Findings of tornado site investigations undertaken following damage during Storm Ciarán on 1–2 November 2023

Abstract

AbstractOn 1‐2 November 2023, Storm Ciarán impacted the British Isles, causing widespread wind damage and significant disruption to the Channel Islands and parts of southern England. Three areas within this wider swathe ‐ Jersey (Channel Islands), Loders in Dorset and Sompting/Lancing in West Sussex ‐ suffered additional, more severe, localised wind damage. These areas were investigated by the Tornado and Storm Research Organisation (TORRO). Each of these sites was found to have been affected by a tornado. The most intense of these was in Jersey, where one of the strongest tornadoes in the UK and Channel Islands since 1954 occurred.
