The number of flood warnings reached more than 75 in England, as more than a month's worth of rain poured down on the UK within 24 hours.
The Met Office warned southwest England will experience the most severe rainpour, and The Environment Agency said 94 homes had been flooded in England and Wales, as BBC News writes.
The agency added surface water flooding occurs when drains become overwhelmed by too much rain, the Guardian writes. The public have been warned not to risk walking through flooded areas.
In Northern Ireland "there is no flood warning system but the Met Office has issued a yellow warning - urging people to be aware - for its south-eastern tip," BBC News writes.
Officials at Silverstone on the Northamptonshire/Buckinghamshire border had to turn away thousands of fans hoping to check out the Formula 1 Grand Prix qualifying sessions on Saturday because of muddy conditions in its car parks, BBC News published.
Flooding also caused delays and cancellations on the railways, with problems noted in Manchester, Yorkshire, Derbyshire, Lincolnshire and Nottinghamshire, the Telegraph writes. "There is no immediate end in sight to the wash-out summer, with meteorologists warning that Britain is very unlikely to see a long spell of hot, sunny weather during the Olympics," the Telegraph adds.
