A Met Office yellow warning was in place from 15:00 on Thursday into early Friday morning for thunderstorms and possible travel delays, flash flooding, and power cuts.

Is the heatwave caused by climate change?

While extreme weather events like heatwaves occur naturally, "research shows that with climate change they are likely to become more common, perhaps occurring as regularly as every other year", the Met Office says.

It conducted a study last year that found that the UK was now 30 times more likely to experience heatwaves compared with the year 1750, because of "the higher concentration of carbon dioxide (a greenhouse gas) in the atmosphere".

Records going back to the late 19th Century show that the average temperature of the Earth's surface has increased by about one degree since industrialisation.

A climatology institute in Potsdam, Germany, says Europe's five hottest summers since 1500 have all been in the 21st Century.

Scientists are concerned that rapid warming linked to use of fossil fuels has serious implications for the stability of the planet's climate.

Why is it so hot and is climate change to blame?

Meanwhile the dangers of cooling off in lakes, rivers and the sea were highlighted after six youths were rescued from the River Dee in Aberdeenshire after getting into difficulty.

Scottish Fire and Rescue Service teams from Aberdeen and Dundee were called out to Potarch Bridge just after 20:30 on Wednesday after water levels rose, leaving the youths unable to get back to shore.

The teams used an inflatable rescue sled to bring them to safety by about 22:15.

Network Rail Scotland urged passengers to stay hydrated while travelling on trains, reminding them that there are free drinking fountains at Waverley and Glasgow Central Stations.

And passengers travelling by train to Glasgow and Edinburgh from London faced delays, which were attributed to heat-related incidents in the south of England.

London North Eastern Railway, which operates the East Coast Main Line franchise, advised customers against travel for the rest of the day as record high temperatures caused "several incidents" on the East Coast route.

This included problems with infrastructure in the Peterborough area which led to LNER services in and out of London King's Cross being cancelled.

The Rail Delivery Group, which represents train operators and Network Rail, warned problems on the railways could continue until the weekend.

The Scottish SPCA also tweeted warnings asking people to reconsider leaving their dog in the car while they are out and about.
