At least one wildfire is reported to be out of control in northeast Spain due to winds gusting up to 55mph.
Three people have died due to the forest fires in the Catalonia region close to the border with France.
The area is a main link for holidaymakers travelling to and from southern France. Traffic on the cross-border AP-7 motorway was reported to have been severely disrupted yesterday.
A total of about 32,000 acres of forest are estimated to have been affected in the area, according to local authorities.
Two French people who died were among those trapped by fire as they travelled along the N-260 main coastal road near the town of Portbou and tried to reach the sea by climbing down cliffs, the BBC reported Catalan interior minister Felip Puig as saying.
