On 5 October, 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.

[1] 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.

[4] Hurricane Vince's impressive organization was very short lived as westerly wind shear began to erode the eye within hours.

[8][9] Vince continued to weaken as it approached the Iberian Peninsula and became a tropical depression on 11 October, shortly before it made landfall near Huelva, Spain.

[11] Spain's population, which had been battling fires after a record breaking summer drought, welcomed the rains brought by Vince's remnants.

[12] In two days the storm brought more rain to the province of A Coruña than had fallen all summer, easing the sinking water levels in provincial reservoirs,[11] but also causing traffic jams and minor floods.

Municipal roadworks on La Ronda de Poniente, a major traffic artery connecting the city to nearby motorways, were flooded and partially destroyed.

[1] Historical documents, however, suggest that a possibly stronger tropical storm or hurricane struck the Iberian Peninsula on 29 October 1842.

When Vince formed on 8 October it marked the first time in recorded history that a 21st tropical or subtropical storm had ever developed within a single Atlantic hurricane season.
