Deep depression in Bay of Bengal triggers weather alerts for Bangladesh coast

A deep depression currently brewing over the northwest Bay of Bengal is moving toward the coastlines of West Bengal and Odisha, prompting weather officials to issue localized cautionary signals across Bangladesh. While the system is expected to cross the Indian coastline by Monday evening, the Bangladesh Meteorological Department (BMD) anticipates that the impact on the country will remain relatively limited.
The BMD has issued a Local Cautionary Signal No. 3 for the country’s four maritime ports, while inland river ports have been advised to hoist Signal No. 1. Despite the proximity of the weather system, meteorologist Md. Hafizur Rahman stated that while the depression is unlikely to trigger severe weather, it is expected to increase rainfall across coastal districts and other regions beginning Monday.
Precipitation is forecast to continue periodically through Thursday as the system moves across the region. While some areas may experience heavy rainfall—defined by the department as between 44 and 88 millimeters within a 24-hour period—forecasters consider the likelihood of extreme, catastrophic rainfall to be low. Dhaka is also expected to receive rainfall during this period, though the intensity remains uncertain.
This transition in weather follows a period of significant atmospheric instability that began on September 5. Heavy downpours earlier this month triggered widespread waterlogging in Dhaka and Chattogram, while flooding affected at least nine districts, causing notable damage to agricultural crops.
As the current deep depression tracks away from the country, authorities are monitoring the situation closely. Rainfall is expected to intensify by Wednesday, with the wet conditions likely to persist until the end of the week.
