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 in the Drammen river basin is at yellow level many places Wednesday morning. Consider also the orange flood warnings for lakes Krøderen and Sperillen.
