Consequence Some landslides are expected. A few large events may occur. Exposed railways and roads may be closed. Debris avalanches/shallow slides: Soil slides and rapid movement of saturated soil in steep terrain. Debris flows: A "flood" of water, soil and rocks in steep creeks. Surface runoff in steep terrain can cause streams to change regular flow patterns. Many landslide events are expected, some with considerable consequences. Major events may reach settlements, roads and railways. Along the watercourses in the flood areas: High discharge can lead to excavation of masses at the foot of slopes. Rapid lowering 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 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.
Warning level meaning Severe situation that occurs rarely, requires contingency preparedness and may cause severe damages within some extent of the warning area. Orange level is the second highest of our alert levels.
