The Met Office has issued two yellow weather warnings for heavy rain and strong winds on Friday and Saturday in the Anglia region.
The Met Office says a band of heavy rain followed by heavy showers or thunderstorms on Friday has the potential to bring disruption. Up to 30 mm of rain could fall in just a few hours.
A second weather warning has also been issued for the risk of strong winds gusting at 40 mph in the Anglia region during the day on Saturday.
"A band of heavy rain, with the possibility of some very heavy bursts, will move northwards during Thursday night and Friday. "Within this band 10-15 mm is widely expected, however some places could see as much as 30 mm in just a few hours. "Once the rain has cleared scattered showers and thunderstorms are expected to develop, particularly during Friday. "Many places will miss these, but where they do occur 10-20 mm is possible in one hour, with perhaps 30 mm in a few hours."
