Dhaka: The Bangladesh Meteorological Department (BMD) today announced a forecast of heavy to very heavy rainfall in the northern and adjoining regions of the country starting this evening, raising concerns about potential temporary flooding in the northeast.
According to Bangladesh Sangbad Sangstha, low-lying areas of Sylhet and Sunamganj are at particular risk of short-term flooding due to the anticipated excessive rainfall and runoff from upstream regions. Meteorologist Dr. Muhammad Abul Kalam Mallik reported that deep convective clouds forming over the northern areas may lead to sustained rainfall over the next 96 hours. He further mentioned that parts of Sylhet and Mymensingh divisions could experience heavy showers, resulting in temporary waterlogging in city areas.
Mashiur Rahman, Managing Director of the Bangladesh Weather Observation Team, explained that a pre-monsoon rain band named “Jhumul” is approaching Bangladesh and may remain active until May 7. This system could bring widespread rain, thunde
rstorms, and Kalbaishakhi storms across much of the country, with the heaviest rainfall expected in the northeastern regions. He noted that upstream areas such as Meghalaya, Assam, and Cherrapunji may receive 500-700 mm of rainfall, increasing the risk of flash floods from hill runoff into Bangladesh. However, any flooding is expected to be short-lived as water levels may recede quickly.
Rainfall is projected to intensify from tonight and gradually spread across the country from April 28 or 29. Between April 29 and May 5, around 70-80 percent of the country may experience regular rain and thunderstorms, with only brief breaks. In dismissing rumors circulating on social media, Mashiur Rahman clarified that there is no possibility of temperatures rising to 45-57°C. Instead, the increased rainfall is expected to lower temperatures in the coming days.
