The windstorm Ciara affected large part of north-western Europe on 9 and 10 February.

Storm Ciara affected the UK on Sunday, 9th Feb. The main hazards were strong gusty winds which uprooted trees, damaged buildings, and disrupted transport. Energy companies said that 675,000 homes lost power during the storm. An amber warning of strong winds was in force over much of England and Wales. Wales was hit by some of the strongest winds, with 93 mph (~ 150 km/h, 41 m/s) recorded in Aberdaron, north-west Wales. Manchester Airport also recorded gusts of 86mph (138 km/h, 38 m/s). Overall, the highest gusts were measured in Wales and much of England - widely between 25 and 32 m/s. Storm Ciara brought heavy rain in some places such as Cumbria, NW England and Wales. This rain was orographically enhanced and substantial totals were recorded in 24 hours: Honister Pass, in Cumbria received 177 mm and few other places in that area reported 24h totals close to 100 mm.
