Spain's meteorological agency is warning people to brace for high temperatures across much of the country over coming days.

The agency said Saturday that "temperatures will be significantly higher in much of the peninsula and the Balearic Islands," exceeding 35 degrees Celsius (95 F) and reaching 40 C (104 F) in much of the southern and eastern parts of the country.

The forecast predicted some respite in the form of showers and thunderstorms on July 10-11.

Last week, weather stations across Spain warned people to take extra precautions because high temperatures increase the risk of devastating wildfires.

Across the border, Portugal is also braced for fires after an exceptionally dry winter and the hottest and driest June for 12 years. Almost 54 percent of mainland Portugal is enduring severe drought.
