The high pressure that has been over Scandinavia for the last few days will move south in the next few days. – Now this high pressure is being pushed south, and we are getting westerly weather over large parts of the country. Martin Granerød warns of a temperature change of up to 40 degrees in the south. Photo: Solveig Horvei / news Large parts of southern Norway will retain warm weather, but temperatures will gradually rise, says on-duty meteorologist Martin Granerød. For Eastern and Southern Norway, it will go from between 10 and 20 minus to between zero and five minus during the middle of the coming week, while Western Norway and Central Norway can already start to feel milder temperatures early in the week. – As early as tomorrow, it could be a plus degree or two in the outer regions of Western Norway. Freezing temperatures and snow chaos have characterized parts of southern Norway in recent days. It is still cold in the south.

But in just a few days the temperature rises by over 40 degrees, both in the south and in some places in Troms and Western Finnmark. On Thursday, the coldest temperature since 1999 was measured in Kautokeino. Then the measuring station showed -43.5 degrees. On Monday, temperatures of four degrees are reported in the same place, when the weather will be mild with rain from central Norway and northwards. Elise Gloppen Hunnes predicts a gloomy weather for Northern Norway.

The low pressure brings with it from the south which comes as rain. Fair weather is expected across the board, says Elise Gloppen Hunnes, meteorologist on duty at the weather forecast in Northern Norway. In the south, there will also be approximately equally strong temperature increases. In Dagali in Buskerud, 35.6 minus degrees were measured on Saturday, but eventually cold air masses from the east will be replaced by warmer air masses from the west. – In this area, the temperature will mostly approach zero degrees during the week. Maybe it will rise to a plus degree or two, so that there will be a temperature rise of close to 40 degrees, says on-duty meteorologist Martin Granerød. The large amounts of precipitation that have come in the form of snow will come this week in northern Norway in the form of mild weather and rain. In Nordland, a danger warning has been issued for up to 90 millimeters of rain in 24 hours from Monday morning Graphic: MET Great avalanche danger and slippery roads On Sunday, the weather change led to very slippery roads in Lofoten, Vesterålen and in the direction of Narvik. So far, there have been no traffic accidents on the roads, but some truck trains have had challenges. – Until it gets scattered, people have to adjust their speed according to the conditions, says traffic operator Arne Sætermo. From Sunday evening there is a local danger of ice in parts of Møre and Romsdal and Trøndelag. The Central Norway Traffic Center asks motorists to be extra attentive and to drive according to the conditions. Check the traffic reports here. Torghatten nord reports that the Levang-Nesna ferry connection has been canceled due to bad weather. From Sunday evening it will also be smooth in Trøndelag and Møre and Romsdal. Illustration: Meteorological Institute Temperature fluctuations in the north and heavy rainfall lead to an increased risk of avalanches. Over large parts of northern Norway, danger level four for avalanches is expected from Monday. This is the next highest degree of danger, and means that the danger is great. – We expect that there will be many naturally triggered avalanches, says Jostein Aasen, avalanche warning at NVE. This applies from North Troms and southwards to Svartisen south of Bodø with the exception of Lofoten and Vesterålen. In Vest-Finnmark, Lofoten and Helgeland, the danger level will be three. The Norwegian Water Resources and Energy Directorate does not recommend driving in landslide terrain, and landslides can hit landslide-prone roads and buildings. Hoping for rain On Sunday morning, a county road on Arnøya in Troms was closed due to an avalanche. Avalanche warning in NVE Jostein Aasen explains that a long cold period with little precipitation has led to the existing snow cover being unstable and not solid enough to receive the amounts of precipitation expected on Sunday and Monday. Avalanche warning in NVE, Jostein Aasen, says that there won’t be any nice hiking weather in the north for the next few days – and also dangerous in avalanche terrain. Photo: private – We will get 20-30 millimeters of rain on Sunday, then it will continue with up to 50 millimeters of rain on Monday. Part of the precipitation comes as rain, so we get both fresh snow and rain at an altitude of up to 800 metres. In addition, there will be stiff gales from the southwest, says Aasen. In other words, a recipe for an avalanche. On varsom.no there is a map showing terrain where snow can loosen and the discharge areas. Aasen encourages people to check the map before going on a trip. – But when you look at the weather forecast for Monday, I would have chosen another day to be outside, he says. At high altitudes, most of the snow will be packed, which can lead to naturally triggered avalanches. In the lowlands below 800 metres, it is currently uncertain. – If all that comes from precipitation on Monday is rain, then it doesn’t have to be so dangerous. But if you get fresh snow and then rain, then we have an unfavorable combination with lots of fresh snow that will lead to wet snow avalanches, says Aasen. While in the north this week there won’t be anything similar to hiking weather, here in the Sunnmør Alps, it will be both much safer and nicer hiking weather. Photo: Tore Ellingseter Danger level 2 in the south Over most of southern Norway, there will still be danger level 2 – moderate risk of landslides – into next week. – In southern Norway, it has been cold and stable weather for a long time: there is therefore a snow cover that has been around for a long time since the last time anything happened. There has been a build-up of edge cards, which are persistently weak layers in the snow cover. But there are only a few places where it is possible to trigger avalanches, says Aasen.
