Storm Aurore was a notably early extratropical cyclone in late October 2021 that impacted several areas of Europe, causing substantial damages. The third named storm of the 2021–22 European windstorm season, Aurore was first noted on 20 October by Meteo France over the Atlantic Ocean, south of Ireland. As the system moved over central Europe on the next day, it subsequently merged with another extratropical cyclone named Hendrik before moving across central Europe, in which it brought several destruction across the region. It then was last noted on 23 October.

Gusts of 175 km/h (109 mph) were recorded in an area in Normandy, the highest in association with the storm. Many trees across the affected areas felled, while over half a million people lost electricity. Public establishments were also closed as a precaution to winds and flooding. Flash floods also affected the U.K. and a total of six deaths were confirmed from the system: Four in Poland, one in the United Kingdom and another in Germany. Damages were estimated by the Aon Benfield at greater than or equal to $100 million.^[2]
