Met Office Issues Amber “Danger to Life” Warning as Heavy Rain Batters UK
South Wales and neighbouring regions face up to 120 mm of rain, with flooding and travel disruption likely through early week
The UK’s national weather service has issued an amber “danger to life” warning across much of south Wales as heavy rain lashes the region, raising major concerns about flooding, travel disruption and public safety.
The alert, which comes into force late Sunday night and remains in place through Monday night, forecasts 60–80 mm of rainfall — with some upland areas expecting as much as 100–120 mm — and warns of fast-flowing or deep floodwater, power interruptions and hazardous travel conditions.
Authorities are urging those in affected areas to brace for potential flooding, stay away from swollen rivers, and avoid driving through floodwater.
With rivers already elevated and soil saturated from prior rainfall, the likelihood of surface water flooding and river overflows is elevated.
The Met Office has also highlighted stark secondary hazards: widespread travel disruption due to flooded roads or rail cancellations, possible power cuts, and risk to life posed by deep or fast-moving floodwater.
Residents have been urged to stay updated via official channels and to register for flood warnings if not already enrolled.
Beyond Wales, additional yellow warnings are in place across parts of England, including the West Midlands, northwest and northeast England, Yorkshire, and the northeast — where heavy rain, icy patches, strong winds and localized flooding remain possible through the early hours of Tuesday.
Wet conditions and a temperature drop could further increase hazards, particularly on untreated roads and rural routes.
The severe spell arrives as the start of the Advent season coincides with a developing low-pressure system pushing in from the Atlantic.
While rain may ease later in the week in some regions, forecasters caution that the risk of flash flooding — particularly across western and upland areas — will persist unless there is a sustained dry spell.
Communities, transport networks and essential services have been put on alert for potential disruption.
Residents and businesses across threatened areas are being advised to act with caution, secure property where possible, and adjust travel plans ahead of what could be a prolonged and challenging start to the week for many parts of the UK.
