A fresh bout of wet and unsettled weather is heading for Wales this week, with the Met Office issuing a 24-hour yellow weather warning for rain. Forecasters are predicting widespread downpours and possible flooding.
The warning will be in force from 6am on Friday, November 14, until 6am on Saturday, November 15, covering several parts of Wales. From the early hours of Friday morning, weather maps show light rainfall spreading across much of Wales.
Coastal areas from Pembroke northwards may stay relatively dry at first, but as the rain band moves in from the west, conditions are expected to deteriorate quickly. By 7am, heavier rain will be falling over Swansea, Cardiff, Merthyr and Monmouth, gradually spreading inland through the morning.

By midday, forecasters expect 4–8mm of rain to blanket much of the country, stretching from Cardiff up to Aberystwyth, Newtown and Wrexham. Heavy rain will also impact Abergavenny, Hereford, Hay-on-Wye and Brecon, with localised flooding possible in low-lying areas.

Alun Attwood, duty tactical manager for Natural Resources Wales, warned that the combination of heavy rainfall and already saturated ground could lead to significant disruption.
He said: “The yellow rain warning in place from the early hours of Friday and into Saturday could lead to significant impacts across Wales. With rivers already swollen and the ground saturated, we expect to see flood alerts and warnings issued.”

He urged residents to take precautions and stay informed, saying: “We’re urging people to be vigilant and to make preparations for potential flooding now. You can check if you live in an area at risk of flooding on our website and sign up for our free flood warning service.”
Mr Attwood also reminded the public that *surface water flooding* was not covered by official flood warnings, and safety should remain the top priority.
“Keep away from swollen riverbanks and do not drive or walk through flood waters as you don’t know what lies beneath,” he stated.
“Keep an eye on weather forecasts and visit our website for the latest updates and practical advice on what to do before, during and after a flood.”
With conditions expected to remain wet into the weekend, residents are being encouraged to plan ahead, check local alerts, and take extra care when travelling.
