Consequence Some landslides are expected. A few large slides may occur. Exposed railways and roads may be closed. Debris avalanches/shallow slides are soil slides and rapid movement of saturated soil in steep terrain. 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 water paths and culverts free of snow, ice, gravel, waste, twigs and leaves. Clogged waterways with dammed water may cause landslides. 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.
Warning level meaning Challenging situation which requires monitoring and may cause local damages. Yellow level is the lowest of our warning levels.
