Hurricane Vince's impressive organization was very short lived as westerly wind shear began to erode the eye within hours. In response, the storm weakened to a tropical storm shortly thereafter. A broad low-level trough approached the storm from the northwest, pulling the convection northward as the storm's low-level center accelerated eastward. On 10 October, two brief bursts of convection surprised forecasters, but with the sea surface temperature as low as , the flares were not sustained. 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. The fast-moving tropical depression quickly dissipated over land. Its remnants moved across southern Spain, dumping rain on the drought-ridden region, and moved into the Mediterranean Sea south of Alicante in the early hours of 12 October.
