Londoners have filmed marble-sized hailstones pummelling cars and the streets around them as storms interrupted the record-breaking sunny heatwave.
Temperatures in the UK topped 34C for the sixth day in a row for the first time in nearly 60 years on Wednesday, with the highest reading of 34.6C in the capital.
The Met Office issued an ‘amber’ warning in Scotland after flooding submerged roads in the east, and stuck a yellow storm warning on all of England and Wales signalling potential floods and power cuts for the rest of the week.
Twickenham resident Al Jamieson filmed himself picking up one of the unusually large hailstones which landed outside his home in south-west London on Wednesday evening.
A Twitter user, Jaz Holgate, uploaded footage of similarly hefty chunks of ice battering her car windscreen a few miles away in Richmond.
It follows a pelting of hailstones so heavy they set off car alarms amid storms in the Welsh town of Capel Curig on Tuesday.
A Met Office extreme weather warning stayed in place across Wales into Wednesday night, with heavy storms in several counties.
People in Wrexham filmed intense lightning storms which arrived in the late evening – where it struck a home, blowing out a power socket and setting fire to a curtain.
Fire crews were also called to flooded homes in Rhayader, Powys, and minor flooding incidents in Wrexham and Llangollen, Denbighsire.
The Environment Agency’s Flood Duty Manager, Caroline Douglass, said: ‘Isolated flooding is also possible more widely across England until Thursday due to further heavy thunderstorms.’
‘Yellow’ warnings for severe thunderstorms remain in place across Wales, Northern Ireland and all regions in England except North Yorkshire and Tyneside until Monday.
More hail and lightning is expected in the South on Thursday.
The rain and thunder will bring a significant drop in temperatures with it, according to Met Office forecasters, although they will remain above average for this time of year over the coming days.
The mercury is not expected to fall below 25C in south-east England or below 21C in Wales until early next week.
Northern Ireland and eastern parts of Scotland are expected to enjoy the sunniest weather over the coming days, with Glasgow facing highs of 23C over the weekend compared to 18C in Edinburgh.
