A red extreme heat warning has been extended across swathes of Sussex and Surrey, as a historic three-day heatwave threatens to bring temperatures in some areas of England above 40°C. This marks the first time such a warning has been issued for the UK, underscoring the unprecedented nature of the impending heatwave.
The red warning now covers parts of central, eastern, and south-eastern England, including much of southern counties mentioned earlier, with an amber extreme heat warning remaining in effect for most of England and Wales. Temperatures are expected to reach into the mid-to-high 30s Celsius across these areas, while Scotland and Northern Ireland will experience very warm conditions, albeit not as severe.
The Met Office has forecast Monday and Tuesday as the peak days of the heatwave, with overnight temperatures set to remain unusually high, failing to drop below 20°C in many urban areas. This prolonged exposure will exacerbate health risks, particularly for vulnerable individuals, who are urged to stay indoors during the hottest parts of the day (11 am to 3 pm).
Health authorities recommend staying hydrated by drinking plenty of water, wearing loose, light-coloured clothing and checking on elderly relatives and neighbours. Pet owners should keep their animals safe from the heat, while public transport services may face disruption due to speed restrictions on railways and potential issues with melting tarmac.
The heatwave will put a significant strain on infrastructure, including road and rail networks, and there is an increased risk of wildfires in rural areas. Authorities are urging people to remain vigilant and follow official guidance to mitigate the risks associated with this exceptional weather event.
This extreme heat serves as a stark reminder of the need for long-term adaptation strategies to address increasing frequency and intensity of extreme weather phenomena in the UK. The Met Office will continue to monitor the situation closely and update warnings as necessary, advising people to stay informed and take precautions to protect themselves and their property.
