  1. Warning sign

    Ongoing: Flood risk. Caution level: yellow (Deler av Østlandet og Telemark.)

    Large snow melting due to high temperatures is expected. Continuous snow melting will increase water discharge in small and medium sized rivers. 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.

Graph explanation. Hide explanation

The black line shows mean value (both precipitation and temperature). Some stations does not have mean values, and hence no black line.

The red/blue line shows average temperature during the day (24h) (equalized for 30 days). The line is red by pluss degrees, and blue by minus degrees.

The red/blue areas shows the temperature variations throughout the day (24h) with max- and min. temperature as endpoints. The area is red by pluss degrees, and blue by minus degrees.

The lightblue bars shows total precipitation this month. The black lines crossing is the normal (mean) value for precipitation.

The dark grey bars behind the precipitation bars shows snowdepth measured day by day.

Some stations only measures precipitation, while others only measures temperature. If an area or bar is missing the station does not measure this data.

NB! Precipitation is measured at 07 hours Norwegian time. The value (in mm) shows last 24 hours until 07 hours (08 hours summertime). Download other weather statistics from eklima.met.no.
