Heavy Rainfall Expected in India, Bangladesh, Myanmar, and Surrounding Areas

Over the next three days, influenced by a monsoon trough and a tropical disturbance (Figure 1), heavy to torrential rain is expected across northern and central India, Nepal, Bhutan, Bangladesh, Myanmar, northern Thailand, and northern Laos. Isolated areas may experience intense downpours or extraordinarily heavy rainfall, accompanied by severe convective weather such as short-term intense precipitation and thunderstorm gales. Most regions can expect accumulated rainfall of 100-200 mm, with localized areas in northern India and Bangladesh exceeding 250 mm (Figure 2).
