The sweltering summer weather took a short break this weekend as extreme conditions hit parts of the country.
Lightning strikes, hail, torrential rain and flash flooding have had major effects on people across east and south-east England.
London Fire Brigade said that it was helping people trapped in their cars across parts of the capital, and one road was described as a 'river of hail'.
East Sussex Fire and Rescue Service said it had received around 300 calls within a few hours, while a further 60 calls were passed on to Cambridgeshire Fire and Rescue Service.
Brighton and Hove police have told people to not enter flood water on foot or in cars.
