The Met Office has sounded the alarm with an urgent warning of thunderstorms sweeping across 54 areas in England, Scotland, Wales, and Northern Ireland today, threatening to bring frequent lightning, heavy downpours, and localised flooding. The yellow weather warning came into effect at 10:00 BST and will remain in place until 19:00 BST.
Forecasters are predicting that some areas could see as much as 20-30mm of rain fall within an hour, with a small chance of up to 50mm in just two to three hours. This intense rainfall poses significant risks to drivers, who will face difficult conditions due to surface water and reduced visibility. There's also a slight possibility of power cuts and disruptions to public transport services.
The warning covers a vast swathe of the country, with particularly high-risk areas including the North West, Yorkshire and the Humber, East Midlands, West Midlands, and parts of the South West in England. Scotland will see warnings for Strathclyde, Central, Tayside & Fife, and the South West, while Wales is set to be hit by alerts in Powys, Carmarthenshire, and Monmouthshire. All counties in Northern Ireland have been issued with a blanket warning.
Temperatures will remain mild to warm in many affected areas, potentially contributing to the unstable atmosphere that fuels thunderstorms. Winds are expected to be light, around 5-10 mph, but gusts could reach higher speeds during intense downpours, particularly near storm cells.
The Met Office is urging residents to take precautions and stay safe. Affected communities should consider unplugging non-essential appliances to protect against power surges from lightning strikes. It's also advised to avoid open spaces and water during a thunderstorm, and keep pets indoors where they feel secure. Drivers must be vigilant, allowing extra time for journeys and being prepared for sudden changes in weather conditions.
