People are being told not to swim at some popular beaches because of pollution risks.
Visitors to Seaton Carew, Saltburn and Marske Sands in the North East have been advised not to swim in the sea due to high pollution levels.
Safer Seas Service's interactive map states that water quality is affected by "storm sewage" at Saltburn, Marks and Redcar Coatham, with the issue being caused by an overflow nearby.
