A low-pressure system developed over the Bay of Bengal on Tuesday, according to the Bangladesh Meteorological Department. This system is expected to intensify rainfall across the country, particularly over the next three days.

Heavy to very heavy rainfall is likely in parts of northern, northeastern, and southeastern Bangladesh. The Bangladesh Water Development Board has issued warnings of possible flash floods and short-term inundation in these regions.

Due to intense rain, landslides are feared in hilly areas of Chattogram, Rangamati, Khagrachari, Bandarban, and Cox's Bazar. In anticipation of strong winds, the Meteorological Department has advised local ports—including Chattogram, Mongla, Payra, and Cox's Bazar—to hoist local cautionary signal number 3.
