Consequence

Many landslide events, some with considerable consequences. Major events may reach settlements, roads and railways. 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. Slush slides: A flow of waterlogged snow. These landslides can start in relatively flat terrain and seek towards streams and steep slopes.

Advice

Stay updated on the latest weather developement and hydrological situation. Follow the weather forecast and radar at yr.no, and updates on varsom.no. Keep away from steep slopes, as well as streams and rivers with high discharge. Cleaning of drainage paths and culverts are recommended. Keep water paths and culverts free from snow, ice, sediments, waste, twigs and leaves. Municipalities, Counties and other emergency operators should continuously evaluate the need for preparedness and prevention measures.

Description

Risk of slush flows is especially high in areas with more than 30-50 cm snow. Slush flows are triggered even in gentle slopes, where water accumulates. Slush flows follow terrain depressions and may develop into debris flows.
