The matter in summary: Stormy weather is expected this weekend, especially in Northern Norway and Western Norway, with the risk of floods, avalanches and strong winds. In Western Norway, up to 90 millimeters of rain is expected in 12 hours on Saturday, and flood warnings have been issued for Saturday, Sunday and Monday. In northern Norway, significant amounts of rain and strong gusts of wind are expected, with up to a full storm on the coast on Sunday. In Eastern Norway it is calmer, but a danger warning has been issued for ice and difficult driving conditions due to the transition to mild weather. NVE warns that all the rainfall and mild weather can lead to heavy snowmelt and stormwater, which can lead to local floods, landslides and ice. There is a high risk of naturally triggered avalanches in both Vestland county and Nordland. The summary is made by an AI service from OpenAi. The content is quality assured by news’s journalists before publication. It will be smooth roads. Strong gusts of wind. High avalanche danger. Flood risk. And a lot of rain. In other words, the weekend can be weather-wise chaos. – It will be a weekend with a lot of weather, summarizes meteorologist on duty Rannveig Eikill. It is mainly Western Norway and Northern Norway that are the weather losers. In Western Norway, it is the rain that will play the main role. The meteorologists have sent out an orange danger warning on Saturday, and up to 90 millimeters is expected in 12 hours in central and inner parts of Vestland. In Rogaland, 60-80 millimeters of rain can be expected in 24 hours from Saturday afternoon. Locally, 100 millimeters may fall. A flood warning has also been issued on Saturday, Sunday and Monday. According to NVE, there will be an increased risk of avalanches, floods and landslides, mudslides and flash floods in large parts of Nordland and in Western Norway. Strong winds in the north In northern Norway, there will also be significant amounts of rain. But strong gusts of wind have also been reported here, particularly in Nordland. On Saturday, locally strong gusts of up to 34 meters per second are expected from the southeast and strong gales in several places. On Sunday, the wind will turn and then it will be even worse. Locally strong gusts of up to 37 meters per second are then expected from the west and up to a full storm on the coast. – There is a strong low pressure coming in and causing a lot of stormy weather in much of the country, says Eikill. She says that it is Nordland that will receive both the most precipitation and wind in the north. – But it is a bit uncertain which part of Nordland gets the strongest wind. The strong low pressures not only cause a lot of weather and wind on the mainland, they also cause high waves at sea. On Sunday, waves of up to 10 meters are expected on the outside of Lofoten and Vesterålen, reports the Meteorological Institute. There may be a risk of damage to infrastructure and buildings in the beach zone. On Saturday, locally strong gusts of up to 34 meters per second are expected from the south-east and strong gales in several places in Nordland.

Neither precipitation nor wind is expected. But due to the transition to mild weather, a danger warning for ice and difficult driving conditions has been issued. There is a risk of slippery roads in Southern Norway as well. Here, a south-westerly stiff gale is also expected on Saturday and Sunday. In Trøndelag, large amounts of precipitation are also expected, and there is also a high risk of avalanches on Saturday. There is a local danger of ice and difficult driving conditions due to the transition to mild weather. Night to Saturday there may also be rain that freezes on the ground from Oslo and northwards. Photo: Meteorological institute NVE warns According to NVE, all the precipitation and mild weather will lead to heavy snowmelt and stormwater, which can lead to local floods, landslides and ice. The high avalanche danger means that there is a high risk of naturally triggered avalanches in both Vestland county and Nordland. NVE writes that there is tele on the ground and ice in many places. It will prevent the rain from penetrating into the ground and can lead to local flooding. Mild temperatures and rain will lead to more water in rivers and lakes, which in turn will break up the ice and carry it down the waterway. – We recommend that municipalities, emergency responders and residents who live exposed to use the time before the rain comes to open up clogged gutters and manhole covers, says duty manager Anne Stavang. NVE asks municipalities, emergency responders and residents who live at risk to take preventive measures. In areas with a high risk of avalanches, it is important to stay away from avalanche terrain. Photo: NVE Great risk of avalanches In Western Norway, a lot of fresh snow in the mountains and rain in the lowlands could naturally trigger avalanches. In Nordland, large amounts of fresh snow on top of a weak snow cover can also lead to naturally triggered avalanches. Some of these can be large. – It is important to stay away from avalanche terrain, i.e. terrain that is steeper than 30 degrees and outlet areas where avalanches stop, says avalanche watch leader Markus Eckerstorfer. – If there is also a reported danger of slush avalanches, you must be aware that these can break loose in looser terrain and along streams, says Eckerstorfer, who also offers some good advice: – Roads can be closed and you should keep a good distance from steep terrain. Subscribe to danger alerts from Varsom and use the app to check avalanche terrain and areas that have been mapped for flood and avalanche danger. Improvement in sight Over the weekend there will be new low pressure. Also this time with wind and precipitation. But not as bad as last weekend. Over the course of the week, it currently looks calmer and colder. And maybe there will also be some snow on Christmas Eve.
