The country is bracing itself for the worst as an unprecedented red extreme heat warning has been issued by the Met Office for parts of England. With temperatures potentially reaching a record-breaking 40 degrees Celsius, the nation's infrastructure, communities, and individuals are at risk.
This marks the first time such a warning has been issued for heat in the UK, reflecting the severity and potential impact of the anticipated weather. The previous highest recorded temperature was 38.7C, set in Cambridge in 2019. Forecasters now indicate a strong possibility that this record will be surpassed, with a 50% chance of temperatures reaching 40C somewhere in the UK, and an 80% chance of a new national record.
The red warning extends across central, eastern, and south-eastern England, including major urban centres and rural areas. While the most extreme temperatures are expected here, other parts of the country will also experience very high temperatures. In Scotland, amber warnings for extreme heat have been issued for parts of the central belt and southern regions, with temperatures potentially reaching the high 20s. Wales is under an amber warning, with forecasts of temperatures in the mid-30s, particularly in eastern areas. Northern Ireland can expect low to mid-20s, with a yellow warning for high temperatures.
The Met Office advises taking immediate action to protect yourself from the heat. Stay indoors during the hottest parts (11 am to 4 pm), drink plenty of water, wear loose, light-coloured clothing, and check on vulnerable friends, family, and neighbours. The extreme heat poses a significant risk of heatstroke and heat exhaustion, particularly for the very young, elderly, and those with underlying health conditions. Infrastructure is also at risk, with potential for road surfaces to melt, rail lines to buckle, and power networks to be strained.
Emergency services are preparing for an increased demand, and the NHS has issued guidance to help people cope with the heat. Employers are urged to consider their staff's welfare, particularly those working outdoors or in environments without air conditioning. Travel disruption is highly likely, with warnings issued for public transport and advice against non-essential journeys during peak heat.
The prolonged period of extreme heat is attributed to a combination of factors, including a plume of hot air from southern Europe and high pressure systems over the UK. Scientists highlight the increasing frequency and intensity of such heatwaves as a consequence of climate change, making this event a stark reminder of the broader environmental challenges facing the nation.
