The Environment Agency has predicted that water levels along some coasts of the UK could rise above those seen during the storm surge of 1953.
In that year, hundreds of people living on the east coast of the UK died in some of the worst storms ever recorded. More than 100 people died on Canvey Island in the Thames Estuary.
Improved flood defences mean that the impact is likely to be much smaller today, but people living in coastal areas are advised to monitor the Environment Agency website.
