Local flooding and/or erosional damage in streams and rivers. Stormwater in urban areas. Rapid increase of discharge in streams and rivers. May cause closed roads and bridges.
Stay informed on the development of the weather and the hydrological situation by following the weather forecast and weather radar, as well as updates on varsom.no. 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/streams with high flow.
Heavy rain will increase water discharge in rivers. Hydropower production will in some cases act as flood control, and therefore the issued warning will not necessarily apply to all regulated waterways.
