The Met Office has issued a yellow thunderstorm warning for southwest England and Wales today, with heavy rain, lightning, and hail expected across a significant portion of the region. The warning comes into effect at 10am this morning and is due to last until 9pm tonight, affecting areas including Devon, Cornwall, Somerset, Bristol, and much of South Wales.
Forecasters predict intense downpours in some areas, potentially leading to localised flooding and difficult driving conditions. The Met Office warns that up to 50mm of rain could fall in a short space of time, raising concerns for surface water flooding in urban areas and on roads. In addition, there is a risk of lightning strikes and hail, which could cause damage and disrupt services.
The expected weather conditions are likely to impact daily activities and travel. Public transport may experience delays or cancellations, while motorists are urged to exercise caution due to reduced visibility and hazardous road surfaces. There is also a slight chance of power cuts and other disruptions where lightning strikes occur. Wind speeds are generally light, around 5-10 mph, but could be stronger near thunderstorms.
Looking at regional specifics, temperatures across southwest England are expected to reach highs of 22-24°C before the storms arrive, feeling humid. In Wales, similar temperatures are forecast, with Cardiff potentially seeing around 23°C. Northern Ireland and Scotland are expected to remain largely clear of these specific thunderstorm warnings today, generally experiencing a mix of sunshine and some showers.
The Met Office advises residents to stay updated with the latest forecasts and take precautions to secure outdoor items during peak storm activity. Drivers should be vigilant for standing water and spray, and never attempt to drive through floodwaters.
