The United Kingdom is facing a severely wet start to the week, with substantial rainfall triggering multiple weather warnings and dozens of flood alerts across England and Wales. Forecasters warn that parts of Wales could see nearly a month's worth of rain in a single day, significantly increasing the risk of flooding and landslides.
Amber Warning Highlights 'Danger to Life' Risk
An amber rain warning, indicating a potential danger to life, is active for much of South Wales until midnight on Monday 1 December 2025. The Met Office states that fast-flowing or deep floodwater is possible, which poses a serious threat. The warning area could see up to 120mm of rain on the highest ground, with 20-40mm expected widely and up to 80mm in hilly regions.
Senior Met Office meteorologist Marco Petagna emphasised the severity, noting that the impact will be heightened because the ground is already saturated from above-average rainfall this November. Wales has already recorded around 240mm of rain this month, well above its November average of 162mm.
Widespread Disruption and Further Alerts
In addition to the amber alert, yellow rain warnings cover parts of south-west and north-west England, as well as central and northern Wales, until 3am on Tuesday. A separate yellow warning for south-west Scotland expired at 9pm on Monday.
The Environment Agency has issued five flood warnings where flooding is expected, alongside 44 flood alerts for England. Natural Resources Wales has listed 38 flood alerts, advising residents to be prepared. Officials warn that homes and businesses could be flooded, with possible transport cancellations, power cuts, and communities becoming cut off by flooded roads.
Longer-Term Outlook and Historical Context
The British Geological Survey has indicated that the volume of rain forecast has previously triggered landslides in Wales. The Met Office has stated that Monday could be a significant event for many and has chosen not to issue warnings beyond this period to avoid distraction from the immediate danger.
Looking ahead, the weather is expected to become brighter and more showery from Tuesday onwards, with less impactful conditions. For now, residents in affected areas are urged to stay updated on official advice and avoid unnecessary travel through flood-prone regions.
