  4. Applies to Nordland og Troms

    Rain followed in some places by heavy showers is expected. Relatively high temperatures and windy conditions, causes significant snowmelting. Steep slopes, as well as streams and river with high discharge are particularly exposed. Risk of slush flows is especially high in areas with more than 40 cm snow. The snow may in some places be fully water-saturated. Slush flows are triggered even in relatively gentle slopes, where water accumulates. Slush flows follow terrain depressions and may develop into debris flows.

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.
