A yellow thunderstorm warning has been issued by the Met Office for large swathes of the UK today, following a night of significant storms that brought heavy rain and lightning across several regions. The warning highlights the potential for further downpours, strong winds, and the risk of localised flooding and disruption to travel and power supplies.
Overnight, areas including parts of England, Scotland, and Northern Ireland experienced intense thunderstorms. Eyewitness reports described vivid lightning displays and torrential rain, particularly in urban areas. While specific rainfall totals for the overnight period are still being assessed, the ground is already saturated in many places, increasing the risk of surface water flooding with any further heavy precipitation.
The current yellow warning, active for much of Wednesday, covers central and southern England, parts of Wales, and Northern Ireland. Forecasters predict that these areas could see rainfall accumulations of 20-30mm in an hour, with some isolated spots potentially receiving up to 50mm over a few hours. Gusts of wind reaching 30-40 mph are also possible during intense storm cells. Temperatures are expected to remain mild, generally ranging from 15-18°C in affected areas.
For England, regions most likely to be impacted include the Midlands, East Anglia, and parts of the South East and South West. In Wales, central and eastern areas are under the warning. Northern Ireland is also expected to see further thunderstorm activity. Scotland, particularly its southern regions, may also experience some residual storm activity, although the primary focus of the warning is further south. The Met Office advises residents in these areas to be prepared for potential power cuts, delays to public transport, and difficult driving conditions due to standing water and reduced visibility.
The public is reminded to take precautions during thunderstorms. This includes unplugging non-essential appliances, avoiding travel where possible during peak storm activity, and ensuring that drains and gutters are clear to help manage rainwater. Those planning outdoor activities should check the latest weather forecasts and be aware of the sudden onset of severe conditions.
