Weather: 'Dry and sunny' for Scotland while electric storms threaten England and Wales
Heavy rain and thunderstorms will batter parts of the UK in the coming days amid a spell of tropical and muggy weather.
Showers moving in from the Atlantic will lash southern and eastern areas of the country on Sunday, which will also be hot and humid.
Forecasters say the “tropical” conditions will continue until Wednesday, with temperatures climbing into the high twenties.
Greg Dewhurst, a Met Office forecaster, said: “A changeable picture will emerge over the coming days with it being on the warm and humid side for many.
“It will be warm and muggy and there will be plenty of cloud as high pressure builds on Monday, the day starting sunny and dry before turning wet and windy in north-eastern and western parts of the UK.”
Temperatures in London and the South East could then push as high as 29C on Tuesday, before turning sunnier and cooler from the middle of the week.
Mr Dewhurst added that an area of “tropical maritime air” moving in from the south west will hang over the UK over the coming days.
Another forecaster earlier told PA an “odd rumble of thunder may be heard in isolated areas”.
