. A few large slides may occur. Exposed railways and roads may be closed. Debris avalanches/shallow slides are soil slides and rapid movement of saturated soil in steep terrain. Debris flows are a "flood" of water, soil and rocks in steep creeks. Surface runoff in steep terrain can cause streams to change regular flow patterns. Slushflows are flows of watersaturated snow. These slides 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.

Description

Some landslides are expected. A few large slides may occur. Exposed railways and roads may be closed. Risk of slushflows is especially high in areas with more than 50 cm snow. The snow may in some places be fully water-saturated. Slushflows are triggered even in relatively gentle slopes, where water accumulates. Slushflows follow terrain depressions and may develop into debris flows. Relatively high temperatures and windy conditions causes significant snowmelting.
