Summary
- Government issues red alert for heavy rain and flooding
- Up to 70mm of rain expected in parts of UK
- Residents urged to take action and protect themselves

As of August 29th, 2025, the UK government has issued a critical red alert urging communities to take immediate action in response to severe flooding triggered by heavy overnight rain. The Met Office had previously put a yellow weather warning in place, forecasting up to 70mm of rain in parts of Kent, Essex, Sussex, Surrey, London, and South Wales.
The red flood alert names six specific areas as being most at risk, including the River Pol and Langreek Stream in Polperro, Cornwall. Residents in these locations have been strongly advised to protect themselves, their loved ones, and pets by moving to higher ground or upper floors, securing valuables, and implementing flood protection measures.
Authorities warn that the floodwaters are expected to be deep and fast-flowing, posing a serious threat to homes, businesses, and infrastructure. Brits are advised to turn off utilities if safe to do so and follow all instructions from emergency services. The situation is considered an immediate flood emergency, with the potential for significant disruption to roads, railways, and coastal areas.
Amber alerts are also in place for other affected regions, and officials caution that river levels will peak in the morning, requiring ongoing vigilance from those living in the impacted zones.
