The Met office has warned that Dhaka may experience some flooding, as prolonged heavy rains might cause the Buriganga, Balu, Shitalakhya and Turag rivers to break their banks.
The Bangladesh Meteorological Department said rain that began on Tuesday will continue until the first week of September and may cause flooding in Dhaka, as the surrounding low lying areas of Manikganj, Munshiganj and Narayanganj have already been inundated with floodwater.
According to the Flood Forecasting and Warning Centre (FFWC), the place from where the floods are most likely to enter Dhaka is through the east, should water level of the Balu River increase by 20cm, crossing the danger level.
Experts, however, say it is highly unlikely that Dhaka might actually be flooded unless heavy rains cause the embankments to break.

“Because of the embankments protecting Dhaka city, the chances of Dhaka being flooded is pretty low,” said Executive Engineer of FFWC Md Sazzad Hossain.
According to Bangladesh Meteorological Department, light to moderate rain/thunder showers accompanied by temporary gusty wind is likely to occur at many places over Dhaka, Mymensingh, Rangpur, Rajshahi, Khulna, Barisal, Chittagong and Sylhet divisions this week.
“Light to moderate rainfall is likely to occur in Dhaka in the next three days while heavy rains are expected from next week,” Meteorologist Arif Hossain told the Dhaka Tribune.

Experts said the floods in the northern districts of Dinajpur, Bogra, Nilphamari and Kurigram were caused by the breaking of embankments.
Executive Engineer of FFWC Md Sazzad Hossain also said: “The embankments on the western side of Dhaka is strong enough to withhold the floods if they happen but since the water levels of the Padma and Meghna have already decreased, the chances of flooding in Dhaka is low. If anything, there is a chance of flooding on the eastern side of Dhaka that is extremely low lying.
“The flooding in the northern and east-northern regions of Bangladesh is receding as the water levels of the Jamuna, Teesta, Meghna and Surma have decreased. The water level is decreasing slowly because of the new moon and is expected to fall quicker from Friday.”
