The Met Office has issued a critical warning: millions in parts of UK are bracing themselves for potentially devastating thunderstorms that could bring torrential rain and lightning within hours. Heavy downpours, with some areas expected to see up to 30mm of rainfall in just a few hours, pose a significant risk of power disruptions, outdoor activities being cancelled, and surface water flooding in low-lying areas.
Forecasters anticipate that the storms could bring between 15-20mm of rain in a short space of time, with frequent lightning strikes expected to accompany the heavy downpours. Gusty winds may also be present but are not considered the primary concern. Regions likely to be affected include parts of Greater London, the South East, East of England, and the Midlands in England, as well as eastern areas of Wales.
Residents in these areas are advised to prepare for potential travel delays on roads and public transport, as well as surface water flooding in low-lying areas. While the warning is localised, thunderstorms can be unpredictable, making it essential to stay informed through official channels. Checking local weather updates and travel information before making journeys is also crucial.
The Met Office stresses that safety advice includes staying indoors during the storms, avoiding contact with electrical equipment, and not sheltering under trees or near exposed metal structures. Motorists are urged to drive with caution, reducing speed and being mindful of spray and sudden flooding. This warning comes after a period of mixed weather across the UK, with generally mild temperatures but an increasing risk of convective activity.
The Met Office continually monitors weather patterns and updates warnings as necessary. It advises the public to stay informed through official channels and take the necessary precautions to ensure their safety during the storms.
