The Norwegian Meteorological Institute has issued a yellow warning for rain for large parts of Eastern Norway from Monday afternoon. They write on X that locally very heavy rain showers are expected. A warning has also been issued about the risk of flooding in the north of the interior. In addition, a warning has been sent out about the risk of landslides and floods. The danger alerts are at the yellow level, which means moderate danger. – In parts of the warning area, there may be 40-50 mm of rain during the afternoon, says meteorologist on duty at the Meteorological Institute, Per Egil Haga. The weather can have consequences for traffic, such as stormwater and closed roads, according to yr.no. Yr recommends motorists to drive according to the conditions and check road announcements on 175.no. The meteorologists write that the water flow will increase rapidly in streams and smaller rivers.

Therefore, people should stay away from rivers and streams with a large flow of water. – There will probably not be flooding in the large rivers, but we can expect a fairly rapid increase in the flow of water in smaller rivers and streams, says NVE watchman Kristian Nordtun. NVE sees reason to give notice, partly because of the large amount of tourist traffic in the mountain areas. Streams that had little water at the weekend can now be very large. – What you crossed yesterday may not be possible to cross today and tomorrow, says Nordtun. Typical problems can be clogged pipes and culverts under roads. It is raining heavily over Eastern Norway today, and several product warnings have been sent out.

The magazines in the Mesnavassdraget are full. By draining the dam, they can release the water in a controlled manner into the river if there is a need for it. Lillehammer municipality writes this on its website. As a result, there will be a lot of water in the Mesnaelva, and the municipality asks people to keep a safe distance. Large local variations Both NVE and the Norwegian Meteorological Institute stress that there will be large local variations in rainfall intensity. And the weather can change quickly. Meteorologist on duty, Per Egil Haga, says they expect the most intense rain later in the afternoon today. Tonight, the rain will move a little eastwards. – The weather will then be lighter in Valdres and parts of Gudbrandsdalen, while there will still be some precipitation in the eastern part of old Hedmark throughout the day, says Per Egil Haga.

Lightning and more torrential rain tomorrow On Tuesday, even more pronounced torrential rain showers are expected, especially in the afternoon and evening. – They will be a little more local, but then there may be a lot of rainfall, over 20, maybe 25 mm of rainfall within an hour in a small area. And there could be a lot of lightning and thunder, says the meteorologist on duty. This weather can be just as big a challenge as today’s rainy weather. But the rain showers on Tuesday are expected to hit even more locally than today. Published 22.07.2024, at 10.22 Updated 22.07.2024, at 14.22
