Storm Poly

Storm Poly, also known as Cyclone Poly, was a powerful European windstorm and a rare summertime cyclone. The storm affected the Benelux, Germany, and the United Kingdom during July 2023. The thirty-seventh windstorm of the 2022–23 European windstorm season, Poly was named by the Free University of Berlin on 4 July. It later became the most intense summer storm to impact the Netherlands since the start of the measurements, peaking at 148 km/h (92 mph) in IJmuiden. In Germany, lesser winds of 80–97 kilometres per hour (50–60 mph) were recorded. In total, two fatalities occurred: one in the Netherlands, and another in Germany. Poly caused at least €50,000,000 (2023) in damages. According to a research conducted by the Utrecht University and the Royal Dutch Meteorological Institute, Poly could be classified as a hybrid cyclone.
