The Environment Agency is warning that river levels are continuing to rise despite the improving weather outlook.
The Agency said rivers are continuing to respond to recent rainfall meaning that there is a continued risk of flooding in parts of southern and central England over the next few days.
The EA currently has 50 flood warnings in place where flooding is expected and immediate action is required, together with a further 128 flood alerts where flooding is possible warning people to be prepared.
There is an increased risk of localised river flooding in the south east of England, along lower parts of the River Severn and in East Riding of Yorkshire. The Agency said lland, roads and some properties are expected to flood and there will also be travel disruption.
High groundwater levels in parts of southern England and in north Lincolnshire means there is a risk of groundwater flooding. Local groundwater flooding is expected in parts of Dorset, Wiltshire, Hampshire, West and East Sussex and Brighton for at least the next five days.
The Agency is also warning that local coastal/tidal flooding is possible but not expected for parts of the English Channel coast on Thursday.
According to the UK Met Office, the country has already reached 90% of the normal rainfall level for December, while monthly rainfall records in South Yorkshire, Nottingham and Lincolnshire have already been broken.
