The heat wave searing western Europe is set to peak in the coming days, threatening power networks and triggering health alerts.

A high-pressure system combined with a stream of super-hot air from North Africa and abnormally warm oceans is baking the region from Portugal to the UK. On Sunday, Spain set a June heat record of 46C (114.8F) near El Granado in the south of the country, according to preliminary data from forecaster AEMET.
