The UK is bracing for a deluge of heavy rain and thunderstorms, with the Met Office issuing multiple yellow weather warnings affecting primarily southern England, Wales, and the South West. Heavy downpours are expected from Wednesday night through Friday, with up to 100mm of rain forecasted in some areas, causing concerns about flooding, travel disruptions, and power outages. The weather warnings cover a wide range, including parts of London, which may experience sporadic sunny spells amidst the rain. Meanwhile, Bangladesh is also expecting heavy rainfall due to a low-pressure system over the Bay of Bengal, affecting regions such as Rangpur, Mymensingh, and Sylhet. Similarly, parts of Maharashtra, Gujarat, and Kerala in India are forecasted to see heavy rain, with heightened alerts and advisories issued by the India Meteorological Department (IMD). Overall, the weather conditions are expected to be challenging in these regions over the coming days.
