Spain on red alert: ‘Danger to life’ warning issued for first heatwave of summer as intense African heat dome sends temperatures soaring above 42C

A RARE red weather warning has been issued for northern Spain as western Europe braces for its first major heatwave of the summer.

State meteorological agency Aemet are urging locals and visitors in the normally-cool northern regions of Bizkaia and Gipuzkoa to take ‘extreme precautions’ this weekend, with temperatures expected to soar well above 40C.

The alert kicks in at 1pm on both Sunday and Monday and lasts until 9pm in the evening on both days, with forecasters warning of an ‘extraordinary danger’ to life.

Things are expected to get even hotter next week, with the global European ECMWF-AIFS predictive model suggesting localised temperatures could rocket to an extreme peak of 45C.
