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.
Construction work in areas with clay is not recommended. Keep away from steep slopes.
The soil is water-saturated. Steep slopes, as well as streams and river with high discharge, are particularly exposed.
