Water discharge is expected to increase because of rain and snowmelt. This may cause local inundation where river channels are filled with ice and because of frozen ground. It also may cause ice drift in streams, with subsequent local inundation.
Area
Applies to høyfjellet i Sør-Norge.
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.
Hydropower production will in some cases act as flood control, and therefore the issued warning will not necessarily apply to all regulated waterways.

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
Extensive flooding, erosion damage and flood damage in exposed places. May cause closed roads and bridges.
The three severity levels
Orange - considerable dangerRead more about the severity levels at hjelp.yr.no
Steep slopes, as well as streams and rivers with high discharge, are particularly exposed. Rain is expected, followed by heavy showers in some places. Relatively high temperatures and windy conditions causes significant snowmelting.
Area
Applies to deler av Møre og Romsdal, Vestland, Innlandet og Viken.
Instructions
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.
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.
