UK Officials Urge Public to 'Prepare for the Unthinkable' Amid Flood Warnings

Officials in Wales are urging residents to prepare for potential flooding this autumn, citing concerns over changing winter weather patterns and the potential impact of climate change. The warning comes after a severe flood event in Monmouth in November 2025, which residents described as "harrowing" and "dreadful."

Malcolm Butcher, 82, who has lived in Monmouth his entire life, recounted the "unbelievable" and "raging" waters that hit the town in the early morning hours. He noted that if the flood had occurred during the day, "people would have died." Eighteen cars on his street were lost, and houses behind his were flooded. "It is a worry, we have three rivers running into Monmouth... and the winters are changing," he said.

Residents are taking steps to prepare, with suggestions including moving valuables to upper floors and keeping sandbags readily available. "It's not back to normal yet but we're getting there," said Imogen Elliot, 82, who described the Waitrose supermarket being inundated with four feet of water.

Jeremy Parr of Natural Resources Wales (NRW) stated that more frequent and intense weather extremes are expected due to climate change. He also noted that the current El Niño event over the Pacific Ocean, described as the "strongest in living memory," is contributing to global temperature increases and raising the risk of extreme weather. While this doesn't guarantee severe weather in the UK, it is "part of the picture" causing concern for the upcoming months.

"We do invest in flood defences... but you can't stop all of the flooding all of the time," Parr explained. "So that means that people need to think the unthinkable really - or the unpleasant - and [consider] if it were to flood around where I live, what would I do?" He highlighted that many who have experienced devastating floods previously believed it would "never happen to them."

NRW advises the public to check their flood risk online by postcode, sign up for flood warnings, and access advice on how to respond if flooding is forecast. The organization's flood warning service is available to over 181,000 properties in Wales, but only about 48,000 (27%) are currently signed up to receive alerts. Parr suggested that misinformation about insurance premiums might be deterring people from signing up.
