Western Europe was in the grip of a heatwave on Wednesday that claimed dozens of lives, disrupted power supplies, shut schools and cultural landmarks, as forecasters warned the extreme temperatures could persist until the end of the week. Smashing previous records, Britain logged its highest temperature for June, reaching 35.8 degrees Celsius (96.26 degrees Fahrenheit) in southern England as a heat dome hovered over much of Western Europe.

Spain reported two elderly people had died of heatstroke after days of temperatures exceeding 40 C, though conditions there began to ease on Wednesday following the hottest late-June days on record, according to national weather agency AEMET. Scorching temperatures killed hundreds of thousands of birds at poultry farms in Brittany and the Pays de la Loire, agricultural groups said. France's nuclear power plants, which supply most of the country's electricity, cut output by about 7% of total demand as high temperatures limited access to cooling water. Omega block traps extreme heat The heatwave is being driven by a weather pattern known as an Omega block, pushing temperatures as much as 18 C above normal, according to the Reuters Climate Monitor. The phenomenon resembles the shape of the Greek letter Omega, with a bulbous middle trapping in heat over regions for extended periods, with cooler weather on its fringes. Heatwaves and storms are being intensified by climate change. Britain's record reading followed only the second extreme heat warning ever issued. Hundreds of schools closed or shortened their day as officials warned that high temperatures could endanger even healthy people. The 35.8 C reported in the village of Wiggonholt in West Sussex edged above the previous June record of 35.6 C set in 1957 and matched in 1976.

The UK's meteorological office has issued an extremely rare red heat warning -- only issued once before -- for June 24 and 25, as temperatures could soar to 40C, unprecedented for the time of the year.

Weather agency Meteo-France has said the conditions are comparable to a heatwave in August 2003 that lasted 16 days and caused an estimated 80,000 excess deaths across Europe. Conditions in France were expected to remain stifling on Thursday, the forecaster said, extending a red alert weather warning to 72 districts across the country. Europe is warming at more than twice the global average, the World Meteorological Organisation has said, making prolonged heat episodes increasingly likely. Paris Fashion Week swelters The Eiffel Tower and the Louvre announced early closing times, and the Changing of the Guard outside Buckingham Palace was scaled back, without the usual ceremony of soldiers in scarlet tunics and heavy bearskin hats. The Uffizi Galleries in Florence, one of Italy's top tourist sites, halted ticket sales on Wednesday to fix an air conditioning malfunction. In Paris, where the annual Fashion Week was underway, the audience sweated through the Louis Vuitton show as male models showed off creations by pop singer Pharrell Williams on Tuesday evening. Labels, including Dior and Rick Owens, changed their schedules to hold shows in the morning. First-time visitors to the French capital were disappointed. "So many people who had travelled from around the world aren't getting the chance to see the sights that Paris has to offer because of this heatwave," said Tanya Thompson, a visitor from the United States.

An extreme heat warning was in place across the Netherlands, where outdoor sports were cancelled, public transport was scaled down, and schools shortened classes or closed as temperatures were expected to soar to 36 C. In Switzerland, local authorities opened air-conditioned theatres for free daytime cinema screenings. Work hours impacted Construction firms across the continent adjusted working hours to limit exposure, and retailers struggled to keep up with demand for fans and portable air conditioners. Europe has no unified rules governing work in extreme heat, with national regulations varying. A French agricultural cooperative said farmers had moved to night shifts to protect workers and reduce fire risk. Still, at the Vatican, tourists waited patiently in the blazing sun to visit museums on Wednesday. Some held umbrellas or fans, and many gathered for refills of water from fountains or cafes for other refreshments. "We want a beer, a beer for the heat," said Father Israel from the Dominican Republic as he held up a large pint of lager in his hand.
