Volkswacht Bodensee - Wildfires spread across heatwave-hit Europe

Temperatures soared in Greece, Spain and Portugal, while the heatwave was expected to continue in Britain and France into next week.

It is the second heatwave to hit the region in a matter of weeks, as scientists say they are becoming more frequent and intense due to climate change.

Southern Spain was bracing for temperatures to rise again Thursday as the stifling heat continued.

"For Thursday, we expect it to be the hottest day of this heatwave," said Spain's state meteorological agency AEMET.

The valleys around three major rivers -- the Guadiana, Guadalquivir and Tagus -- will experience temperatures of 44 Celsius (111 Fahrenheit) to 45 Celsius, it said.

The health ministry told people to drink plenty of fluids, wear light clothes and stay in the shade or air-conditioning.

The city of Almonte in the southern region of Andalusia saw the mercury hit 45.6 degrees Celsius at 5:30 pm on Wednesday.

Several other southern cities such as Seville and Cordoba recorded temperatures above 44C.

- 'Major' fires -

A fire in Spain which started in the eastern region of Extremadura on Monday has so far ravaged at least 4,000 hectares of land, local officials said.

Between January 1 and July 3, more than 70,300 hectares of forest went up in smoke in Spain, the government said -- almost double the average of the past 10 years.

Italy, Croatia, France and Portugal all reported forest fires linked to the heat this week.

In Greece, a helicopter helping to fight a forest fire on the island of Samos on Wednesday crashed into the Aegean Sea, killing two crew members, the coastguard said Thursday.

In Portugal, over 2,000 firefighters were battling dozens of wildfires across Portugal, including four deemed "major".

One person died in a forest blaze, authorities said Wednesday, after a body was found in a burned area in the northern region of Aveiro.

Around 60 others have been injured, some 860 people evacuated and roughly 60 homes destroyed or damaged.

Portuguese Prime Minister Antonio Costa warned that Thursday would be the "most serious" day of the heat wave because temperatures were expected to rise and winds were stronger.

"Today is the day where we have to be the most careful," he said.

- Fireworks cancelled -

Meteorological services in France also warned the situation would "become intense between Sunday and Tuesday" -- possibly exceeding 40C before dipping by Wednesday.

Although temperatures eased by a few degrees Celsius across France, wildfires continued in the Gironde region near the southwestern city of Bordeaux, destroying some 3,700 hectares of forest in three days, with firefighters still unable Thursday to stop the blazes.

Tourist magnet the Dune de Pilat, Europe's highest sand dune, was closed to visitors after several thousands were evacuated from campsites this week.

"The situation is stable, but not yet under control," the region's authorities said Thursday as temperatures were forecast to hit 38C.

However, no additional evacuation of residents was planned, after hundreds were moved from their homes in recent days as a precaution in the region.

Further south, the Landes region and the city of Nimes cancelled all fireworks for Bastille Day, France's national holiday.

Temperatures were expected to reach 36C in southern France, 25C in the north of the country, and 32C in Paris on Thursday.

London mayor Sadiq Khan announced an emergency plan to help homeless people deal with the extreme heat which includes distributing water and suntan lotion.
