Consequence

Landslides may be expected. Exposed railways and roads may be closed. Along the watercourses in the flood areas high discharge can lead to erosion of masses at the foot of slopes. Rapid decline of water levels after flood can also cause local landslides.

Advice

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.

Description

Steep slopes, as well as streams and rivers with high discharge, are particularly exposed. Rain is expected, followed by heavy showers in some places. Groundwater and soil moisture are high. The expected rain will increase the danger of landslides. Rain is expected, followed by heavy showers in some places. Groundwater and soil moisture are high.
