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.


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.


Steep slopes, as well as streams and rivers with high discharge, are particularly exposed. Heavy rain is expected. Rain is expected, followed by heavy showers in some places. The amount of precipitation, or its location, is somewhat uncertain. Follow the weather radar. Local heavy rain showers can intensify landslide hazards where heavy rains hit. See warning for heavy rainshowers.
