Storm Aurore was an notable 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 Russia before dissipating on October 23.

In France, storm warnings were put in place by the Météo-France for Aurore, with an orange wind warning being issued on October 21. The cyclone first impacted the Atlantic coast of Brittany, downing and uprooting trees and damaging roofs across the area. In Fecamp, Normandy winds reached 175 kilometres per hour (109 mph), the highest in association with the storm. As of October 21, power electric utility Enedis reported over 250,000 households that are without electricity due to Aurore. Along Normandy, Champagne-Ardennes, Paris, and Île-de-France, train services were disrupted while an under-construction house in Plozévet, Finistère. Granville, Manche reported gusts of 143 kilometres per hour (89 mph) and Groix, Morbihan at 134 kilometres per hour (83 mph).^[1][2] Telephone lines were also affected and several bridges across the affected portion of the country were unpassable for vehicles or their lanes being closed.^[3] Flash floods also destroyed an unknown number of houses along Brittany.^[4]
