UK faces fourth heatwave with temperatures up to 35C

The UK is bracing for its fourth heatwave of the year, with temperatures forecast to reach 35C by Wednesday, triggering amber heat health alerts and an appeal from fire chiefs to avoid disposable barbecues amid tinder-dry conditions. July has been 3C above average, with southern England receiving just 1% of its usual rainfall. The heat is expected to be short-lived, cooling from Thursday.
