The Met Office has issued a yellow weather warning as more heavy rain is expected across the south of the UK.

The weather warning applies to most of southern England as far as Stoke-on-Trent and Sheffield, and to much of south and mid Wales.

Meteorologists warn that heavy rain showers are possible between 21:00 (BST) on Saturday and 18:00 (BST) on Sunday, potentially causing flooding and disruption.

“Given the amount of rain that has fallen recently in the south of the UK, this could lead to localised flooding,” said Nikki Berry, senior meteorologist at the BBC.

“However, there may be parts of the warning area where little to no rainfall occurs.”

According to Derek Brockway, senior meteorologist at BBC Wales, Victoria Park in Swansea received as much rain in 24 hours on Friday as it normally does in a month, making it the wettest place in the UK.

In some parts of south-east England, more than half of the rainfall expected for the whole of September fell in 24 hours on Thursday and Friday.

Goudhurst in Kent and Farnham in Surrey saw 29.4 mm (1.16 in) and 28.4 mm (1.12 in) respectively.

The yellow warning for rain applies to all of southern and central England up to South Yorkshire and all southern counties of Wales.

Areas of heavy, thundery rainfall are expected to spread first north and then west across England and Wales, according to the Met Office.

According to the Met Office, these areas of heavy rain could persist during the day in western areas on Sunday, while slow-moving heavy showers and thunderstorms are likely to develop further east.

There is a small chance that a few places within the warning area could see 80 to 100 mm (3.1 to 3.9 in) of rain by the end of Sunday.

These higher numbers are slightly more likely in the southern half of the warning area.

Meanwhile, 17 flood warnings have been issued in England by the Environment Agencywith Derbyshire and Nottinghamshire being particularly badly hit.

10 flood warnings have been issued in Wales.

The weather will be better further north as there will be long sunny and dry spells, but eventually it will become cloudier and milder.

Cooler and fresher temperatures are expected next week, but the outlook is generally uncertain.

Dan Harris, deputy chief meteorologist at the Met Office, said: “The weather forecast for later this weekend is reminiscent of this time last week and has greater uncertainties than average.

“This is due to a more complex than normal meteorological pattern, with multiple corridors of severe, locally active thunderstorms rotating around a slow-moving low-pressure area.”

Mr Harris added that people should stay up to date with weather forecasts as warnings are continually being evaluated.
