Met Office issues thunderstorm and flood warnings across UK after record dry summer

· Environment GBR

The Met Office has issued yellow weather warnings for thunderstorms and flooding across large parts of the UK on Wednesday and Thursday, with up to 50mm of rain possible in some areas and more than 75mm over east-facing higher ground.

The warnings cover parts of east Wales, the Midlands, northern England, East Anglia, and southern England including London, where a band of heavy showers and thunderstorms is expected to hit the capital on Wednesday morning. Rainfall rates of 20-30mm in less than an hour are possible, with hail of around 1-2cm also forecast. The storms are expected to drift northwards from France.

The downpours follow an exceptionally dry period. July 2026 was the driest month since records began in 1836 in England and Wales, and 70 per cent of England and Wales is currently in drought. London has experienced one of its driest summers on record, with hosepipe bans declared and wildfires breaking out amid the conditions.
