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.

InstructionsKeep 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.
ConsequencesSituation that requires vigilance and may cause local damages
Weather radar for Western Norway
The map shows where precipitation (rain, sleet, snow etc) falls, the colour giving an indication of the amount.
By emitting radar waves the radar registers how precipitation moves . It will then receive echoes if the waves hit precipitation particles. The animation shows precipitation during the last hours, the last picture in the sequence being the most recent. The time at which it was taken is given (in local time) in the upper right corner.
Under certain conditions the radar waves are deflected and hit the ground instead, giving false echoes. False echoes can be recognised by being fairly motionless.
