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. Debris flows may reach the valley bottom even if they are triggered high in the terrain. Some landslides are expected. A few large slides may occur. Exposed railways and roads may be closed.
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.
Warning level meaning Challenging situation which requires monitoring and may cause local damages. Yellow level is the lowest of our warning levels.
