A huge clean-up operation is now under way after downpours caused widespread devastation.
Forecasters have predicted clearer weather across the UK - but there are fears temperatures are predicted to fall below freezing in many parts.
The Environment Agency (EA) warned some rivers could still rise on Thursday, and it could take much longer for floodwaters to subside, while around 140 flood warnings remain in place in England and Wales, with a similar number of flood alerts still active.
An Environment Agency spokesman said: "Large rivers such as the Thames, Trent and Severn are still rising or remain at very high levels, and teams from the Environment Agency continue to work around the clock to shore up defences, monitor river levels and clear blockages from watercourses. People who live along these rivers should keep up to date with the latest situation from the Environment Agency website, and sign up to free flood warnings."
EA figures showed some 1,600 properties had flooded since Wednesday, while flood defences had protected more than 54,000 homes.
In Whitby, North Yorkshire, preparations were being made to demolish Aelfleda Terrace, which slipped 30ft after torrential rain caused subsidence. One resident, Jude Knight, told ITV Calendar News: "I'm just devastated, I've lost everything."
Eastern England could still experience some rain on Thursday, but Rachel Vince, a forecaster with Meteogroup, said it would not be persistent. "The picture at the moment is we have got a lot of cloud across central southern and south eastern England," she said. "A lot of places have stayed dry. We've got showers affecting eastern Britain, like Yorkshire, Lincolnshire, East Anglia, and the South East, and up to Northumberland and eastern Scotland.
"Looking at the western half of the UK, it has been predominantly dry, with some spells of sunshine. It looks like it has been a glorious day for many areas, so that should help with any flooding issues."
But cold weather from the north could lead to flooded areas turning icy, with the forecaster warning: "It's turning into a chilly spell. For people out and about first thing in the morning, there could be ice on any untreated surfaces from this week's rain."
Prime Minister David Cameron led tributes to the emergency services and "good neighbours" who have helped tackle the flooding across England and Wales.
