Oppdatert informasjon -
Nordlige del av Nordland og sørlige del av Troms: varselet er nedgradert fra oransje til gult nivå. Med de gjeldende nedbør- og temperaturprognosene og en varighet på hendelsen som begrenser seg til lørdagsdøgnet, ventes ikke vannføringen å overstige oransje nivå i berørte elver og bekker.
Consequence
Extensive flooding, erosion damage and flood damage in exposed places. May cause closed roads and bridges. Local flooding and/or erosional damage in streams and small rivers. Stormwater in urban areas.
Advice
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. Emergency authorities must be prepared for the fact that building and infrastructure in general may be subject to serious incidents.
Description
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. Extensive flooding, erosion damage and flood damage in exposed places. Large amounts of precipitation are expected in the warning area. Hydropower reservoirs will in some cases act as flood control, and therefore the issued warning will not necessarily apply to all regulated waterways.
