High temperatures and strong snowmelt are currently prevailing throughout Norway. Rain is also expected on Monday and Tuesday. Therefore, both a flood warning and a threat related to soil, slush and landslides are in effect for the next few days.
A yellow warning has been issued for Monday and Tuesday for Trysilelva and Glomma north of Årnes.
– Scattered showers are expected on Monday and Tuesday, which, along with a lot of melting snow, creates a risk of flooding, says Erik Holmquist, an observer at NVE. we also have flood warning for areas coastal between Vesterålen and Tana.

Cooler weather is expected on Wednesday and Thursday, which will result in less snow melt. Water flow is expected to drop slightly again from Wednesday before temperatures and water flow are expected to pick up again later in the week. The situation is very sensitive to temperature and precipitation.
A yellow warning for landslides, mudslides and flooding is still in effect for large parts of eastern Norway and Trøndelag until Tuesday morning.
"In recent days, large parts of southern and eastern Norway have melted as much snow as if 20-30 mm of rain fell every day," says Ivar Berthling, an observer at NVE.
There is already a high water content in the soil
“This leads to an increased risk of landslides, mudslides and landslides because there is already a high water content in the ground. Valley areas where there is still a lot of snow in the mountains are most at risk. The risk of avalanches appears to have decreased as early as Tuesday as the weather cooled down and snowmelt slowed, Bertling added.
A warning was also issued today about the increasing risk of landslides, mudslides and flash floods for Troms and Finnmark. There, snow has been melting continuously for several days and, combined with rain, gives a high water content in the soil. Snow melt is expected to remain high on Tuesday as well.
– Stay away from steep slopes, especially streams and rivers with high water flow. Flood and mudslides can come very quickly and unexpectedly, says Ivar Berthling, landslide warden at NVE.
