More rain is forecast throughout Britain early this week, although the risk of flooding is much lower than at the weekend when storms killed at least six people and forced hundreds from their homes, authorities said.
It has been the wettest summer in Britain since records began in 1914, according to the Met Office.
The Environment Agency said many flood warnings across England and Wales were being downgraded as the threat from swollen rivers eased.
"River levels are slowly starting to come down, so we're expecting the general situation to improve significantly over the next 48 hours," an agency spokesman said. "We are not expecting any more severe flood warnings to be issued."
The Met Office forecast a day of sunny spells and some rain, although the showers will be nothing like the downpours that lashed Britain at the weekend.
Rivers burst their banks, houses were flooded and drivers faced dangerous conditions on the roads as a month's rain fell in 24 hours in some regions.
