Danger levels
Orange - very heavy rainRead more about the severity levels at hjelp.yr.noRecommendations
- 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
- 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
- Debris flows may reach the valley bottom even if they are triggered high in the terrain
