The Met Office has sounded the alarm with a rare red weather warning for parts of Wales and specific areas in England, as torrential rain threatens to unleash catastrophic flooding and transport chaos over the next two days.
Residents in south Wales - including Powys, Carmarthenshire and Neath Port Talbot - face a high risk of flooded homes and businesses, with forecasters predicting up to 100mm of rainfall in some areas. The West Midlands is also expected to bear the brunt of the deluge, with isolated spots potentially seeing even higher totals.
Travel conditions will become extremely hazardous, with major road closures and disruptions to public transport services likely. Communities may be cut off due to impassable roads, and power cuts affecting essential services cannot be ruled out.
The emergency services are urging residents to take immediate precautions, including avoiding non-essential travel and securing outdoor items. Those living in flood-prone areas should review their flood plans and move valuable items to higher ground.
While other parts of the UK face unsettled weather, the red warning applies only to these specific regions. Yellow and amber warnings remain in place for England's North West and Scotland, while Northern Ireland sees a mix of showers and drier spells.
The slow-moving low-pressure system driving the rain is expected to move away by the end of the 48-hour period, but residual flooding impacts could persist as river levels remain high. Authorities will continue to monitor the situation closely.
