High waves could cause flooding in the Norfolk Broads region tomorrow, the Environment Agency has warned.
Officers from the authority are monitoring “tide locking” in the area at the moment.
Tide locking occurs when the raised sea level stops rivers from draining out to sea.
High tides are expected in the next few days due to a tidal surge coming down the East Coast, the agency said.
“The combination of these natural processes can lead to overtopping of defences and ultimately flooding,” it warned.
Current predictions suggest there could be some smaller impacts along the East Norfolk and Suffolk coast, including at Great Yarmouth and Lowestoft in the next few days.
People have been urged to be cautious and not to take risks on coastal paths and promenades.
