Wales is warning residents to prepare for a significant rise in flood risk during autumn. Source: bbc.co.uk.
What Happened
Natural Resources Wales (NRW) has issued a ‘prepare for the unthinkable’ alert over the coming months.
The warning follows long-range weather forecasts predicting wetter, windier conditions than usual.
Residents in flood-prone areas, including Monmouth and Cardigan, say they are increasingly worried.
Key Facts
- One in seven properties in Wales is at risk of flooding.
- More than 274,500 homes and businesses are currently classified at risk.
- Only 27% of eligible residents are signed up to receive flood warnings via phone or email.
- Wales has seen major floods in recent years, including storms Dennis (2020), Bert and Darragh (2024), and Claudia (2025).
- Climate change and the El Niño event are contributing to more intense weather extremes.
Background: How Floods Happen in Wales
Floods in Wales come from two main sources: river overflow and sea-level rise.
Fast-responding rivers, especially in the south Wales valleys, fill quickly due to steep terrain and heavy rainfall.
Surface water flooding — when local drainage systems are overwhelmed — is becoming a growing concern.
Coastal areas face tidal flooding, especially during strong south-westerly winds and high tides.
Why It Matters
Residents have lived through devastating floods before.
Malcolm Butcher, 82, of Monmouth, said he never saw flooding like what happened in November 2025.
He recalled: ‘At 2:30 in the morning when it hit it was unbelievable… absolutely raging.’
Eighteen cars were lost on his street, including his own. Houses behind were completely flooded.
Residents say they now understand the danger — and the need to act.
Community Action
Local leaders and businesses are taking steps to prepare.
Jane Roche, who runs a café and fishmongers on the River Teifi, helped create a community flood plan.
She said: ‘Flooding is something we’ve learned to live alongside. A community plan brings people together and builds confidence during warnings.’
Cardigan’s mayor, Olwen Davies, has installed a flood door and uses a flood gate for extra protection.
What to Watch Next
NRW advises people to:
- Check their flood risk by postcode online.
- Sign up for flood warnings via phone or email.
- Access advice on what to do if a flood warning is issued.
Weather patterns can change quickly at this time of year, and long-range forecasts describe broad seasonal trends rather than the timing, location and severity of individual weather events.
Jeremy Parr of NRW said: ‘You can’t stop all of the flooding all of the time. So people need to think about what they would do if their area flooded.’
He added: ‘Time and time again, people say they’d never flooded before — and didn’t think it would happen to them.’
NRW’s flood warning service covers 181,158 properties, but only 48,844 are currently signed up.
Some residents say they are hesitant to sign up, fearing it might affect insurance premiums — a concern NRW has not confirmed.

Residents are urged to take action now — before the next storm hits.
