The Danish Meteorological Institute (Danmarks Meteorologiske Institut in Danish) has issued a warning for heavy rain and cloudbursts on Saturday evening, which now only applies to certain areas in Northern Jutland. According to the DMI’s website, the municipalities of Hjørring, Brønderslev, and Frederikshavn in Northern Jutland are affected by the warning. Previously, the DMI had issued a warning for heavy rain and cloudbursts for almost the entire country. On Friday, it was announced that between 50 and 80 millimeters of rain could fall during Saturday, which would be considered a so-called 100-year event. A 100-year event refers to a particular amount of precipitation that statistically only occurs once every 100 years within a day.
However, around noon on Saturday, this warning was adjusted. Meteorologist Jens Lindskjold from the DMI explained that the amount of precipitation would not reach the level of a 100-year event. He elaborated that there was a significant difference to this amount, and therefore it would not happen. Jens Lindskjold also highlighted that predicting rainfall and extreme weather is difficult. “Precipitation is our Achilles’ heel when it comes to predicting the weather most accurately. We have to rely on some models that have a certain degree of uncertainty. We try to communicate this uncertainty,” he said.
By Saturday afternoon, between 25 and 35 millimeters of rain had been recorded in East Jutland, northern parts of Zealand, and over the Limfjord. Locally, up to 50 millimeters could have fallen, according to the DMI.
