The threat is caused by a combination of strong winds, rain, spring tides and a tidal surge with fears the combined effects will be too much for existing flood defences along the coast and along the tidal rivers that cut into the region from the sea.

Suffolk

There is a red flood warning - advising residents to expect flooding and to take immediate action - in place along the north and south banks of the Stour Estuary between Shotley Gate and Brantham,

High water is due at Harwich at 12.45pm on Friday, which is when the threat of flooding peaks.

The Environment Agency has said that properties at the bottom of Cattawade Street and Factory Lane in Brantham, those around the Mill pond and Holbrook Creek in Holbrook, plus Rose Farm Cottages at Shotley and waterside properties along the tidal Stour are most at risk.

Orange level flood alerts have been issued with flooding possible along the tidal River Deben estuary, including Woodbridge.

The same level of warning is in place in Felixstowe, and along the River Orwell estuary into the centre of town covering Ipswich Quay, Chelmondiston, Shotley and Woolverstone.

Higher up the coast, temporary barriers have been erected in Lowestoft to protect properties.

Essex

There is a high risk of significant flooding around lunchtime on Friday around the coast from Clacton to Lee Wick with high tide hitting Clacton at 1pm.

The combination of the high tide, rain and strong wind has led to the Environment Agency issuing a warning that the flood could pose danger to life.

West Mersea, The Strood and adjacent marshland is also affected by the warning.

In Jaywick, rest centres have been opened ahead of a planned evacuation. Essex County Council is providing assistance, shelter and buses for those at risk with vulnerable residents already being advised to leave their homes ahead of the full evacuation which starts at 7am tomorrow.

There is also a severe flood warning in place along the tidal River Stour with Mistley, the Quay and the Walls including. The threat is slightly lower in Manningtree

Residents in Harwich Town, Dovercourt, Bathside Bay and Walton-on-the-Naze have been warned to expect flooding, and advised to take immediate action.

Orange alerts cover the rest of the Essex coast from Kirby Cross to Clacton, and around Brightlingsea, Wivenhoe, East Mersea, Tollesbury and the Blackwater Estuary.
