People in Wales are being advised to prepare for "the unthinkable" as flood response teams warn of an increased risk over the autumn. Natural Resources Wales (NRW) expressed concern over long-range forecasts suggesting a greater likelihood of wetter and windier weather than is typical for the coming months.
One in seven properties in Wales is classified as being at risk of flooding. However, NRW noted that only 27% of those eligible to receive flood warnings to their phone or email are currently signed up. The organisation has urged people "not to become complacent" following a summer of drought and wildfires, stating that conditions could change rapidly.
Wales has experienced several significant floods in recent years, often following powerful storms. The threat stems from rivers, the sea, and surface water flooding, which is considered an increasing danger. Jeremy Parr of NRW highlighted that the country's geography, with its vast coastline and "fast-responding" rivers, makes it particularly vulnerable.
More than 274,500 homes and businesses are currently at risk of flooding, a figure projected to rise significantly by the end of the century. Residents in flood-hit areas, such as Monmouth, have shared concerns and begun preparations, recalling "harrowing" scenes from major flooding in November 2025.
Sarah Davies from the Met Office confirmed that long-range forecasts for October, November, and December suggest "a greater chance of weather-related disruption." She advised that understanding flood risk and knowing what actions to take if warnings are issued are sensible steps for preparation.
