 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 October 10 , two brief bursts of convection surprised forecasters , but with the sea surface temperature as low as 22 ° C ( 72 ° F ) , the flares were not sustained . Vince continued to weaken as it approached the Iberian Peninsula and became a tropical depression on October 11 , 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 October 12 .
