Extreme heat warning in parts of England, Wales

A four-day extreme heat warning came into force in parts of England and Wales on Thursday, with temperatures poised to exceed 35 degree Celsius in another heatwave that could pressure water supplies and transport services.

The Met Office said its amber warning, its second-most severe after red, will last until the end of Sunday, and warned that people vulnerable to extreme heat could face adverse health effects.

The temperatures are expected to peak at 35 degree Celsius on Friday and may hit 36 degree Celsius in some places on Saturday.

Much of England and Wales, plus eastern parts of Northern Ireland and Scotland, are predicted to be sunny and hot or very hot on Thursday, according to the Met Office's website.

The warning follows the driest July for England since 1935 when temperatures rose above 40 degree Celsius for the first time, turning a renewed spotlight on the impacts of climate change.
