The Environment Agency (EA) is urging communities along the River Thames to remain vigilant and be prepared to take action as further flooding is expected.
Across the South East there are currently 52 flood warnings in place, and 96 flood alerts.
More rain is expected tonight and tomorrow.
Water levels in the River Thames continue to rise and communities are being urged to make sure they know what they will do if flooding occurs, to check on elderly neighbours and make sure they move valuables upstairs in case their property does get flooded.
Simon Hughes, regional duty manager for the EA, said: "I would urge communities not to delay in taking action, particularly along the River Thames below Oxford, into Berkshire and through Surrey.
"Levels are high and will continue to rise for the next few days and, while our staff are working hard to provide up-to-the-minute information for the public, local authorities and emergency services, people need to start taking action now.
"It is important to take extra care in deep or flowing water; do not take risks if you are unsure of the depth of the water or of any hidden hazards."
The EA continues to operate flood defences across the region, such as the Jubilee River.
Teams continue to work around the clock checking and maintaining flood defences, clearing blockages in watercourses, deploying temporary defences, monitoring water levels and issuing flood warnings where necessary.
