Hurricane Vince was one of the most unusual hurricanes ever to develop in the Atlantic basin, forming in October during the 2005 Atlantic hurricane season. Vince was the 20th named tropical cyclone and twelfth hurricane of the extremely active season.
Vince developed from a non-tropical system on October 8, becoming a subtropical storm southeast of the Azores. The National Hurricane Center did not officially name the storm until the next day, shortly before Vince briefly became a hurricane. Vince then made an unprecedented landfall on the Iberian Peninsula on October 11 as a tropical depression, dissipating over Spain.
