COMMUNITIES across South and West Wales faced severe flooding overnight after hours of relentless rainfall left roads impassable, rivers bursting their banks, and emergency services stretched to the limit.
Natural Resources Wales (NRW) issued multiple flood warnings and alerts on Tuesday evening (Nov 4) as heavy rain swept across the region, continuing into the early hours of Wednesday (Nov 5). Areas of Carmarthenshire, Pembrokeshire, Ceredigion, and parts of Swansea and Neath Port Talbot were among the worst affected.
In Pembrokeshire, council teams worked through the night to deal with flooding in Pembroke, Wisemans Bridge, Haverfordwest, and Crymych. Roads were closed as surface water, debris, and mud made conditions treacherous. The Commons in Pembroke and nearby Bowett Woods were both severely affected, with cars becoming stranded in rising water.
In Carmarthenshire, properties and roads were flooded in Llandovery, Ammanford, and across the Tywi Valley. Plaid Cymru MS Adam Price called on the Welsh Government to provide immediate support for flood victims, paying tribute to the “heroic efforts” of local authority staff and emergency responders who worked overnight to rescue vulnerable residents.
Further east, Swansea and Neath Port Talbot saw widespread surface water flooding, with commuters facing disruption on major routes including the M4 and A465 Heads of the Valleys Road. Bus and train services were delayed or cancelled due to standing water and debris on the lines.
NRW said the combination of high tides, saturated ground, and prolonged downpours created “perfect storm” conditions, overwhelming drainage systems across the region.
A spokesperson for Dyfed-Powys Police urged drivers to take extra care and avoid unnecessary travel: “We’ve seen multiple reports of stranded vehicles and road closures. Please obey road closure signs and never attempt to drive through flood water — it can be deeper and faster-moving than it appears.”
While conditions began to ease by Wednesday afternoon, clean-up operations are expected to continue for several days, with councils warning that further rainfall later in the week could hamper recovery efforts.
Residents are being urged to check the latest flood alerts via the NRW website and follow local authority social media channels for updates on road closures and safety advice.
