More than 100 flood warnings have been issued by the Environment Agency as more heavy rain is forecast for Monday.
The agency had issued 104 flood warnings across England by 1pm on Monday, while a further two are in place in Scotland, according to the Scottish Environment Protection Agency (SEPA).
There were also 177 flood alerts, plus five in Wales and four in Scotland. A flood warning means flooding is expected, and an alert means flooding is possible.
The agency said on its website that "local inland flooding is probable for the South and West of England on Monday, and possible on Tuesday. Local inland flooding is possible more widely until Wednesday.
"Land, roads and properties could flood and there could be travel disruption," it warned.
A yellow weather warning is already in place for large parts of southern England and South Wales, and lasts from 12pm on Monday to midnight. Up to 30mm of rain is predicted to fall in some places.
Affected areas include Hampshire, the Isle of Wight, Portsmouth, Southampton and West Sussex.
In southwest England, areas include Cornwall, Devon, and Dorset, with Cardiff, Swansea and Newport among affected areas in Wales.

The Met Office said: "Bands of rain and heavy showers will move east across southern parts of England and Wales during Monday afternoon and evening."
It added: "10-15mm of rain is likely fairly widely with 20-30mm in some places exposed to the strong south to southeasterly winds."
The warning forecasts spray and flooding on roads "probably making journey times longer".
Bus and train services will probably be impacted with flooding of a few homes and businesses possible, it added.
There will also be a chance of some interruption to power supplies and other services, it continued.
The Met Office said on Thursday that rain had fallen every day of 2026 so far in southwest England and South Wales.
There has been 50% more rainfall than usual in both, the forecaster added.
Both have experienced a far wetter than average January.

Met Office meteorologist Tom Morgan said Monday's weather would be "much the same, with further spells of rain". The most persistent outbursts would be in the "far northeast of Scotland, especially Orkney and Shetland".
Mr Morgan warned that "outbreaks of fairly heavy rain [will be] pushing into Wales and the South West. Rain could lead to some flooding in places".
Brisk south easterly winds will bring "large waves in places along the south coast".
The brightest weather will be across the Midlands and parts of the South East, which "should brighten up nicely by this afternoon and in any sunshine it will feel fairly mild for the time of year".
