Hurricane Vince was an unusual hurricane that developed in the northeastern Atlantic basin. Forming in October during the 2005 Atlantic hurricane season, it strengthened over waters thought to be too cold for tropical development. Vince was the twentieth named tropical cyclone and twelfth hurricane of the extremely active season.
Vince developed from an extratropical system on October 8, becoming a subtropical storm southeast of the Azores. The National Hurricane Center (NHC) did not officially name the storm until the next day, shortly before Vince became a hurricane. The storm weakened at sea and made landfall on the Iberian Peninsula as a tropical depression on October 11. Vince was the first tropical system to do so since the 1842 Spain hurricane. It dissipated over Spain, bringing much needed rain to the region, and its remnants passed into the Mediterranean Sea.
On October 5, an operationally unnamed subtropical storm which had gone unnoticed by the NHC was absorbed by a temperate frontal low, which was moving to the southeast over the Azores. The low pressure system gained a more concentrated circulation and lost its frontal structure after absorbing the subtropical storm. The developing system became a subtropical storm itself early on October 8, 580 miles (930 km) southeast of Lajes in the Azores. However, the NHC decided not to name the system Vince at the time, because the water temperature was too low for normal development for a tropical cyclone. The storm gradually gained the tropical characteristics of symmetry and a warm inner core and became a tropical storm the next day. Its transformation to a tropical system occurred over water cooler than 24 °C (75 °F), much colder than the 26.5 °C (80 °F) usually required for tropical development.
