Flood situation can get worse due to low pressure in Bay of Bengal and active Monsoon

The low pressure formed over West Central Bay and adjoining Northwest bay of Andhra Pradesh Coast. The low pressure now lies over coastal Orissa and adjoining Northwest Bay of Bengal. It is likely to move west-northwestwards across interior Orissa. The western and eastern end of monsoon trough passes through the centre of low pressure area lying over coastal Orissa to Assam across central part of Bangladesh according to Indian Meteorological Department (IMD). Monsoon is fairly active over Bangladesh and moderate to strong over North Bay.

Light to moderate rain is likely to occur at most places over Khulna, Barishal & Chattogram divisions and at many places over Rangpur, Rajshahi, Mymensingh, Dhaka & Sylhet divisions, says Bangladesh Meteorological Department (BMD).

Heavy water flow from upstream river coupled with monsoon rain can cause flood

The upstream flood water from Ganga basin (India) is causing flood in Padma river. Padma is flowing 8.81mm above danger level in Goalundo point on 18th August 2021, whereas in 18th August of previous year (2020) it was 8.78cm above danger level, the water level in Hardinge Bridge point is 13.79 on 18th August 2021, which was 13.00 on the same day of previous year (2020).

FFWC forecasted that in next 24 hours (from 18th to 19th August), the flood situation at low lying areas of Rajbari and Faridpur district may deteriorate. Due to the flooding of upstream rivers, all the major rivers of the country are in rising trend and it may continue till 20th August except the rivers of Meghna basin (water level in Manu railway bridge is 13.57 in 18th August 2021, was 12.86 in 18th August 2020 and in Chandpur 3.34 on 18th August 2021, was 2.92 in 18th August, 2020).

Moreover, medium to heavy rainfall at places in the South-Eastern and Southern coastal regions of the country can occur which will cause the water levels of the rivers of South-Eastern Cox’s Bazar district and Southern coastal region rise  rapidly from 18th to 20th August.
