Britain braces for severe thunderstorms and floods after fifth summer heatwave

The United Kingdom is facing a dramatic weather shift as severe thunderstorms and flash floods are forecast, following the country's fifth heatwave of the summer. The Met Office has issued yellow warnings for heavy rain, hail, and strong winds across large parts of Britain, signaling a turbulent end to the recent period of extreme heat and drought.

These warnings are in place for Northern Ireland, northeast Scotland, and significant portions of northern England, including major cities like Manchester, Liverpool, and Newcastle. Forecasters anticipate intense rainfall that could lead to flooding of homes and businesses, disrupt travel, and cause power outages. The sudden change in weather comes after a period where temperatures soared, with the Kew Gardens in London recording a high of 38.1 degrees Celsius last Thursday, marking the hottest day of the year.

However, the incoming rain is not expected to immediately alleviate the drought conditions gripping the country. As of Wednesday morning, some areas had recorded up to 23 millimeters of rain, but this is insufficient to counteract the prolonged dry spell. The Environment Agency and Natural Resources Wales have urged the governments of England and Wales to declare a drought emergency for the River Severn, Britain's longest river, due to the severe impact on ecosystems and surrounding agriculture.

Authorities are particularly concerned about the rapid transition from drought to heavy rainfall. The parched ground, baked hard by weeks of intense heat, has a reduced capacity to absorb large volumes of water quickly. This increases the risk of surface flooding, as much of Wales and nearly three-quarters of England remain under drought conditions, affecting approximately 71.3% of the country.
