Heavy rainfall from Storm Claudia has led to some flooding in parts of North Wales, with low-lying areas and roads affected.
Natural Resources Wales (NRW) issued multiple flood alerts on Friday and Saturday, warning residents to prepare for potential impacts as rivers swelled and surface water accumulated amid saturated ground conditions.
The storm, named by the Met Office, brought intense bands of rain across Wales and England, with a yellow weather warning in effect from 6am Friday to 6am Saturday.
In the region, areas such as Gwynedd faced disruption, including flooding on the A5 near Bethesda, where motorists were urged to exercise caution or avoid the route altogether. Live updates from local media highlighted ongoing flooding of low-lying land and roads, with adverse weather persisting through Friday.
NRW reported 10 flood warnings—indicating flooding is expected—and 33 flood alerts across Wales as of late Friday, with slow-responding rivers likely to continue rising overnight.
“People are being urged to be vigilant and prepared this Friday and into Saturday as Storm Claudia brings heavy rainfall that will lead to flooding and disruption in Wales,” stated a NRW advisory.
NRW emphasised the risk due to already saturated soil from recent unsettled weather, noting that further heavy rain could exacerbate conditions.
In Conwy and Denbighshire, flood alerts were in force as North Wales braced for torrential downpours, with reports of surface water affecting travel. On Saturday, the Conwy Valley train line suspended its service between Llanrwst and Blaenau Ffestiniog and instead provided bus travel due to flooding on the route.
Social media and local news outlets captured the scene, with one update describing the weather as “winter weather” but cautioning against underestimating its severity.
While the most severe impacts, including a major incident declaration, were reported in South Wales—such as Monmouth, where “severe and widespread” flooding prompted emergency responses—the northern regions experienced notable disruptions.
Rainfall totals reached up to 100mm in parts of Wales, contributing to 80 flood warnings nationwide by Friday evening, with expectations of continued flooding ahead of a forecasted cold snap.
Authorities advised residents in at-risk areas to stay alert and monitor updates from NRW and the Met Office.
As of early Saturday, no major incidents were reported in North Wales, but clean-up efforts are anticipated as the storm’s effects linger. The Met Office warned that the combination of heavy rain and gusty winds could lead to further issues, urging caution.
