- 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
- Municipalities, Counties and other emergency operators should continuously evaluate the need for preparedness and prevention measures
- 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 mapped with quick clay, and areas with marine deposits
- If such observations are made, do not hesitate to alert responsible municipal emergency staff at the local kommune
Consequences
- Landslides are expected, some with considerable consequences
- Large slides may reach settlements, roads and railways
