Consequence

Some landslides are expected. 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. Slushflows: A flow of waterlogged snow. These landslides can start in relatively flat terrain and seek towards streams and steep slopes. Increasing water flow in streams may cause local flooding and ice jam flooding.

Advice

River erosion may trigger minor soil slips, which again may reduce the soil stability along the river. Be aware of such soil slips in areas with marine deposits. If such observations are made, do not hesitate to alert responsible municipal emergency staff at the local kommune. Keep away from steep slopes, as well as streams and rivers with high discharge.

Description

Steep slopes, as well as streams and rivers with high discharge are particularly exposed.
