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.
Municipalities, Counties and other emergency operators should continuously evaluate the need for preparedness and prevention measures. 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.
Severe situation that occurs rarely. Steep slopes, as well as streams and rivers with high water discharge are particularly exposed. Combination of high temperatures and windy conditions can cause snowmelting. The soil water content will increase due to snowmelt and rain. This will increase the danger of slushflows and landslides along rivers and streams, and in slopes where there is snowmelt. Risk of slushflows is especially high in areas with less than 1 meter deep snow. Slushflows are triggered even in relatively gentle slopes, where water accumulates. Slushflows follow terrain depressions and may develop into debris flows. Areas with new snow are particularly exposed. Heavy rain is expected up to 100 mm in Vestland and Møre og Romsdal and up to 40 in Trøndelag.
