UK Weather Alert: A Month’s Worth of Rain in 24 Hours as Met Office Issues Warnings for Flooding and Heavy Snow

Published on November 30, 2025

The Met Office has issued a series of severe weather warnings across Wales and England as a winter storm moves in. The weather warnings include significant heavy rain, snow, and the potential for widespread flooding, particularly in South Wales, which could lead to dangerous conditions and severe travel disruptions. UK travelers are being urged to stay alert, as over 120mm of rain could fall in some areas within 24 hours—equivalent to a month’s worth of rain.

With the storm affecting multiple regions, including Merseyside and the South West, residents and travelers alike must plan for potentially hazardous conditions over the coming days. The weather warnings are not limited to just rain; snow has already begun affecting parts of Britain, and the situation is expected to worsen, with disruptions to transportation, business activities, and tourist visits likely.

Widespread Rain and Risk of Flooding in South Wales and Beyond

The Met Office’s amber warning for heavy rain will be in effect across South Wales starting from midnight and lasting throughout Monday, with the highest rainfall expected to accumulate on the higher ground in the region. It is predicted that up to 120mm of rain could fall, with 60-80mm likely in many hills and 20-40mm at lower levels. This rainfall is expected to exacerbate the risk of flooding in already saturated areas, particularly in river valleys and low-lying parts of Wales.

Travel disruption is a key concern as water levels rise, potentially causing road closures and delays in train services. Merseyside, Manchester, and other nearby regions in the North West of England will also experience heavy rain, with the Met Office issuing a yellow warning for these areas. Travelers in these regions should anticipate significant traffic delays and potential cancellations of flights or train services. The weather’s impact on business operations could also be severe, particularly for logistics companies and retail businesses.

Risk to Life and Property: Flood Warnings and Emergency Response

The situation is serious, with flood warnings issued across multiple parts of the UK. Natural Resources Wales and the Environment Agency have been actively monitoring river levels and warning residents of the potential for fast-flowing or deep floodwater. Richard Preece, the Duty Tactical Manager for Natural Resources Wales, emphasized that the heavy rainfall predicted could lead to dangerous conditions, especially with already swollen rivers. Authorities are urging residents in flood-prone areas to remain vigilant and to take immediate precautions.

Tourists planning to visit attractions in the affected regions, particularly those near rivers, should avoid areas where flooding is likely. Even areas that are not directly affected by flooding could still experience difficult travel conditions due to poor road conditions and public transport disruptions. Tourists are advised to check weather updates regularly and plan for delays, especially if heading to areas like Cardiff or Newport, where the rain may cause major issues.

Travel and Business Impact: A Winter of Disruptions

Travelers should expect significant disruptions, especially for those planning to travel via airports or train stations in affected areas. London Heathrow and Cardiff Airport are both likely to experience delays due to the severe weather. Additionally, roads across South Wales and the North West of England may become treacherous, with slippery conditions and flooding creating serious risks for drivers.

For business travelers, these weather conditions could lead to delayed meetings, cancellations, or postponements of corporate events in the affected areas. Retail businesses may face difficulty in maintaining stock delivery schedules, and public services could be delayed due to the disruption caused by the rain and snow.

For tourists, while many indoor attractions are open, it is important to check the status of outdoor attractions, including Christmas markets and outdoor events, as these may be either closed or reduced in capacity due to the weather. Those with plans to visit popular outdoor spots like Snowdonia or the Cotswolds should reconsider or make flexible plans in case of adverse weather conditions.

How to Stay Safe and Minimize Disruption

1. Check Local Weather Alerts: Travelers should keep up-to-date with Met Office warnings and local weather stations for the latest on rain, snow, and flooding in the areas they plan to visit.
2. Allow Extra Travel Time: With expected traffic delays and possible public transport disruptions, travelers should allow for extra time when commuting to work, meetings, or tourist destinations.
3. Prepare for Flooding: Travelers heading to areas near rivers or coastal regions should be mindful of flooding risks. Check the Environment Agency website for the latest flood alerts.
4. Review Accommodation and Activities: Make sure that your hotel or accommodation is prepared for the weather conditions and check for any changes to outdoor activities due to the weather.
5. Use Weather Apps: Stay informed on weather changes with apps like BBC Weather or Met Office, which can help provide real-time updates on weather conditions, particularly for snow and rain.
