The Met Office has issued an amber weather warning – for extreme heat in eastern, southern and central parts of Scotland – which is in force until midnight on Wednesday. Ahead of soaring temperatures, which weather experts believe could pass the August 2003 record of 32.9C at Greycrook in the Scottish Borders, Holyrood minister Keith Brown urged people “to think about whether they need to travel and, if they do, make sure they’re properly equipped and plan their journey in advance”. On Monday, the mercury rose to 31.3C in Aboyne in Aberdeenshire and Leuchars in Fife, the Met Office said. Meanwhile, the Royal Botanic Garden in Edinburgh recorded 30.8C and temperatures peaked at 29.9C in Aviemore. Edinburgh is today predicted to reach 31C, while Glasgow will see the mercury rise to around 28C. But in Aboyne, thermometers could reach 32C, and in Coldstream, in the Scottish Borders, the mercury could soar to 34C.
