Here are the main developments related to the wildfires raging in Spain and France on Tuesday:
The huge fire raging in France's southwestern region of Gironde has not progressed overnight, the prefecture said early Tuesday. "The burned area has not increased," it said.
Firefighters in Spain meanwhile made progress during a "positive night" against wildfires raging west of Madrid that have forced the evacuation of tens of thousands of people, Interior Minister Fernando Grande-Marlaska said Tuesday.
French President Emmanuel Macron, on a visit late Monday to a crisis centre in Bordeaux, that is threatened by a giant wildfire, said: "The coming weeks will be tough and we have to hold out."
He said a second major fire in the Landes region further south was now "contained" but remained a threat. The fire forced the evacuation of 30,000 people but authorities said 15,000 have been allowed to return.
Spain's AEMET meteorological agency officially declared a new heatwave would begin on Wednesday, lasting until the end of the week.
It earlier said temperatures would soar and humidity levels drop across Spain, causing the fire risk to "surge to very high or extreme levels across almost the entire country".
"This situation will persist, or may even worsen, in the following days," it added.
Temperatures are also predicted to rise again in France, which is battling two major fires on its Atlantic coast.
Reacting to the forecast, Spanish Prime Minister Pedro Sanchez said: "I ask for understanding and call on all citizens in all the country to exercise extreme caution and take every possible precaution."
"We face difficult hours, complex hours" ahead, he warned.
The European Union said it would deploy additional aircraft to Spain to help combat the fires, the bloc's crisis management chief told AFP.
"We currently have nine aerial assets deployed on site, and tomorrow we will have 11, drawn from our European strategic reserve," EU commissioner Hadja Lahbib said.
Several fires broke out in northern and central Portugal, with over 1,000 firefighters and other professionals fighting the flames, supported by around 20 planes and helicopters, civil protection services said.
