The Met Office has issued a yellow thunderstorm warning for South Wales, with forecasters predicting heavy rain, lightning, and gusty winds set to cause significant disruption across the region. A broad swathe of areas will be affected by up to 30mm of rainfall per hour in some spots, which could lead to localised flooding, especially in urban centres and low-lying ground where drainage systems may struggle.
The warning highlights the potential for thunderstorms to cause a range of hazards, including power cuts due to lightning strikes, damage from strong winds, and surface water flooding that can make roads impassable. In addition, driving conditions will be hazardous, with reduced visibility, standing water, and debris on roads creating difficult journeys.
For those living in South Wales, the warning period is expected to bring sustained thunderstorms, and residents are urged to prepare for disruptions to power and transport services. The Met Office advises drivers to exercise extreme caution, consider delaying non-essential travel, and allow extra time for necessary journeys.
The affected areas primarily encompass parts of South Wales, including major population centres and surrounding rural regions. While specific timings may vary, the warning period indicates a heightened risk of thunderstorms throughout the region.
