UK schools plan closures as red heat alerts loom

The United Kingdom is preparing for potentially life-threatening temperatures as a red extreme heat warning is set to take effect across parts of England and Wales from Wednesday morning to Thursday evening. Hundreds of schools have announced at least partial closures, and major train operators are advising passengers to avoid travel unless absolutely necessary.

This heat is going to be quite intense and can have very serious life threatening effects even in people who are completely fit.

Temperatures climbed on Tuesday, with Wisley in Surrey recording a high of 34.6C. Northern Ireland and Scotland experienced their hottest days of the year, reaching 28.1C and 29C respectively, while Wales hit 32.2C. The heatwave is expected to intensify, with forecasts predicting highs of around 37C to 38C in southern England on Wednesday, and potentially up to 39C in some areas. High humidity levels will exacerbate the conditions, making 35C feel like 41C.

The Met Office's red warning signifies an exceptional spell of hot and humid weather, posing a risk of serious illness or danger to life. The agency also anticipates potential disruptions to essential services, including power and water, due to the strain on heat-sensitive systems. An increase in visitors to coastal areas and rivers is also expected, raising concerns about water safety.

signals a very widespread threat

Professor Robin May, chief scientific officer at the UK Health Security Agency (UKHSA), described the red heat health alert, issued for the second time since July 2022, as signaling a "very widespread threat." He emphasized that the warning applies not only to vulnerable groups like the elderly and young but also to otherwise healthy individuals, urging everyone to take extreme precautions against the intense heat's potentially life-threatening effects.

Often we are warning about the vulnerable, the elderly, the young, but in this case we're also warning otherwise healthy people in their prime of life to take very cautious steps.
