Great Yarmouth has been divided into three zones for prioritisation of evacuation.

Officers are on the ground knocking on doors giving advice to householders to leave their homes and to stay with family and friends outside the borough. If this is not possible, then residents are being advised to move upstairs and make safe their valuables.

The Environment Agency map showing the flood risk areas is the predicted extent of high water if flood defences are breached affecting potentially around 7,500 homes. It is these areas that are being prioritised for police attention and self-evacuation.

Police are urging members of the public to stay away from the high risk areas and particularly the area close to the River Yare. Members of the public are also advised to contact emergency services only in emergencies.
