Description

Hurricane Leslie was the strongest cyclone of tropical origin to strike the Iberian Peninsula since 1842. A large, long-lived, and very erratic tropical cyclone, Leslie was the twelfth named storm and sixth hurricane of the 2018 Atlantic hurricane season. The storm had a non-tropical origin, developing from an extratropical cyclone that was situated over the northern Atlantic on 22 September. The low quickly acquired subtropical characteristics and was classified as Subtropical Storm Leslie on the following day. The cyclone meandered over the northern Atlantic and gradually weakened, before merging with a frontal system on 25 September, which later intensified into a powerful hurricane-force extratropical low over the northern Atlantic.
