A heat wave will bake western Europe in conditions as much as 10C above the norm in the coming days, threatening harvests, stressing power systems and triggering health alerts.

The region around Seville in southern Spain is forecast to reach 42C (107.6F) through the weekend. The French Mediterranean coast will test 40C on Saturday, with similar temperatures expected in southern Italy and Sardinia. Highs in London could touch 35C on Monday. Some areas won’t cool below 25C overnight, increasing health risks.
