A number of flood alerts have been issued for the county including the Norfolk Broads.
Higher than usual tides are expected over the coming days due to the natural tide locking effect.
A spokesman for the Environment Agency said: "We expect to see high water levels around Potter Heigham, Wroxham boat yards and Ferry Road in Horning."
The areas covered by the flood alerts include Great Yarmouth, Gorleston, Aylsham and Wroxham.
People are being warned to take extra care when travelling on waterside roads and footpaths.
