Local flooding and/or erosional damage along the rivers.
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.
The water discharge is increasing in the Drammen river basin, and at yellow level many places Tuesday morning. Consider also the orange flood warnings for lake Krøderen and lake Sperillen.
