Noen kommuner i Møre og Romsdal er lagt til varslet. Varslet er også forlenget til å gjelde for tirsdag 26.mai.



Snowmelt will occur even in the high mountains. Groundwater and soil moisture are high. It is forecast rain that will increase the danger for landslides.

The soil is water-saturated. Steep slopes, as well as streams and river with high discharge, are particularly exposed. Risk of slush flows is especially high in areas with more than 40 cm snow. The snow may in some places be fully water-saturated. Slush flows are triggered even in relatively gentle slopes, where water accumulates. Slush flows follow terrain depressions and may develop into debris flows.
Danger increase Friday morning 22. May. 2020
Danger decrease Wednesday morning 27. May. 2020
Altitude 0 - 1200 masl
Consequence 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 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.
Warning level meaning Challenging situation which requires monitoring and may cause local damages. Yellow level is the lowest of our warning levels.

The warnings are valid from 07.00  - 07.00.
