Cyclone Herwart was a European windstorm that affected Southern Denmark, Germany, Poland, Austria, Hungary and the Czech Republic on 28–29 October 2017. Named by the Free University of Berlin Meteorology Department,[5] the storm was an extratropical cyclone formed as a secondary low to a more northerly centre of low pressure named Grischa coming southward from the Svalbard Islands region, the latter splitting in two low-pressure areas late on 28 October.[6] The center of Herwart started rotating counterclockwise around the main low pressure area, passing over Norway, Sweden, Latvia and then losing power while moving over western Russia.[7]
In Denmark, which was hit on 28 October, the storm was named Ingolf.[8] In Hungary, the storm was named Nárcisz (Narcissus), a Hungarian female name whose name day is on 29 October.[9]
