The Met Office has issued a yellow weather warning for thunderstorms across parts of England and Wales, cautioning residents and travellers of potential disruptions. The warning, which came into effect on Wednesday evening, remains in place until 4am on Thursday. It covers areas including the East Midlands, West Midlands, North West, South West, South East, and Wales.
Impacts of the Warning
Forecasters have warned of heavy rain, hail, and spray that could significantly affect drivers, leading to hazardous road conditions. There is also a likelihood of damage to buildings from lightning strikes, as well as delays to public transport services. The Met Office has indicated that localised flooding is possible, along with short-term power cuts in affected regions.
Record-Breaking Heat Precedes Storms
The thunderstorm warning follows Tuesday, which was recorded as the hottest day in May on record for both England and Wales. According to the Met Office, Kew Gardens provisionally reached 35.1°C, while Cardiff Bute Park saw temperatures hit 32.9°C. The extreme heat has prompted health alerts and concerns for vulnerable groups.
Health Alerts Extended
Health officials have confirmed that heat health alerts will be extended for an additional 24 hours. The UK Health Security Agency stated that amber alerts remain in place for the South West, South East, London, East and West Midlands, and the East of England until 5pm on Thursday. Yellow heat-health alerts are also active for the North West and North East. Duncan Burton, chief nursing officer for England, urged caution, particularly for new parents, as NHS advice page visits for baby sun safety surged by 3,500% over the bank holiday weekend.
Dangers of Open Water
Amid the warm weather, fresh warnings have been issued about the dangers of open water following several tragic incidents. Multiple teenagers have died after getting into difficulty in recent days. In Cheshire, the body of a 17-year-old boy was recovered from Pickmere Lake. A 15-year-old boy, Declan Sawyer, died at Swanholme Lakes in Lincoln, and a 13-year-old boy, named locally as Reco Puttock, died at Leadbeater Dam in West Yorkshire. A teenage girl's body was recovered from Kingsbury Water Park in Warwickshire, and a man in his sixties died of cardiac arrest after entering the sea at Tregirls Beach in Padstow to help family members.
Police and RNLI Warnings
Chief Inspector Jamie Lewis of Cheshire Police emphasised the hidden dangers of open water, including currents and submerged objects. The RNLI also warned of the “very real risk” of cold water shock, noting that while air temperatures have been high, water temperatures remain low. They urged the public to avoid swimming in open water during the heatwave.
Looking Ahead
Temperatures are expected to cool slightly across the UK in the coming days, but health alerts remain in place. The public is advised to stay vigilant, check on vulnerable individuals, and avoid open water swimming to prevent further tragedies.
