There is a Met Office yellow weather warning in force for further heavy rain and thunderstorms across the Anglia region on Sunday.
The warning says: "Further heavy, thundery showers are likely to develop in some eastern parts of the UK today. Although many places within the warning area will stay dry, where storms do occur, torrential downpours are possible with lightning, hail and perhaps locally strong wind gusts. The most likely areas for local disruption are across parts of eastern and southeastern England."
The weather warning is valid until 11.55pm on Sunday 20 July 2014
"The remnants of the very warm, humid, unstable airmass are still affecting eastern and some central parts of the UK today. As a result, further thundery showers are likely to develop across these parts in response to daytime heating today. There remains some uncertainty regarding exactly where these may develop and, as often happens in this situation, some areas will stay dry."
