Applies to Vestlandet, Trøndelag og deler av Nordland
Heavy rain is expected, up to 100 mm/day. Relatively high temperatures and windy conditions, causes significant snowmelting. Snowmelt will occur even in the high mountains. 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. Slush flows are triggered even in relatively gentle slopes, where water accumulates. Slush flows follow terrain depressions and may develop into debris flows. Debris flows may reach the valley bottom even if they are triggered high in the terrain.

InstructionsKeep 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 Central 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.
