Radar image forStadlandet observation site, Selje (Sogn og Fjordane)
Ongoing: Flood risk. Caution level: orange (Hordaland og Sogn og Fjordane og Ottavassdraget i Oppland)
Precipitation and snowmelt due to high temperatures has resulted in high discharge in the rivers. The discharge will remain high monday. The combination of rain and continuous snow melting has increased water discharge. Water discharge is expected to sink as the temperature decreases and rain stops. Hydropower production will in some cases act as flood control, and therefore the issued warning will not necessarily apply to all regulated waterways. Read the full forecast on Varsom.no.

InstructionsStay 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. Keep waterways clear of snow and ice, sediments, garbage, twigs and leaves. Keep away from rivers/streams with high flow. 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 waterways clear of snow and ice, sediments, garbage, twigs and leaves. Keep away from rivers/streams with high flow. Read more at NVEFarenivå Orange
Weather radar for Western Norway
The map shows where precipitation (rain, sleet, snow etc) falls, the colour giving an indication of the amount.
By emitting radar waves the radar registers how precipitation moves . It will then receive echoes if the waves hit precipitation particles. The animation shows precipitation during the last hours, the last picture in the sequence being the most recent. The time at which it was taken is given (in local time) in the upper right corner.
Under certain conditions the radar waves are deflected and hit the ground instead, giving false echoes. False echoes can be recognised by being fairly motionless.
