The Met Office has issued an extension to its amber extreme heat warning, covering parts of the UK, even as temperatures are predicted to cool to around 25C. This decision comes after a prolonged period of high temperatures and ahead of potential thunderstorms across some regions. The warning highlights the continued health risks associated with the heat, particularly for vulnerable groups.
For England, the amber warning primarily affects central and southern areas, where temperatures have consistently been elevated. While a slight decrease is expected, conditions will remain warm and humid. The risk of isolated thunderstorms is also present across various parts of England, which could bring heavy downpours and lightning, potentially disrupting travel and outdoor activities. In contrast, northern England and Scotland are generally expected to experience slightly cooler and more settled conditions, although isolated showers cannot be ruled out.
Wales is also included within the scope of the extended warning for certain eastern and southern areas, where the heat will persist, albeit at a slightly lower intensity than previous days. Thunderstorm activity is also a possibility here, particularly in the afternoon and evening. Northern Ireland is forecast to see a mix of sunshine and some showers, with temperatures generally milder compared to the south of Great Britain, typically ranging from 18C to 22C.
The Met Office advises the public to remain vigilant, even with the slight dip in temperatures. The extended warning signifies that the cumulative effects of the heat, combined with potential humidity and the risk of storms, still pose a threat. Practical safety advice includes staying hydrated, seeking shade during the hottest parts of the day, and checking on elderly or vulnerable neighbours and relatives. Wind speeds are generally expected to be light to moderate, typically between 5-15 mph, but could gust higher during thunderstorms.
The presence of thunderstorms could bring localised issues such as flash flooding and power outages, further complicating the weather picture. While the peak intensity of the extreme heat may be easing, the combination of warm temperatures and volatile weather fronts necessitates continued caution from the public and emergency services.
