As much of Britain continues to bask in sweltering temperatures, lightning storms have also begun to strike.
This dramatic display was caught on camera as Scotland was battered by thunderstorms shortly before midnight on Tuesday.
Torrential rain also caused flooding and travel disruption, with more downpours and storms predicted in parts of Northern Ireland, England and Wales from Wednesday afternoon.
The Met Office has warned of potential damage to buildings from lightning strikes or strong winds and a chance of travel disruption due to flooding.
It also warns of 30 to 40mm of rain falling in less than an hour in some places.
But the heatwave in southern England is set to continue, with London and the South East expecting temperatures of up to 36C (96.8F) on Wednesday.
