The Met Office has issued a stark warning as heavy rain and thunderstorms are forecast to lash parts of the UK, including Cardiff and London, over the coming days. Residents in affected areas should brace for potential travel chaos and localised flooding.
Severe Weather on the Horizon
Forecasters predict that an area of low pressure moving in from the east will bring persistent and, at times, torrential rainfall across southeast England and parts of Wales. The worst of the weather is expected to hit Cardiff and London, where up to 40mm of rain could fall in just a few hours.
Key Impacts to Expect
- Flash flooding in low-lying areas
- Possible disruption to road and rail networks
- Reduced visibility for drivers
- Potential power cuts in some locations
Met Office Advice
A Met Office spokesperson stated: "We're urging people to stay updated with the latest forecasts and warnings. If you're travelling, allow extra time for your journey and be prepared for difficult driving conditions."
The weather system is expected to move northeastwards throughout the day, gradually easing by evening. However, forecasters warn that similar conditions could return later in the week as unsettled weather patterns dominate.
Regional Breakdown
Cardiff: Heavy showers developing through the morning, with thunder possible by afternoon.
London: Persistent rain moving in from the southeast, potentially turning thundery in places.
