The new alerts are in place for the Suffolk coast from Felixstowe including Orwell and Stour estuaries, and the tidal Deben estuary.
Areas likely to be affected by possible flooding includes the waterfront at Pin Mill, The Strand at Wherstead, under the Orwell Bridge, Felixstowe Ferry, Woodbridge and Waldringfield.
The agency says the flood gates at Felixstowe seafront will be closed.

A spokesman for the Environment Agency said: "This message has been issued because some minor flooding to coastal roads and footpaths is likely.
"The current series of high spring tides has now reached its peak and will fall away over the next few days.
"Take care on coastal roads and footpaths, and don't put yourself in unnecessary danger."
Flood alerts for groundwater flooding in Bury St Edmunds and Newmarket remain in place.
