Half a month's rain will hammer parts of the UK within 24 hours from Friday, with the Met Office warning that up to 50mm could fall in some areas. The deluge threatens localised flooding and major travel disruption across England and Wales, representing nearly two-thirds of June's typical 75mm monthly rainfall total.
Yellow weather warnings cover large swathes of England and Wales, signalling moderate risk of impact. Central and southern England face the worst conditions, including the Midlands, East Anglia, and parts of the South West, alongside much of Wales. Scotland and Northern Ireland will largely escape the heaviest downpours, though southern and eastern Scotland may still see persistent rain.
A slow-moving Atlantic low pressure system is driving the extreme weather, drawing moisture across the UK. The heaviest rain will strike Friday afternoon through Saturday morning, accompanied by winds gusting 30-40 mph along exposed coasts. Despite the soaking, temperatures will remain mild at 12-16°C across affected regions.
Residents should check local flood warnings and clear drains where safe, the Met Office advises. Motorists face challenging conditions with standing water and poor visibility, whilst pedestrians and cyclists must take extra care. The Environment Agency and Natural Resources Wales stand ready to monitor river levels and respond to flooding incidents.
The intense rainfall caps a changeable start to summer across Britain, underscoring the unpredictable nature of the country's weather patterns. Forecasters continue monitoring conditions for potential weekend developments as communities brace for the immediate 24-hour downpour.
