Met Offices issues a new yellow weather warning for rain in South Wales as the flood continues

Another period of persistent rain is expected to move across the UK on Sunday, threatening to cause further flooding in the wet areas of South Wales.

The Met Office has issued a yellow weather warning for the Cardiff area and Swansea north towards Llandrindod Wells and the A44.

It is slated to take effect at 3:00 am on Sunday and will last until 3:00 pm as the system moves from west to east across the country.

The weather warning comes into effect at 3:00 on Sunday

A widespread 20 to 40 mm of rain is expected with a minimum of 50 to 60 mm reaching some points in the mountains of South Wales.

According to forecasts, the rain “could be particularly persistent in central and south Wales, which contains currently saturated basins and highly sensitive to further precipitation”.

Floods of homes and businesses are possible as a result of the system, as well as delays in bus and train services.

Dan Suri, head of forecasts at the Met Office, said: “With further rain in the forecast for the next few days and the potential for another low pressure system early next week, further rainfall could create further challenges as the basins rivers are more likely to respond to extra rain more quickly.

“Floods, especially in areas already heavily affected, remain a possibility.”

Natural resources Wales labeled the “low risk” flood threat on Sunday, although one flood warning and three floods remain active.
