With one in seven properties in Wales currently classed as being at risk, officials are warning that conditions can change rapidly following a summer characterized by drought and wildfires.
Rising Seasonal Risks
The warning, which was recorded by the Global Incident Tracker on Sunday, 11 October 2026, at 20:51 UTC, highlights a heightened risk of wetter and windier weather throughout the coming months. Jeremy Parr of NRW stated that the organization is concerned by long-range forecasts, noting that the threat arises from both the sea and rivers, as well as surface water flooding where local drainage systems become overwhelmed. The agency has urged people not to become complacent
regarding these potential weather disruptions.
Despite the persistent threat, only 27% of those eligible to receive official flood warnings via phone or email are currently registered. Jeremy Parr emphasized that understanding your specific flood risk, signing up for alerts, and having a prepared plan can make a significant difference. The agency advises that people should check their flood risk by postcode online and access official advice on how to respond if flooding is forecast in their area.
Monmouth Residents Describe Unprecedented November Flood Damage
Wales has experienced a series of major flooding events in recent years, often following powerful storms such as Dennis in 2020, Bert and Darragh in 2024, and Claudia in 2025. In the town of Monmouth, residents described the November 2025 flooding as harrowing
and dreadful.
Long-time residents Malcolm Butcher, Jim Tyler, Brian Churches, and Dave Blake recalled the event, stating they had lived in the town all their lives and never seen anything like it.
“At 2:30 in the morning when it hit it was unbelievable… absolutely raging. If it had happened in the daytime people would have died.”

The impact of that event was severe, with eighteen cars lost on a single road and numerous homes flooded. Imogen Elliot, another resident, recalled that the water reached four feet deep at a local store and surged up the street. She noted that while the town has experienced flooding previously, the recent event was unprecedented, adding, It’s not back to normal yet but we’re getting there.
Officials Urge Residents to Prepare for Unexpected Flooding
NRW officials suggest that residents can help mitigate the impact of floods by moving valuable items to higher floors and keeping sandbags on hand. Jeremy Parr noted that the organization is repeatedly told by those who have experienced devastating flooding that they had never flooded before and did not believe it would happen to them. He emphasized that residents should think the unthinkable really – or the unpleasant – and [consider] if it were to flood around where I live, what would I do?
The Global Incident Tracker, which classified this event as a minor flood incident, provides general safety guidance for such situations. This includes never walking or driving through floodwater, as 15 cm of moving water can knock a person down and 60 cm can float a car. The guidance also recommends moving to higher ground early, switching off electricity at the mains if water enters the building, and treating all floodwater as contaminated. The tracker notes that while it monitors these events through media reports, its ratings are a monitoring signal rather than an official government assessment. As NRW officials reiterated, whatever the season, knowing what action to take if warnings are issued remains a sensible step to help prepare for severe weather.
