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.
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.
From early Saturday morning to Saturday afternoon 50-70 mm of precipitation is expected in 12 hours. The precipitation is expected as snow above approximated 1000-1200 m. Largest accumulations are expected in middle regions.

Loose items may be taken by the wind. Possibly cancelled departures for ferry, plane, or other transport. Bridges may be closed. Some journeys may have longer travel times. The power supply may be impacted, due to tree(s) falling over. Some roads may be closed due to trees or other objects in the road. Blowing snow causes reduced visibility and possibly convoys and/or closed roads. High waves may cause damage to infrastructure and buildings in the coastal zone. The strong wind may cause locally high waves in fjords and lakes.
