The Environment Agency has said residents living along the lower reaches of the River Thames in Surrey should remain prepared for further flooding as water levels continue to rise.
The Thames is expected to stop rising today, but it may be some days before the levels are back to normal, it said.
There is also an ongoing risk of flooding from the Rivers Parret in Somerset and the Severn in the Midlands. High groundwater levels mean we are likely to see continued flooding in areas such as the Somerset levels and moors, Dorset and Wiltshire.
Parts of Britain is set to be battered by flooding misery, as a band of rain is expected to arrive from the West this afternoon, the Met Office has said.
Helen Roberts, a forecaster from the agency added:
It'll be over south west England from midday and spread slowly eastwards across the rest of the country.
Monday night will see scattered showers in the West and into Tuesday morning but it will then be turning wet and windy on Wednesday and will be remaining unsettled.
There is a lot of saturated land and high river levels so any amount of rain is not good for those areas.
Further heavy rain today is expected to bring more misery to areas that have already seen widespread flooding.
Nearly 80 flood warnings remain in place throughout the country while there are more than 115 flood alerts, although none deemed severe - which would carry a danger to life.
River levels have been rising steadily in counties including Wiltshire, Hampshire, Dorset, Somerset and across the Midlands following days of downpours, the Environment Agency (EA) said.
Rivers including the Hampshire Avon through Wiltshire, Hampshire and Dorset, the Stour in Dorset, the Parrett in Somerset and the Severn through the Midlands showed little signs of receding.
Seventy-nine Flood warnings are still in place across England, mainly in the southeast and southwest.

A Rottweiler dog has been rescued from mud at Langstone Harbour by the Hayling Island and Portsmouth Coastguard Rescue Teams. The eight-year-old dog, Buddy, had become stuck up to his chest in mud whilst enjoying an afternoon stroll with his owner.
Steve Duff, Portsmouth Coastguard Sector Manager says:
"If you’re out walking with your dog near cliffs or areas that you suspect might be dangerous, it’s advisable to keep your dog on a lead.
"However, if your pet takes an unexpected deviation and gets into difficulty at the coast, please do not attempt to rescue it yourself but call 999 immediately and ask for the Coastguard. We have specialised equipment to ensure that your dog can be rescued safely without endangering you.”
The Environment Agency said those living along the lower reaches of the Thames in Surrey should remain prepared for further flooding this weekend as water levels continue to rise.
It said in a statement: "There is also an ongoing risk of flooding from the Rivers Parret in Somerset and the Severn in the Midlands. High groundwater levels mean we are likely to see continued flooding in areas such as the Somerset levels and moors, Dorset and Wiltshire."
But it said that water levels on the Thames between Lechlade, Gloucestershire, and Reading in Berkshire were beginning to slowly recede - while between Reading and Maidenhead they were stabilising.
The most recent estimates suggest that more than 700 properties have been flooded since the start of the year, but more than 239,000 properties have been protected by flood defences.
Photos taken today in Worcester show the extent of flood damage in the city after the River Severn burst its banks after several days of heavy rain.
As the clouds cleared, the blue skies made for picturesque views - but with footpaths, roads and fields still under water, the full cost of the damage has yet to be counted.
Further heavy rain is expected to bring more misery to areas that have already seen widespread flooding. There are 49 flood warnings in place in the South this afternoon. River levels have been rising steadily in counties including Wiltshire, Hampshire and Dorset following days of downpours.
Rivers including the Hampshire Avon through Wiltshire, Hampshire and Dorset and the Stour in Dorset showed little signs of receding. Communities along the River Thames throughout Surrey, Berkshire and Oxfordshire have also been warned that they are at risk of flooding.
Volunteers have been answering the call from the council to help clear Aberystwyth's seafront of shingle washed up by the recent stormy weather. Work to restore a 1920s shelter that was battered by waves is also being undertaken.
Up and down the coast of Ceredigion surveyors are assessing the damage caused to coastal defences and it's hoped a preliminary estimate on the costs of repairs will be completed by the end of the day. It's thought the total could be in excess of £1m.
