This follows the hottest bank holiday and hottest May night on record. Forecasters predict temperatures could climb to 36C in parts of southern England and Wales, potentially breaking the record again. A yellow weather warning for "intense" thunderstorms, with lightning and hail, has been issued, alongside extended amber and yellow heat health alerts until Thursday. Four teenagers died in separate water-related incidents over the bank holiday weekend, prompting warnings from the Royal Life Saving Society about the dangers of cold water shock and advising people to "float to live" if in trouble. Rail operator LNER implemented speed restrictions on some routes due to the heat, causing delays, and altered services to use trains with better air conditioning. Despite the heatwave, England's water resources are currently in a good position due to an "exceptionally wet winter," with no areas in drought. The unusually hot weather is also affecting much of Western Europe, with parts of France experiencing temperatures 10°C above average for May.
