The extreme weather Hans is bringing an extremely large amount of rain over Southern Norway.
A red danger warning for extremely heavy rainfall has been issued for parts of Southern Norway. In many places, the event will be among the strongest in the last 25 years. The red level signifies the highest level of risk for rain.
On the East Coast, north of Oslo, as well as the eastern parts of the former counties of Sogn og Fjordane, Møre og Romsdal, and the southern part of Trøndelag, extreme amounts of rain are expected, 80-100 mm within 24 hours.
The danger warning is in effect from Monday morning until Tuesday evening.
The precipitation approaches from Sweden on Sunday evening and increases in intensity on Monday morning. The heaviest rainfall is expected from Monday afternoon to Tuesday afternoon. There is also a risk of heavy rainfall during the warning period, 20-35 mm per hour. Due to the uncertainty regarding heavy rainfall, it is also uncertain where exactly the highest daily values will occur.
In addition, an orange-level warning for rain is in effect, indicating 60-80 mm within 24 hours, as well as a yellow-level warning, indicating 40-60 mm within 24 hours, in the areas surrounding the red danger warning. Most counties in Southern Norway will be affected to a greater or lesser extent.
