Storm Ciarán, known in Germany as Storm Emir[7] was a European windstorm that severely affected parts of Europe from late October to early November 2023. Part of the 2023–24 European windstorm season, Ciarán impacted northwestern Europe and killed 21 people, eleven of whom were in Italy and four in France. It also caused mass disruption to transport. Widespread damage from 100 miles per hour (160 km/h) winds were reported in the Channel Islands, while 1.2 million French households were left without electricity.[8][9]
Prelude
Storm Ciarán was named by the United Kingdom's Met Office on 29 October, while the Free University of Berlin in Germany named the system Emir on 30 October.[7] It was expected to bring winds of 90 to 120 km/h (60 to 70 mph) widely with >130 km/h (>80 mph) on some coasts. More heavy rainfall was expected to fall which would exacerbate the flooding from Storm Babet a week prior.
The Met Office's long-range forecast stated that Storm Ciarán would move away on 3 November, with many places still with blistering winds and rain spells.[10] The Channel Islands were due to be hit with gusts around 95 mph (153 km/h) with schools closed and a red weather warning in place. On 1 November, this was updated to a Force 11 violent storm, with the Met Office stating that Storm Ciarán was undergoing explosive cyclogenesis.[11]
The storm would impact the Netherlands on 2 November.[12] The storm especially affected the Isle of Jersey, where a strong thunderstorm formed a tornado alongside the golf ball sized hail with windspeeds of the storm reaching over 100 mph (160 km/h).[13][14]
