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.


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.


The amount of water in the soil is significant. Steep slopes, as well as streams and river with high discharge are particularly exposed.
