The water discharge is expected to increase rapidly in small and medium sized rivers is expected. Local flooding and erosion damage. Large amounts of rain are expected in the warning area.
Area
Applies to Rogaland og Vestland.
Instructions
Stay informed on the situation. Secure and/or move assets away from vulnerable areas (car, caravan along rivers/streams, basements). Cleaning of drainage paths and culverts is recommended. Keep away from rivers and streams with high flow.
Consequences
Local flooding and/or erosional damage in streams and small rivers. Stormwater in urban areas.
From Friday afternoon to Sunday afternoon blowing snow is expected due to snow and strong westerly winds.
Area
Applies to Fjellet i Soer-Norge.
Instructions
Allow extra time for transportation and driving. Follow advice and check status from transport operators. Check road reports (175.no). Use tires fit for winter conditions and use caution while driving. Avoid unnecessary journeys to exposed places.
Consequences
Reduced visibility. Local driving conditions may become difficult due to snow accumulating on the road. Expect convoys and/or closed roads on short notice.
Timeline
- Friday, 28 January 15:00 - ongoing danger
- Sunday, 30 January 15:00 - danger is over
Rain is expected up to 1000 meters above sea level. Landslides may be expected. Exposed railways and roads may be closed. Slushflows are triggered even in relatively gentle slopes, where water accumulates. Slushflows follow terrain depressions and may develop into debris flows. Steep slopes, as well as streams and rivers with high discharge, are particularly exposed. Relatively high temperatures and windy conditions causes significant snowmelting. Groundwater and soil moisture are high.
Area
Applies to Vestlandet.
Instructions
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.
Consequences
Landslides may be expected. Exposed railways and roads may be closed. Debris flows may reach the valley bottom even if they are triggered high in the terrain.
