Spain is set to enter its third heatwave of the summer on Tuesday, with temperatures forecast to climb above 40C across large parts of the country, the national weather office said.
The heatwave will be fuelled by a persistent area of high pressure that will trap hot, dry air from North Africa over Spain for several days, pushing temperatures to exceptionally high levels, AEMET said in a statement.
The heat is expected to intensify through Thursday, which forecasters say is likely to be the peak of the event, with some isolated areas potentially exceeding 45C.
"The level of danger will be significant during the central hours of the day, especially for outdoor activities and vulnerable people," the weather agency said.
Spain has already endured two other heatwaves this summer -- one in late June that broke temperature records across Europe, and another in early July.
