On Friday, the Danish Meteorological Institute (DMI) had forecasted up to 80 millimeters of rain on Saturday, but the actual precipitation turned out to be far less. On Saturday evening, the DMI revoked their warning of heavy rain and cloudbursts. This was announced in a post on the social media platform X shortly before 8 p.m.
Initially, large amounts of rain were forecasted in three municipalities in northern Jutland as well as on Læsø, which is one of the last places on the Danish map. This risk alert was lifted around 8 p.m. after the forecasts had changed. On Friday, the DMI had warned that between 50 and 80 millimeters of rain could fall in a day on Saturday, with the possibility of a 100-year event in several places. A 100-year event is a statistical term for an amount of precipitation that is only expected to occur once every 100 years.
However, these concerns did not materialize. Already around noon on Saturday, the DMI revised their forecasts and announced that there would be less rain than originally anticipated. Meteorologist Jens Lindskjold from the DMI stated: “We are so far away from a 100-year event that we can confidently say: It simply doesn’t happen.”
While a 100-year event was avoided, according to the DMI’s update on X on Saturday evening, they came close to a 10-year event. The Institute’s latest measurements showed that 55.6 millimeters of rain fell between Randers and Hobro in East Jutland. According to the climate atlas, a 10-year event in Denmark usually means 56.2 millimeters of rain in 24 hours.
Other areas in East Jutland also experienced significant amounts of precipitation. In Grenaa, nearly 50 millimeters of rain were recorded, while areas just north of Aarhus saw up to 50.4 millimeters. On Saturday afternoon, the DMI adjusted their expectations for the total amount of precipitation for the day to between 25 and 35 millimeters, significantly less than the earlier forecasts.
According to the Danish Preparedness (Danske Beredskaber), Saturday passed without the need for special interventions, and Banedanmark reported that the weather did not pose challenges for public transportation.
