Following record high temperatures for the UK on Tuesday, a yellow storm warning is now in place for much of southern and western England and eastern Wales. Storm warnings have been in place since Wednesday, which have now been extended until Friday, reaching north-east Wales and Merseyside, as well as south-east England. Areas affected also include most of south and mid-west Wales, Gloucestershire, Wiltshire, Somerset, Devon, Hampshire and Sussex. A yellow warning is in effect from 10am. until 10 p.m. of Friday. The Met Office is warning that some areas will remain dry, but other areas could see “slow-moving showers and thunderstorms” from mid to late morning before dissipating in the evening. Where thunderstorms occur, 20-25mm of rain could fall in less than an hour, while one or two places could see 40-55mm in two or three hours. The Met Office said that where there are thunderstorms, people should expect spray and flash flooding which could lead to difficult driving conditions and some roads. There may also be train and bus delays and cancellations where there is flooding or lightning. And there’s also a “slight chance” of power outages.
