Transport ground to a halt in some parts of the country on Saturday after more than a month's rainfall fell in less than a day.
The Environment Agency has reduced the number of flood warnings in England and Wales from more than 50 to 24, with 108 flood watches in force.
But severe weather warnings from the Met Office remain in place for much of Scotland amid concerns that milder weather and more rain could cause lying snow to melt and lead to flash floods.
The Environment Agency was forced to take emergency action to prevent flooding in the Thames Valley region because of the "very high" water level of the Thames.
Water from the Thames was diverted down the Jubilee River, a diversion channel, to protect Maidenhead, Eton and Windsor.
Flood risk manager Barry Russell said: "The rainfall over the past few days has resulted in very high levels in the River Thames.
"In order to protect the Windsor, Eton and Maidenhead area from flooding from the Thames we have put the Maidenhead, Windsor and Eton flood alleviation scheme into operation. We expect to continue operating the scheme over the next fewdays."
Around 5-10cm of snow fell over the highest parts of Scotland but most of that was soon melting.
On Saturday, an estimated 40mm of rain fell across some areas of western England - a month's rainfall in less than a day.
Among the worst hit areas were Bristol, Gloucestershire, Wiltshire and Somerset, where on Friday pupils at a village primary school were left marooned after a flooded road cut off access to the building.
