Weather forecasters expect temperatures to reach around 32C across southern England on Tuesday, rising to 33C on Wednesday, 34C on Thursday and as high as 35C in isolated areas by Friday and Saturday.‌M&S said it is investing in equipment capable of coping with temperatures of up to 45C after food halls and stores struggled during June's extreme heat.‌Speaking at the M&S annual general meeting in London, chief executive Stuart Machin said some refrigeration units failed during the heatwave."There’s no doubt we were struggling in those nine days of extreme heat," he told shareholders. "Now we’re investing in equipment in our stores to deal with temperatures of 45C. We’re reviewing all our refrigeration as well."Food stores and supermarkets across the country experienced refrigeration problems during the June heatwave, when temperatures climbed to 37.7C – the highest June temperature ever recorded in the UK, surpassing the previous record set in 1976.‌The Met Office previously warned there is a 50:50 chance the UK could experience temperatures of 40C again within the next 12 years as climate change increases the risk of extreme heat. It has also said temperatures of 45C or higher may now be possible in the UK's current climate.The forecaster published a "plausible" future scenario showing a June heatwave in 2056 with temperatures peaking at 45C in England, after the UK exceeded 40C for the first time on record in 2022.Amber heat health alerts are in force this week for the East Midlands, West Midlands, East of England, London, the South East and the South West, from 9am tomorrow until 9pm on July 12.‌Yellow alerts covering the same period have also been issued for the North East, North West and Yorkshire and the Humber.Met Office Deputy Chief Forecaster Steven Keates said parts of the UK were entering the third heatwave of the year."However, unlike the May and June heatwaves, we are not expecting this heatwave to be record-breaking. Temperatures this week are not expected to reach the highs we witnessed last month, though parts of southern England in particular are likely to see several days in the low 30s Celsius, and a few places could reach 34-35C later this week," he said.Article continues below"Night-time temperatures again will not be as high as what we experienced in June, though some larger urban areas are likely to remain in the high teens Celsius overnight, especially later in the week, and there is a chance that a tropical night (where temperatures do not fall below 20C) may be recorded in a few places."Choose Daily Mirror as a 'Preferred Source' on Google News for quick access to the news you value.‌Met OfficeHeatwaveMarks & Spencer
