The UK is set for a sweltering 40C blast this weekend, as a red heat alert grips the nation. Hundreds of schools have already shut their doors, with many more likely to follow suit due to the 'exceptional' heat forecast by the Met Office. The health implications are also serious, with the NHS issuing stark warnings about staying cool and hydrated.
The Met Office's red warning, which is its highest level of alert, was triggered on Thursday and is expected to remain in place until at least Saturday, although the exact duration remains uncertain. Rail services have already been affected, with some trains cancelled or delayed due to the heat. The extreme temperatures are being driven by a high-pressure system sweeping in from Europe.
The NHS has sounded a particular alarm for vulnerable groups, including older people and young children. They urge everyone to take precautions against heat-related illnesses, seeking medical help if symptoms persist. Meanwhile, the Met Office warns of widespread disruptions to power supplies and transport networks as the heat takes hold.
